1.4 Conventions

This document uses the following conventions:

• OVERBAR is used to indicate a signal that is active when pulled low: for example, RESET.

•

Logic level one

is a voltage that corresponds to Boolean true (1) state.

•

Logic level zero

is a voltage that corresponds to Boolean false (0) state.

• To set a bit or bits means to establish logic level one.

• To clear a bit or bits means to establish logic level zero.

• A signal is an electronic construct whose state conveys or changes in state convey information.

• A pin is an external physical connection. The same pin can be used to connect a number of signals.

•

Asserted

means that a discrete signal is in active logic state.

— Active low signals change from logic level one to logic level zero.

— Active high signals change from logic level zero to logic level one.

•

Negated

means that an asserted discrete signal changes logic state.

— Active low signals change from logic level zero to logic level one.

— Active high signals change from logic level one to logic level zero.

• LSB means least significant bit or bits, and MSB means most significant bit or bits. References to low and high bytes or words are spelled out.

• Numbers preceded by a percent sign (%) are binary. Numbers preceded by a dollar sign ($) or 0x are hexadecimal.

Function/Notes

External Bus/Chip-Select (EIM)

Address bus signals

Data bus signals

MSB Byte Strobe—Active low external enable byte signal that controls D [31:24].

Byte Strobe—Active low external enable byte signal that controls D [23:16].

Byte Strobe—Active low external enable byte signal that controls D [15:8].

LSB Byte Strobe—Active low external enable byte signal that controls D [7:0].

Memory Output Enable—Active low output enables external data bus.

Chip-Select—The chip-select signals CS [3:2] are multiplexed with CSD [1:0] and are selected by the

Function Multiplexing Control Register (FMCR). By default CSD [1:0] is selected.

Active low input signal sent by a flash device to the EIM whenever the flash device must terminate an on-going burst sequence and initiate a new (long first access) burst sequence.

Active low signal sent by a flash device causing the external burst device to latch the starting burst address.

Clock signal sent to external synchronous memories (such as burst flash) during burst mode.

RW signal—Indicates whether external access is a read (high) or write (low) cycle. Used as a WE input signal by external DRAM.

DTACK signal—The external input data acknowledge signal. When using the external DTACK signal as a data acknowledge signal, the bus time-out monitor generates a bus error when a bus cycle is not terminated by the external DTACK signal after 1022 clock counts have elapsed.

Bootstrap

System Boot Mode Select—The operational system boot mode of the i.MXS processor upon system reset is determined by the settings of these pins.

SDRAM Controller

SDRAM non-interleave mode bank address multiplexed with address signals A [15:11]. These signals are logically equivalent to core address p_addr [25:21] in SDRAM cycles.

SDRAM interleave addressing mode bank address multiplexed with address signals A [19:16]. These signals are logically equivalent to core address p_addr [12:9] in SDRAM cycles.

SDRAM address signals

SDRAM address signals which are multiplexed with address signals A [10:1]. MA [9:0] are selected on

SDRAM cycles.

SDRAM data enable

SDRAM Chip-select signal which is multiplexed with the CS2 signal. These two signals are selectable by programming the system control register.

32 kHz crystal output

Clock Out signal selected from internal clock signals.

Master Reset—External active low Schmitt trigger input signal. When this signal goes active, all modules (except the reset module and the clock control module) are reset.

Reset Out—Internal active low output signal from the Watchdog Timer module and is asserted from the following sources: Power-on reset, External reset (RESET_IN), and Watchdog time-out.

Power On Reset—Internal active high Schmitt trigger input signal. The POR signal is normally generated by an external RC circuit designed to detect a power-up event.

JTAG

Test Reset Pin—External active low signal used to asynchronously initialize the JTAG controller.

Serial Output for test instructions and data. Changes on the falling edge of TCK.

Serial Input for test instructions and data. Sampled on the rising edge of TCK.

Test Clock to synchronize test logic and control register access through the JTAG port.

