Description
Digital section
SPI/UART
The MLX90130 is a 13.56MHz, fully integrated, multi-protocol RFID transceiver IC. It has been designed to handle sub-carrier frequencies from
106 to 848 kHz and baud rates up to 848kbit/s. microcontroller
Figure 1: MLX90130 functional diagram
The dual driver architecture of the MLX90130 requires minimal external support components and allows the transmitter to provide up to 300 milliwatts RF power to an appropriate antenna load. This delivered power is suitable for most short to mid range applications.
The digital section of the MLX90130 handles the low protocol layers from API to physical layer using advanced bit and frame encoding/decoding functions. It contains a digital demodulator based on sub-carrier detection and a programmable bit/symbol encoder/decoder. It also encodes and decodes the start and stop bits, parity bits, extra guard time (EGT), start and end of frame
(SOF/EOF) and CRC.
Its 256 bytes buffer allows buffering of an entire
RFID frame. The SPI/UART communication ports guarantee easy interface with the majority of microcontrollers, especially the low cost ones.

Figure 2: MLX90130 simplified block diagram
Power supply
The MLX90130 requires a nominal stable external power supply from 2.7 to 5.5 volt. The current drain depends on the antenna impedance and on the output matching network configuration.
TX Drivers
The transmission drivers are each composed of a differential D class output stage and a programmable modulation index control block. They drive the antenna according to a dual buffer output architecture. The drivers provide modulation index depth capability. They require minimal external support components and allow the transmitter part to provide up to 300 mW RF power to a suitable antenna load.
RX Chain
This chain performs analog demodulation, filtering, amplification and digitizing operations. The receiver inputs are typically connected to the antenna through 2 external attenuation resistors to avoid saturation of the internal detector. The received signal is demodulated, filtered and finally digitized to provide a digital output signal. It is then fed to the digital section for further processing. The complete receiver chain is automatically configured according to the characteristics of the received information and the protocol in use.
Digital control & protocol handling
This block handles the control of the device and the frame coding and decoding parts of the protocols supported by the MLX90130. The MLX90130 provides to the external application, pure payload information after removing frame related information (such as SOF, EOF, EGT …). It can be configured to calculate the
CRC for each communication protocol.
Interface Block
The MLX90130 is addressed through SPI or UART interfaces with a specific and simple set of commands making the life of application programmers easier. A 256 bytes buffer allows minimum interaction with the external low cost microcontroller. This reduces the burden of the microcontroller whose resources can be fully dedicated for the application.

TAG/FIELD Detector
This block manages the enhanced Tag/Card detection capabilities, as well as Field detection. It generates detection signal that is available for the application microcontroller through the interrupt pin (IRQ_OUT). It allows the use of the MLX90130 with low power consumption constraints. An internal state machine handles the RF timings field generation burst..
Reference clock and internal oscillator
The built-in reference oscillator works with a reference crystal of 27.12MHz while, the internal nominal system clock frequency (HFO) is 13.56 MHz. An internal low frequency RC oscillator (LFO) at 32 kHz is also implemented. This block provides the low frequency clock to manage programmable wake-ups in Tag/Card detection as well as in Field detection modes.
Power management
The MLX90130 offers 2 modes and 5 different states of operation allowing ultra low power consumption of the whole system. In hibernate state; the device consumes typically 1µA, while the current consumption in sleep state is of 20µA. In ready state (RF field OFF), the current consumption is typically of 2.5mA and in
TAG detection state, the current consumption is typically of 50µA.
Note: In Active mode and TAG detection states, power consumption depends on the antenna load and on the operating conditions. For more information on power consumption in tag detection, please refer to the

