Functional Description and Application Information
The i.MX35 consists of the following major subsystems: • ARM1136 Platform—AP domain • SDMA Platform and EMI—Shared domain
2.1
Application Processor Domain Overview
The applications processor (AP) and its domain are responsible for running the operating system and applications software, providing the user interface, and supplying access to integrated and external peripherals. The AP domain is built around an ARM1136JF-S core with 16-Kbyte instruction and data L1 caches, an MMU, a 128-Kbyte L2 cache, a multiported crossbar switch, and advanced debug and trace interfaces.
i.MX35 Applications Processors for Automotive Products, Rev. 8 Freescale Semiconductor 5
The functionality of AP Domain peripherals includes the user interface; the connectivity, display, security, and memory interfaces; and 128 Kbytes of multipurpose SRAM.
2.2
Shared Domain Overview
The shared domain is composed of the shared peripherals, a smart DMA engine (SDMA) and a number of miscellaneous modules. For maximum flexibility, some peripherals are directly accessible by the SDMA engine. The i.MX35 has a hierarchical memory architecture including L1 caches and a unified L2 cache. This reduces the bandwidth demands for the external bus and external memory. The external memory subsystem supports a flexible external memory system, including support for SDRAM (SDR, DDR2 and mobile DDR) and NAND Flash.
2.3
Advanced Power Management Overview
To address the continuing need to reduce power consumption, the following techniques are incorporated in the i.MX35: • Clock gating • Power gating • Power-optimized synthesis • Well biasing The insertion of gating into the clock paths allows unused portions of the chip to be disabled. Because static CMOS logic consumes only leakage power, significant power savings can be realized. “Well biasing” is applying a voltage that is greater than VDD to the nwells, and one that is lower than VSS to the pwells. The effect of applying this well back bias voltage reduces the subthreshold channel leakage. For the 90-nm digital process, it is estimated that the subthreshold leakage is reduced by a factor of ten over the nominal leakage. Additionally, the supply voltage for internal logic can be reduced from 1.4 V to 1.22 V.
2.4
ARM11 Microprocessor Core
The CPU of the i.MX35 is the ARM1136JF-S core, based on the ARM v6 architecture. This core supports the ARM Thumb® instruction sets, features Jazelle® technology (which enables direct execution of Java byte codes) and a range of SIMD DSP instructions that operate on 16-bit or 8-bit data values in 32-bit registers. The ARM1136JF-S processor core features are as follows: • Integer unit with integral EmbeddedICE™ logic • Eight-stage pipeline

The i.MX35 core is intended to operate at a maximum frequency of 532 MHz to support the required multimedia use cases. Furthermore, an image processing unit (IPU) is integrated into the AP domain to offload the ARM11 core from performing functions such as color space conversion, image rotation and scaling, graphics overlay, and pre- and post-processing.

Block Mnemonic ATA Block Name ATA module Domain 1 SDMA Subsystem Connectivity peripherals Multimedia peripherals Brief Description The ATA block is an AT attachment host interface. Its main use is to interface with IDE hard disk drives and ATAPI optical disk drives. It interfaces with the ATA device over a number of ATA signals. The AUDMUX is a programmable interconnect for voice, audio, and synchronous data routing between host serial interfaces (SSIs) and peripheral serial interfaces (audio codecs). The AUDMUX has two sets of interfaces: internal ports to on-chip peripherals and external ports to off-chip audio devices. Data is routed by configuring the appropriate internal and external ports. The CAN protocol is primarily designed to be used as a vehicle serial data bus running at 1 Mbps. This block generates all clocks for the peripherals in the SDMA platform. The CCM also manages ARM1136 platform low-power modes (WAIT, STOP), disabling peripheral clocks appropriately for power conservation, and provides alternate clock sources for the ARM1136 and SDMA platforms. This module is a serial interface equipped with data FIFOs; each master/slave-configurable SPI module is capable of interfacing to both serial port interface master and slave devices. The CSPI ready (SPI_RDY) and slave select (SS) control signals enable fast data communication with fewer software interrupts. ECT (embedded cross trigger) is an IP for real-time debug purposes. It is a programmable matrix allowing several subsystems to interact with each other. ECT receives signals required for debugging purposes (from cores, peripherals, buses, external inputs, and so on) and propagates them (propagation programmed through software) to the different debug resources available within the SoC. The EMI module provides access to external memory for the ARM and other masters. It is composed of the following main submodules: M3IF—provides arbitration between multiple masters requesting access to the external memory. SDRAM CTRL—interfaces to mDDR, DDR2 (4-bank architecture type), and SDR interfaces. NANDFC—provides an interface to NAND Flash memories. WEIM—interfaces to NOR Flash and PSRAM. Each EPIT is a 32-bit “set-and-forget” timer that starts counting after the EPIT is enabled by software. It is capable of providing precise interrupts at regular intervals with minimal processor intervention. It has a 12-bit prescaler to adjust the input clock frequency to the required time setting for the interrupts, and the counter value can be programmed on the fly.