Test Mode Select to sequence the JTAG test controller’s state machine. Sampled on the rising edge of

TCK.

DMA

DMA Request—external DMA request signal. Multiplexed with SPI1_SPI_RDY.

Big Endian—Input signal that determines the configuration of the external chip-select space. If it is driven logic-high at reset, the external chip-select space will be configured to big endian. If it is driven logic-low at reset, the external chip-select space will be configured to little endian. This input must not change state after power-on reset negates or during chip operation.

2.1 I/O Pads Power Supply and Signal Multiplexing Scheme

This section describes detailed information about both the power supply for each I/O pin and its function multiplexing scheme. The user can reference information provided in

Table 6 on page 17 to configure the

power supply scheme for each device in the system (memory and external peripherals). The function

multiplexing information also shown in Table 6 allows the user to select the function of each pin by

configuring the appropriate GPIO registers when those pins are multiplexed to provide different functions.

A typical application with 30 pads simultaneously switching assumes the GPIO toggling and instruction fetches from the ARM

® core-that is, 7x GPIO, 15x Data bus, and 8x Address bus.

A worst-case application with 70 pads simultaneously switching assumes the GPIO toggling and instruction fetches from the

ARM core-that is, 32x GPIO, 30x Data bus, 8x Address bus. These calculations are based on the core running its heaviest OS application at 100MHz, and where the whole image is running out of SDRAM. QVDD at 1.9V, NVDD and AVDD at 3.3V, therefore, 180mA is the worst measurement recorded in the factory environment, max 5mA is consumed for OSC pads, with each toggle GPIO consuming 4mA.

3.2 Recommended Operating Range

Table 5

provides the recommended operating ranges for the supply voltages and temperatures. The i.MXS processor has multiple pairs of VDD and VSS power supply and return pins. QVDD and QVSS pins are used for internal logic. All other VDD and VSS pins are for the I/O pads voltage supply, and each pair of

VDD and VSS provides power to the enclosed I/O pads. This design allows different peripheral supply voltage levels in a system.

Because AVDD pins are supply voltages to the analog pads, it is recommended to isolate and noise-filter the AVDD pins from other VDD pins.

For more information about I/O pads grouping per VDD, please refer to Table 2 on page 4 .

Functional Description and Application Information

4.1 Embedded Trace Macrocell

All registers in the ETM9 are programmed through a JTAG interface. The interface is an extension of the

ARM920T processor’s TAP controller, and is assigned scan chain 6. The scan chain consists of a 40-bit shift register comprised of the following:

• 32-bit data field

• 7-bit address field

• A read/write bit

The data to be written is scanned into the 32-bit data field, the address of the register into the 7-bit address field, and a 1 into the read/write bit.

A register is read by scanning its address into the address field and a 0 into the read/write bit. The 32-bit data field is ignored. A read or a write takes place when the TAP controller enters the UPDATE-DR state.

The timing diagram for the ETM9 is shown in Figure 2 . See Table 9

for the ETM9 timing parameters used

in Figure 2 .

POR width is dependent on the 32 or 32.768 kHz crystal oscillator start-up time. Design margin should allow for crystal tolerance, i.MX chip variations, temperature impact, and supply voltage influence. Through the process of supplying crystals for use with CMOS oscillators, crystal manufacturers have developed a working knowledge of start-up time of their crystals.

Typically, start-up times range from 400 ms to 1.2 seconds for this type of crystal.

If an external stable clock source (already running) is used instead of a crystal, the width of POR should be ignored in calculating timing for the start-up process.

4.4 External Interface Module

The External Interface Module (EIM) handles the interface to devices external to the i.MXS processor, including the generation of chip-selects for external peripherals and memory. The timing diagram for the

EIM is shown in

4.4.1 DTACK Signal Description

The DTACK signal is the external input data acknowledge signal. When using the external DTACK signal as a data acknowledge signal, the bus time-out monitor generates a bus error when a bus cycle is not terminated by the external DTACK signal after 1022 HCLK counts have elapsed. Only the CS5 group supports DTACK signal function when the external DTACK signal is used for data acknowledgement.

