ATmega128RFA1
3 Overview
The ATmega128RFA1 is a low-power CMOS 8 bit microcontroller based on the AVR
enhanced RISC architecture combined with a high data rate transceiver for the 2.4 GHz
ISM band. It is derived from the ATmega1281 microcontroller and the AT86RF231 radio
transceiver.
By executing powerful instructions in a single clock cycle, the device achieves
throughputs approaching 1 MIPS per MHz allowing the system designer to optimize
power consumption versus processing speed.
The radio transceiver provides high data rates from 250 kb/s up to 2 Mb/s, frame
handling, outstanding receiver sensitivity and high transmit output power enabling a
very robust wireless communication.
3.1 Block Diagram
Figure 3-1 Block Diagram
The AVR core combines a rich instruction set with 32 general purpose working
registers. All 32 registers are directly connected to the Arithmetic Logic Unit (ALU). Two
independent registers can be accessed with one single instruction executed in one
clock cycle. The resulting architecture is very code efficient while achieving throughputs
up to ten times faster than conventional CISC microcontrollers. The system includes
internal voltage regulation and an advanced power management. Distinguished by the
small leakage current it allows an extended operation time from battery.
The radio transceiver is a fully integrated ZigBee solution using a minimum number of
external components. It combines excellent RF performance with low cost, small size
and low current consumption. The radio transceiver includes a crystal stabilized
fractional-N synthesizer, transmitter and receiver, and full Direct Sequence Spread
3
8266AS-MCU Wireless-12/09
Spectrum Signal (DSSS) processing with spreading and despreading. The device is
fully compatible with IEEE802.15.4-2006/2003 and ZigBee standards.
The ATmega128RFA1 provides the following features: 128 kbytes of In-System
Programmable (ISP) Flash with read-while-write capabilities, 4 kbytes EEPROM, 16
kbytes SRAM, up to 35 general purpose I/O lines, 32 general purpose working
registers, Real Time Counter (RTC), 6 flexible Timer/Counters with compare modes
and PWM, USART, a byte oriented 2-wire Serial Interface, a 8 channel, 10 bit analog to
digital converter (ADC) with an optional differential input stage with programmable gain,
programmable Watchdog Timer with Internal Oscillator, a SPI serial port, IEEE std.
1149.1 compliant JTAG test interface, also used for accessing the On-chip Debug
system and programming and 6 software selectable power saving modes.
The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI port, and
interrupt system to continue functioning. The Power-down mode saves the register
contents but freezes the Oscillator, disabling all other chip functions until the next
interrupt or hardware reset. In Power-save mode, the asynchronous timer continues to
run, allowing the user to maintain a timer base while the rest of the device is sleeping.
The ADC Noise Reduction mode stops the CPU and all I/O modules except
asynchronous timer and ADC, to minimize switching noise during ADC conversions. In
Standby mode, the RC oscillator is running while the rest of the device is sleeping. This
allows very fast start-up combined with low power consumption. In Extended Standby
mode, both the main RC oscillator and the asynchronous timer continue to run.
Typical supply current of the microcontroller with CPU clock set to 16MHz and the radio
transceiver for the most important states is shown in the Figure 3-2 below.

Radio Transceiver State
The transmit output power is set to maximum. If the radio transceiver is in SLEEP mode
the current is dissipated by the AVR microcontroller only.
In Deep Sleep mode all major digital blocks with no data retention requirements are
disconnected from main supply providing a very small leakage current. Watchdog timer,
MAC symbol counter and 32.768kHz oscillator can be configured to continue to run.
The device is manufactured using Atmel’s high-density nonvolatile memory technology.
The On-chip ISP Flash allows the program memory to be reprogrammed in-system

trough an SPI serial interface, by a conventional nonvolatile memory programmer, or by
on on-chip boot program running on the AVR core. The boot program can use any
interface to download the application program in the application Flash memory.
Software in the boot Flash section will continue to run while the application Flash
section is updated, providing true Read-While-Write operation. By combining an 8 bit
RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel
ATmega128RFA1 is a powerful microcontroller that provides a highly flexible and cost
effective solution to many embedded control applications.
The ATmega128RFA1 AVR is supported with a full suite of program and system
development tools including: C compiler, macro assemblers, program
debugger/simulators, in-circuit emulators, and evaluation kits.

Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each
bit). The Port B output buffers have symmetrical drive characteristics with both high sink
and source capability. As inputs, Port B pins that are externally pulled low will source

bit). The Port G output buffers have symmetrical drive characteristics with both high
sink and source capability. However the driver strength of PG3 and PG4 is reduced
compared to the other port pins. The output voltage drop (VOH, VOL) is higher while the
leakage current is smaller. As inputs, Port G pins that are externally pulled low will
source current if the pull-up resistors are activated. The Port G pins are tri-stated when

3.3 Compatibility to ATmega1281/2561
The basic AVR feature set of the ATmega128RFA1 is derived from the
ATmega1281/2561. Address locations and names of the implemented modules and
6

registers are unchanged as long as it fits the target application of a very small and
power efficient radio system. In addition, several new features were added.
Backward compatibility of the ATmega128RFA1 to the ATmega1281/2561 is provided
in most cases. However some incompatibilities between the microcontrollers exist.
3.3.1 Port A and Port C
Port A and Port C are not implemented. The associated registers are available but will
not provide any port control. Remaining ports are kept at their original address location
to not require changes of existing software packages.
3.3.2 External Memory Interface
The alternate pin function “External Memory interface” using Port A and Port C is not
implemented due to the missing ports.
The large internal data memory (SRAM) does not require an external memory and the
associated parallel interface. It keeps the system radiation (EMC) at a very small level
to provide very high sensitivity at the antenna input.
3.3.3 High Voltage Programming Mode
Alternate pin function BS2 (high voltage programming) of pin PA0 is mapped to a
different pin. Entering the parallel programming mode is controlled by the TST pin.
3.3.4 AVR Oscillators and External Clock
The AVR microcontroller can utilize the high performance crystal oscillator of the
2.4GHz transceiver connected to the pins XTAL1 and XTAL2. An external clock can be
applied to the microcontroller using the clock input CLKI.
3.3.5 Analog Frontend
The ATmega128RFA1 has a new A/D converter. Software compatibility is basically
assured. Nevertheless to benefit from the higher conversion speeds and the better
performance some changes are required.

The power supply bypass capacitors (CB2, CB4) are connected to the external analog
supply pin (EVDD, pin 59) and external digital supply pin (DEVDD, pin 23). Pins 34, 44
and 54 supply the digital port pins.
Capacitors CB1 and CB3 are bypass capacitors for the integrated analog and digital
voltage regulators to ensure stable operation and to improve noise immunity.
Capacitors should be placed as close as possible to the pins and should have a lowresistance and low-inductance connection to ground to achieve the best performance.
The crystal (XTAL), the two load capacitors (CX1, CX2), and the internal circuitry
connected to pins XTAL1 and XTAL2 form the 16MHz crystal oscillator for the 2.4GHz
8
ATmega128RFA1
8266AS-MCU Wireless-12/09
ATmega128RFA1
transceiver. To achieve the best accuracy and stability of the reference frequency, large
parasitic capacitances must be avoided. Crystal lines should be routed as short as
possible and not in proximity of digital I/O signals. This is especially required for the
High Data Rate Modes.
The 32.768 kHz crystal connected to the internal low power (sub 1µA) crystal oscillator
provides a stable time reference for all low power modes including 32 Bit IEEE 802.15.4
Symbol Counter ("MAC Symbol Counter") and real time clock application using the
asynchronous timer T/C2 ("Timer/Counter2 with PWM and Asynchronous Operation").
Total capacitance including CX3, CX4 should not exceed 15pF on both pins. The very
low supply current of the oscillator requires careful layout of the PCB and any leakage
path must be avoided.
Crosstalk and radiation from switching digital signals to the crystal pins or the RF pins
can degrade the system performance. The programming of minimum drive strength
settings for the digital output signal is recommended (see "DPDS0 - Port Driver
Strength Register 0").