Block Mnemonic ESAI Block Name Enhanced serial audio interface Domain 1 SDMA Subsystem Connectivity peripherals Brief Description The enhanced serial audio interface (ESAI) provides a full-duplex serial port for serial communication with a variety of serial devices, including industry-standard codecs, SPDIF transceivers, and other DSPs. The ESAI consists of independent transmitter and receiver sections, each section with its own clock generator. The eSDHCv2 consists of four main modules: CE-ATA, MMC, SD and SDIO. CE-ATA is a hard drive interface that is optimized for embedded applications of storage. The MultiMediaCard (MMC) is a universal, low-cost, data storage and communication media to applications such as electronic toys, organizers, PDAs, and smart phones. The secure digital (SD) card is an evolution of MMC and is specifically designed to meet the security, capacity, performance, and environment requirements inherent in emerging audio and video consumer electronic devices. SD cards are categorized into Memory and I/O. A memory card enables a copyright protection mechanism that complies with the SDMI security standard. SDIO cards provide high-speed data I/O (such as wireless LAN via SDIO interface) with low power consumption. Note: CE-ATA is not available for the MCIMX351. The Ethernet media access controller (MAC) is designed to support both 10 and 100 Mbps Ethernet/IEEE 802.3 networks. An external transceiver interface and transceiver function are required to complete the interface to the media Used for general purpose input/output to external ICs. Each GPIO module supports 32 bits of I/O. Each GPT is a 32-bit free-running or set-and-forget mode timer with a programmable prescaler and compare and capture registers. A timer counter value can be captured using an external event and can be configured to trigger a capture event on either the leading or trailing edges of an input pulse. When the timer is configured to operate in set-and-forget mode, it is capable of providing precise interrupts at regular intervals with minimal processor intervention. The counter has output compare logic to provide the status and interrupt at comparison. This timer can be configured to run either on an external clock or on an internal clock. This module accelerates OpenVG and GDI graphics. Note: Not available for the MCIMX351.

Block Mnemonic I2C(3) Block Name I2C module Domain 1 ARM Subsystem ARM1136 platform peripherals Brief Description Inter-integrated circuit (I2C) is an industry-standard, bidirectional serial bus that provides a simple, efficient method of data exchange, minimizing the interconnection between devices. I2C is suitable for applications requiring occasional communications over a short distance among many devices. The interface operates at up to 100 kbps with maximum bus loading and timing. The I2C system is a true multiple-master bus, with arbitration and collision detection that prevent data corruption if multiple devices attempt to control the bus simultaneously. This feature supports complex applications with multiprocessor control and can be used for rapid testing and alignment of end products through external connections to an assembly-line computer. The IIM provides the primary user-visible mechanism for interfacing with on-chip fuse elements. Among the uses for the fuses are unique chip identifiers, mask revision numbers, cryptographic keys, and various control signals requiring a fixed value. Each I/O multiplexer provides a flexible, scalable multiplexing solution with the following features: • Up to eight output sources multiplexed per pin • Up to four destinations for each input pin • Unselected input paths held at constant levels for reduced power consumption The IPU supports video and graphics processing functions. It also provides the interface for image sensors and displays. The IPU performs the following main functions: • Preprocessing of data from the sensor or from the external system memory • Postprocessing of data from the external system memory • Post-filtering of data from the system memory with support of the MPEG-4 (both deblocking and deringing) and H.264 post-filtering algorithms • Displaying video and graphics on a synchronous (dumb or memory-less) display • Displaying video and graphics on an asynchronous (smart) display • Transferring data between IPU sub-modules and to/from the system memory with flexible pixel reformatting Can be used for either keypin matrix scanning or general purpose I/O. The MLB is designed to interface to an automotive MOST ring. The OSCAUDIO oscillator provides a stable frequency reference for the PLLs. This oscillator is designed to work in conjunction with an external 24.576-MHz crystal.