3 Power Management and Operating modes
The MLX90130 features 2 main operating modes: Idle and Active, with 6 different states of operation, as described on the table below:
Mode State Description
Hibernate
Lowest power consumption, the MLX90130 wakes-up with low level pulse on IRQ_IN pin
Idle
Sleep
Tag detection
Ready
Low Power consumption: Wake-up source to exit from this mode is configurable:
- Timer
- IRQ_in pin (low-level)
- NSS pin (low-level)
- Field detector
Low power consumption: Tag detection feature, wake up source is configurable
- Timer
- IRQ_in pin (low level)
- NSS pin (low level)
- Tag detector (mandatory)
High frequency oscillator (HFO) is running. In this mode the
MLX90130 is in reader mode with its HF turned OFF. The
MLX90130 waits for a command from external application, through the selected serial interface (SPI or UART).
Active
Reader
High frequency oscillator (HFO) is running. In this mode the
MLX90130 is selected in RFID reader mode with its HF field set
ON. The MLX90130 is able to receive and execute commands through the selected serial interface (SPI or UART) and is able to communicate with RFID transponders, according to the selected protocol. In Reader mode, the command “SendRecv” is used to send and receive information from an RFID transponder
Table 2: MLX90130 Operating modes & States
one of these states is activated, an appropriate source signal is required to wake-up the device (see description above). The wake-up time from Sleep or Hibernate to Ready state is typically 2ms, this time is mainly due to settling time of XTAL oscillator (HFO).
In Reader mode, the MLX90130 is able to communicate with Transponders (TAG). This state is entered using the command
Protocol_select . In Ready state, the MLX90130 is fully enabled but waiting for the
Protocol_select command to enter the Reader state, without settling time penalty.

5 Communication Interface & protocol
Whatever the communication protocol selected (SPI or UART), the principle of communication is always the same: The application sends a command to the MLX90130 and waits for the appropriate answer. A simple and specific set of command allows the configuration and control of the MLX90130.
Application MLX90130
Select protocol
(e.g. ISO15693, Single Sub-carrier)
Send protocol related data, CRC automatically added (e.g. “022000” + CRC)
Protocol selected, ready for communicate
Return TAG answer
(e.g. “001234ABCD”, CRC correct)
Select another protocol
(e.g. ISO14443A, 7-bit mode)
Protocol selected, ready for communicate
Send protocol related data, CRC automatically
(e.g. “26”)
Turn field OFF
Return TAG answer
(e.g. “0400” , Parity is OK, CRC ignored)
Field is OFF
Figure 5: Example of communication with MLX90130
In order to start RFID communication, the application has to choose the protocol and specify some parameters. When the protocol is selected, the application sends data and parses response until the next protocol is selected or a specific parameter is changed.

5.2 SPI
5.2.1 Polling mode
In order to send commands and receive answers, the application software has to pass 3 stages:
1. Send the command to the MLX90130
2. Poll the MLX90130 until it is ready to transmit the response.
3. Read the response.
The application software should never read the MLX90130 without being sure that the device is ready to send its response.
A Control byte is used to specify the communication type and direction (see pictures below):
– 00: Send command to the MLX90130
– 11: Poll the MLX90130
– 10: Read data from the MLX90130
– 01: Reset the MLX90130
The SPI_NSS line is used to select a device on the common SPI bus. The SPI_NSS active level is LOW.
When the SPI_NSS line is inactive, all data sent by the application will be ignored and the SPI_MISO line will be kept in high impedance state.

Figure 8: SPI communication, reading data from the MLX90130
The maximum allowed communication speed is 2Mbps and data must be sampled by the rising edge of the
SCK signal. The SPI communication is most significant bit (MSB) first.
‘Sending’, ‘Polling’ and ‘Reading’ commands must be separated by a high level of the SPI_NSS line. For example, when the application needs to wait for data from the MLX90130, it asserts the SPI_NSS line to low and issues a ‘Polling’ command. By keeping the SPI_NSS line low, the application can continuously read the
Flags waiting for the bit indicating that the MLX90130 is ready (the flags will be automatically updated, no need to send several polling commands). Then, the application has to assert the SPI_NSS line high to finish the polling sequence. The application asserts the SPI_NSS line low again to issue a ‘Reading’ command to read data. When all data is read, the application asserts the SPI_NSS line high.
The MLX90130 can issue as many 'Polling' commands as necessary. For example, the application asserts
SPI_NSS low, issues a 'Polling' commands and reads the flags. If the MLX90130 is not ready, the application can assert the SPI_NSS high and continue its algorithm (measuring temperature, communication with something else). Then, the application can assert SPI_NSS low again and again issues a 'Polling' commands, and so on, as many times as necessary, until the MLX90130 is ready.
Note that at the beginning of the communication, the application does not need to check flags to start the transmission. The MLX90130 is assumed to be ready to receive a command from the application.