Maximum frequency of LCDC_CLK is 48 MHz, which is controlled by Peripheral Clock Divider Register.

Maximum frequency of SCLK is HCLK / 5, otherwise LD output will be wrong.

VSYN, HSYN and SCLK can be programmed as active high or active low. In the above timing diagram, all these 3 signals are active high.

Tpix is the pixel clock period which equals LCDC_CLK period * (PCD + 1).

Ts is the shift clock period. Ts = Tpix * (panel data bus width).

4.5 SPI Timing Diagrams

To use the internal transmit (TX) and receive (RX) data FIFOs when the SPI module is configured as a master, two control signals are used for data transfer rate control: the SS signal (output) and the SPI_RDY signal (input). The SPI1 Sample Period Control Register (PERIODREG1) can also be programmed to a fixed data transfer rate. When the SPI module is configured as a slave, the user can configure the SPI1

Control Register (CONTROLREG1) to match the external SPI master’s timing. In this configuration, SS becomes an input signal, and is used to latch data into or load data out to the internal data shift registers,

as well as to increment the data FIFO. Figure 34 through Figure 38

show the timing relationship of the master SPI using different triggering mechanisms.

4.7 Pulse-Width Modulator

The PWM can be programmed to select one of two clock signals as its source frequency. The selected clock signal is passed through a divider and a prescaler before being input to the counter. The output is available at the pulse-width modulator output (PWMO) external pin. Its timing diagram is shown in

Figure 42

and the parameters are listed in

4.9 USB Device Port

Four types of data transfer modes exist for the USB module: control transfers, bulk transfers, isochronous transfers, and interrupt transfers. From the perspective of the USB module, the interrupt transfer type is identical to the bulk data transfer mode, and no additional hardware is supplied to support it. This section covers the transfer modes and how they work from the ground up.

Data moves across the USB in packets. Groups of packets are combined to form data transfers. The same packet transfer mechanism applies to bulk, interrupt, and control transfers. Isochronous data is also moved in the form of packets, however, because isochronous pipes are given a fixed portion of the USB bandwidth at all times, there is no end-of-transfer.

4.11 Synchronous Serial Interface

The transmit and receive sections of the SSI can be synchronous or asynchronous. In synchronous mode, the transmitter and the receiver use a common clock and frame synchronization signal. In asynchronous mode, the transmitter and receiver each have their own clock and frame synchronization signals.

Continuous or gated clock mode can be selected. In continuous mode, the clock runs continuously. In gated clock mode, the clock functions only during transmission. The internal and external clock timing diagrams

are shown in Figure 51 through

Figure 53

Normal or network mode can also be selected. In normal mode, the SSI functions with one data word of

I/O per frame. In network mode, a frame can contain between 2 and 32 data words. Network mode is typically used in star or ring-time division multiplex networks with other processors or codecs, allowing interface to time division multiplexed networks without additional logic. Use of the gated clock is not allowed in network mode. These distinctions result in the basic operating modes that allow the SSI to communicate with a wide variety of devices.

All the timings for the SSI are given for a non-inverted serial clock polarity (TSCKP/RSCKP = 0) and a non-inverted frame sync

(TFSI/RFSI = 0). If the polarity of the clock and/or the frame sync have been inverted, all the timing remains valid by inverting the clock signal STCK/SRCK and/or the frame sync STFS/SRFS shown in the tables and in the figures.

There are 2 sets of I/O signals for the SSI module. They are from Port C primary function (pad 257 to pad 261) and Port B alternate function (pad 283 to pad 288). When SSI signals are configured as outputs, they can be viewed both at Port C primary function and Port B alternate function. When SSI signals are configured as input, the SSI module selects the input based on status of the FMCR register bits in the Clock controller module (CRM). By default, the input are selected from Port C primary function.