The SDMA provides DMA capabilities inside the processor. It is a shared module that implements 32 DMA channels and has an interface to connect to the ARM1136 platform subsystem, EMI interface, and the peripherals. The secure JTAG controller (SJC) provides debug and test control with maximum security. The SPBA controls access to the SDMA peripherals. It supports shared peripheral ownership and access rights to an owned peripheral. Sony/Philips digital transceiver interface The SSI is a full-duplex serial port that allows the processor connected to it to communicate with a variety of serial protocols, including the Freescale Semiconductor SPI standard and the I2C sound (I2S) bus standard. The SSIs interface to the AUDMUX for flexible audio routing. Each UART provides serial communication capability with external devices through an RS-232 cable using the standard RS-232 non-return-to-zero (NRZ) encoding format. Each module transmits and receives characters containing either 7 or 8 bits (program-selectable). Each UART can also provide low-speed IrDA compatibility through the use of external circuitry that converts infrared signals to electrical signals (for reception) or transforms electrical signals to signals that drive an infrared LED (for transmission).

Block Mnemonic USBOH Block Name Domain 1 Subsystem Connectivity peripherals Brief Description The USB module provides high performance USB on-the-go (OTG) functionality (up to 480 Mbps), compliant with the USB 2.0 specification, the OTG supplement, and the ULPI 1.0 low pin count specification. The module has DMA capabilities handling data transfer between internal buffers and system memory. Each module protects against system failures by providing a method of escaping from unexpected events or programming errors. Once activated, the timer must be serviced by software on a periodic basis. If servicing does not take place, the watchdog times out and then either asserts a system reset signal or an interrupt request signal, depending on the software configuration.

EMI I/O interface power supply should be set up according to external memory. For example, if using SDRAM then NVCC_EMI1,2,3 should all be set at 3.3 V (typ.). If using MDDR or DDR2, NVC_EMI1,2,3 must be set at 1.8 V (typ.). 2 MLB interface I/O pads can be programmed to function as GPIO by setting NVCC_MLB to 1.8 or 3.3 V, but if used as MLB pads, NVCC_MLB must be set to 2.5 V in order to be compliant with external MOST devices. NVCC_MLB may be left floating. 3 The Fusebox read supply is connected to supply of the full speed USB PHY. FUSE_VDD is only used for programming. It is recommended that FUSE_VDD be connected to ground when not being used for programming. FUSE_VDD should be supplied by following the power up sequence given in Section 4.3.1, “Powering Up.”

Supply Power-Up/Power-Down Requirements and Restrictions
CAUTION Any i.MX35 board design must comply with the power-up and power-down sequence guidelines as described in this section to guarantee reliable operation of the device. Any deviation from these sequences can result in irreversible damage to the i.MX35 processor (worst-case scenario).
This section provides power-up and power-down sequence guidelines for the i.MX35 processor.

4.3.1
Powering Up
The power-up sequence should be completed as follows: 1. Assert Power on Reset (POR). 2. Turn on digital logic domain and IO power supply: VDDn, NVCCx 3. Wait until VDDn and NVCCx power supplies are stable + 32 μs. 4. Turn on all other power supplies: PHY1_VDDA, USBPHY1_VDDA_BIAS, PHY2_VDD, USBPHY1_UPLLVDD, OSC24M_VDD, OSC_AUDIO_VDD, MVDD, PVDD, FUSEVDD. (Always FUSE_VDD should be connected to ground, except when eFuses are to be programmed.) 5. Wait until PHY1_VDDA, USBPHY1_VDDA_BIAS, PHY2_VDD, USBPHY1_UPLLVDD, OSC24M_VDD, OSC_AUDIO_VDD, MVDD, PVDD, (FUSEVDD, optional). Power supplies are stable + 100 μs. 6. Deassert the POR signal.