Figure 9: SPI communication reset the MLX90130
Control byte 0x01 resets the MLX90130 and places the device in in Ready state, so a wake-up sequence is not necessary.
5.3 IRQ mode
When the MLX90130 is configured to use the SPI serial interface, the pin IRQ_OUT is used to give additional information to the application. When the MLX90130 is ready to send back a reply it sends an Interrupt request by setting a low level on pin IRQ_OUT, which remains low until the application reads the data. The application can use the IRQ mode to skip the polling stage.

Comments
If length of data is Zero, only EOF will be sent. This can be used for anti-collision procedure
For bit oriented protocol, frames could be split by setting the bit SplitFrame to one.
In this case, the MLX90130 will send the last byte of the command with no integer number of bits, according to the field
number of significant bits in last byte.
In reception, the MLX90130 expects to receive the complement (8 – “number of
significant bits in last byte”).
This option is used during anti-collision procedure.
Table 11: Parameter values for “SendRecv” command
1)
The process of automatically calculate and add the parity bit by the MLX90130 can be disabled by setting the bit 4 of the flags to ‘1’. In this case, the applicative MCU must add one byte to the data with the most significant bit corresponding to the parity bit. The other bits of these additional bytes are not considered and can be set to ‘0’ or ‘1’. The datastream will then look like: <DataByte><Parity><DataByte><Parity>.

ISO/IEC14443A is bit oriented protocol, and non-integer amount of bytes can be received. Number of significant bits in
the 1st byte is the same as indicated in
Send command.
To calculate a position of a collision, application has to take index of byte first.
Index of bit indicates a position inside this byte. Note that both indices start from
0 and bit index can be 8, meaning that collision could also affect the parity bit.
Note that collision information is only present when protocol ISO/IEC14443A with a data rate of 106kbps for transmission and reception is selected.
When others protocols are selected, the two additional bytes are not transmitted.

8 Tag Detector
8.1
Operating Principle
The objective of the TAG detector function is to be able to detect the presence of an RFID label/tag in front of the reader’s antenna, with reduced power consumption. The TAG detector function is based on the detection of any variations of the HF field. If an RFID transponder approaches from the reader’s antenna, it influences the amplitude of the generated HF by a loading effect. This variation can then be monitored by the MLX90130 to inform the external host microcontroller that an RFID transponder is approaching the antenna.
When put in TAG detector state, the MLX90130 periodically generates a few periods of HF carrier frequency to monitor the maximum generated amplitude. This value is then compared to two reference levels
DacDataH / DacDataL[7:0] defined by the user. If the monitored level is above DacDataH[7:0] or below
DacDataL[7:0] , the MLX90130 asserts the IRQ
OUT
pin low, to wake-up the external application
command is not issued by the MCU, the MLX90130 goes in sleep mode during a certain waiting period selected by the user and this mechanism is repeated until a TAG is detected or another event appears (e.g. max number of trials reached, wake-up from host MCU …).
The TAG detector state is entered using the Idle command, the value of
DacDataH / DacDataL[7:0] is defined in this command, as well as the number of HF pulses and the time between two HF bursts with respectively the bytes SwingsCnt[7:0] and WUPeriod[7:0] . The MLX90130 can be forced to wake-up after a certain number of trials, even if no TAG has been detected. This number of trials is set using the bits MaxSleep[4:0] .
When the MLX90130 detects a change in the amplitude of the HF field, it makes the assumption that an object is placed near the antenna. The device is able to detect any HF field variation with a very short period of field presence. After a field change has been detected (decrease or increase), the MLX90130 informs the external application microcontroller by generating an IRQ on the pin IRQ
OUT
(SPI interface) or directly sending the WUFlag register value (UART interface). Then, the host microcontroller takes the control of the
MLX90130 and tries communication with the TAG. Before using the TAG detection feature it is necessary to
perform a calibration as shown in the chapter Calibration procedure below.
The bit “ initial DAC compare index” in register EnterCtrlL is used to select the first comparison to be performed when starting the TAG detector state. When set to ‘0’, the TAG detector feature is started with a comparison to DacDataL[7:0] . If set to ‘1’, the TAG detector feature is started with a comparison to
DacDataH[7:0] . Please note that the Iref bit in EnterCtrlH byte has to be set to allow a proper functionality of the TAG detector feature.
The following picture illustrates the TAG detector operation describes above.