Powering Down
The power-up sequence in reverse order is recommended for powering down. However, all power supplies can be shut down at the same time.
4.4
Reset Timing
There are two ways of resetting the i.MX35 using external pins: • Power On Reset (using the POR_B pin) • System Reset (using the RESET_IN_B pin)
4.4.1
Power On Reset
POR_B is normally connected to a power management integrated circuit (PMIC). The PMIC asserts POR_B while the power supplies are turned on and negates POR_B after the power up sequence is finished. See Figure 2.

POR_B At least 4 CKIL cycles
CKIL
Figure 3. Timing Between POR_B and CKIL for Complete Reset of i.MX35
4.4.2
System Reset
System reset can be achieved by asserting RESET_IN_B for at least 4 CKIL cycles and later negating RESET_IN_B. The following modules are not reset upon system reset: RTC, PLLs, CCM, and IIM. POR_B pin must be deasserted all the time.

Power Characteristics
The table shows values representing maximum current numbers for the i.MX35 under worst case voltage and temperature conditions. These values are derived from the i.MX35 with core clock speeds up to 532 MHz. Common supplies have been bundled according to the i.MX35 power-up sequence requirements. Peak numbers are provided for system designers so that the i.MX35 power supply requirements will be satisfied during startup and transient conditions. Freescale recommends that system current measurements be taken with customer-specific use-cases to reflect normal operating conditions in the end system.

Assuming the i.MX35 chip is already fully powered; it is still possible to reset all of the modules to their default reset by asserting POR_B for at least 4 CKIL cycles and later de-asserting POR_B. This method of resetting the i.MX35 can also be supported by tying the POR_B and RESET_IN_B pins together.

This rail is connected to ground; it only needs a voltage if eFuses are to be programmed. FUSE_VDD should be supplied by following the power up sequence given in Section 4.3.1, “Powering Up.”
The method for obtaining max current is as follows: 1. Measure worst case power consumption on individual rails using directed test on i.MX35. 2. Correlate worst case power consumption power measurements with worst case power consumption simulations. 3. Combine common voltage rails based on power supply sequencing requirements 4. Guard band worst case numbers for temperature and process variation. Guard band is based on process data and correlated with actual data measured on i.MX35. 5. The sum of individual rails is greater than real world power consumption, as a real system does not typically maximize power consumption on all peripherals simultaneously.

DPLL Electrical Specifications
There are three PLLs inside the i.MX35, all based on the same PLL design. The reference clock for these PLLs is normally generated from an external 24-MHz crystal connected to an internal oscillator via EXTAL24M and XTAL24 pins. It is also possible to connect an external 24-MHz clock directly to EXTAL24M, bypassing the internal oscillator. DPLL specifications are listed in Table 27.

Wireless External Interface Module (WEIM)
All WEIM output control signals may be asserted and deasserted by internal clocks related to the BCLK rising edge or falling edge according to the corresponding assertion or negation control fields. The address always begins related to BCLK falling edge but may be ended both on rising and falling edge in muxed mode according to control register configuration. Output data begins related to BCLK rising edge except in muxed mode where both rising and falling edge may be used according to control register configuration.

Timing parameters are relevant only to SDR SDRAM. For the specific DDR SDRAM data related timing parameters, see Table 41 and Table 42.
NOTE SDR SDRAM CLK parameters are measured from the 50% point—that is, high is defined as 50% of signal value and low is defined as 50% of signal value. SD1 + SD2 does not exceed 7.5 ns for 133 MHz. The timing parameters are similar to the ones used in SDRAM data sheets—that is, Table 33 indicates SDRAM requirements. All output signals are driven by the ESDCTL at the negative edge of SDCLK and the parameters are measured at maximum memory frequency.