13.56MHz RFID Transceiver
8.2 Calibration procedure
The calibration process should be performed with no tag in its near environment. It consists of executing a successive tag detection sequence using a well-known configuration, in order to establish the two specific reference thresholds: DacDataL and DacDataH which will be programmed in the device before entering Tag
Detector Mode. These both thresholds are coded in 6 bits.
During the calibration process, DacDataH value is fixed to 0xFC and the software will vary the DacDataL value from its minimum value (0x00) to its maximum value (0xFC). At each step, the WUflags byte is read to know if the HF level is above or below the low threshold (“tag detected flag” set or not).
At the end of the calibration process, the reference level DacDataRef is found and corresponds to the value of DacDataL for which the wake-up event switches from “WakeUp at the end of MaxSleep cycles” (no tag in the RF field) to “tag detected”.
To avoid too much sensitivity in the tag detection process, the use of a guard band is recommended. This value should correspond to at least 2 DAC steps (Guard = 0x08).
Final recommended values with guard band:
•
DacDataL = DacDataRef – Guard
•
DacDataH = DacDataRef + Guard
The parameters used to define the tag detection calibration sequence (clocking, set-up time, burst duration, etc.) must be the same as those used for the future tag detection sequences. MaxSleep has to be set to ‘0’ for the calibration.
Another and faster way (binary search: 6 steps) to calibrate the Tag Detector is described in the application note AN2_MLX90130_32_TagDetector .
9 Field Detector
The MLX90130 embeds a field detector block to measure the field level of an external HF RFID reader. This can be used to be able to monitor the availability of the channel before switching ON the HF field of the
MLX90130.
HF field has been detected or not. The field detector can also be configured as an option to wake-up from
“Idle” mode.

10 Application Information
10.1 External Antenna network
RF communication performance depends on the external system antenna network and resonance conditions.
The antenna matching of the MLX90130 is reduced to a minimal component count, composed of two serial capacitors Cs and one parallel capacitor Cp. A parallel resistor Rp can also be added to adjust the antenna damping thus reducing detuning effect provoked by the presence of TAGs or Readers in front of the
MLX90130. Two serial resistors R
RX
have to be adjusted in order to avoid entering the clamping region (see
two parallel capacitors can be added at the transmitting outputs.
Figure below gives the composition of the external matching network. For more information, please refer to the application note AN1_MLX90130_32_AntennaDesignGuidelines available on the Melexis web-site.

1. Resonator characteristics given by the crystal/ceramic resonator manufacturer.
2. Based on characterization, not tested in production.
3. The relatively low value of the RF resistor offers a good protection against issues resulting from use in a humid environment, due to the induced leakage and the bias condition change. However, it is recommended to take this point into account if the application is used in tough humidity conditions.
4. tSU(HFO) is the startup time measured from the moment it is enabled (by software) until a stabilized 27.12MHz oscillation is reached.
This value is measured for a standard crystal resonator and it can vary significantly with the crystal manufacturer.
For C
L1 and C
L2
, it is recommended to use high-quality external ceramic capacitors in the 10 pF to 20 pF range, designed for high-frequency applications, and selected to match the requirements of the crystal or
L1 and C
L2 are usually the same size. The crystal manufacturer typically specifies a load capacitance which is the series combination of C
L1 and C