This section describes the electrical information of the FEC module. The FEC is designed to support both 10- and 100-Mbps Ethernet networks. An external transceiver interface and transceiver function are required to complete the interface to the media. The FEC supports the 10/100 Mbps Media Independent Interface (MII) using a total of 18 pins. The 10-Mbps 7-wire interface that is restricted to a 10-Mbps data rate uses seven of the MII pins for connection to an external Ethernet transceiver.

FEC AC Timing
This section describes the AC timing specifications of the FEC. The MII signals are compatible with transceivers operating at a voltage of 3.3 V.

MII Receive Signal Timing
The MII receive timing signals consist of FEC_RXD[3:0], FEC_RX_DV, FEC_RX_ER, and FEC_RX_CLK. The receiver functions correctly up to a FEC_RX_CLK maximum frequency of 25 MHz + 1%. There is no minimum frequency requirement. Additionally, the processor clock frequency must exceed twice the FEC_RX_CLK frequency. Table 45 lists MII receive channel timings.

A device must internally provide a hold time of at least 300 ns for the I2DAT signal in order to bridge the undefined region of the falling edge of I2CLK. The maximum hold time has to be met only if the device does not stretch the LOW period (ID IC6) of the I2CLK signal. A fast-mode I2C-bus device can be used in a standard-mode I2C-bus system, but the requirement of set-up time (ID IC7) of 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the I2CLK signal. If such a device does stretch the LOW period of the I2CLK signal, it must output the next data bit to the I2DAT line max_rise_time (ID No IC10) + data_setup_time (ID No IC8) = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the I2CLK line is released.

4.9.12.2
Functional Description
There are three timing modes supported by the IPU. 4.9.12.2.1 Pseudo BT.656 Video Mode
Smart camera sensors, which typically include image processing capability, support video mode transfer operations. They use an embedded timing syntax to replace the SENSB_VSYNC and SENSB_HSYNC signals. The timing syntax is defined by the BT.656 standard. This operation mode follows the recommendations of the ITU BT.656 specifications. The only control signal used is SENSB_PIX_CLK. Start-of-frame and active-line signals are embedded in the data stream. An active line starts with a SAV code and ends with an EAV code. In some cases, digital blanking is

inserted in between EAV and SAV code. The CSI decodes and filters out the timing coding from the data stream, thus recovering SENSB_VSYNC and SENSB_HSYNC signals for internal use. 4.9.12.2.2 Gated Clock Mode
Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MCIMX351AVM4B, MCIMX351AVM5B, MCIMX355AVM4B, MCIMX355AVM5B, MCIMX356AVM4B, and MCIMX356AVM5B.
The SENSB_VSYNC, SENSB_HSYNC, and SENSB_PIX_CLK signals are used in this mode. See Figure 45.

Figure 45. Gated Clock Mode Timing Diagram
A frame starts with a rising edge on SENSB_VSYNC (all the timing corresponds to straight polarity of the corresponding signals). Then SENSB_HSYNC goes to high and hold for the entire line. The pixel clock is valid as long as SENSB_HSYNC is high. Data is latched at the rising edge of the valid pixel clocks. SENSB_HSYNC goes to low at the end of the line. Pixel clocks then become invalid and the CSI stops receiving data from the stream. For the next line, the SENSB_HSYNC timing repeats. For the next frame, the SENSB_VSYNC timing repeats. 4.9.12.2.3 Non-Gated Clock Mode
The timing is the same as the gated-clock mode (described in Section 4.9.12.2.2, “Gated Clock Mode”), except for the SENSB_HSYNC signal, which is not used. See Figure 46. All incoming pixel clocks are valid and will cause data to be latched into the input FIFO. The SENSB_PIX_CLK signal is inactive (states low) until valid data is going to be transmitted over the bus.

This section discusses the interfaces to active matrix TFT LCD panels, Sharp HR-TFT, and dual-port smart displays. 4.9.13.1.4 Interface to Active Matrix TFT LCD Panels, Functional Description
Figure 48 depicts the LCD interface timing for a generic active matrix color TFT panel. In this figure, signals are shown with negative polarity. The sequence of events for active matrix interface timing is as follows: • DISPB_D3_CLK latches data into the panel on its negative edge (when positive polarity is selected). In active mode, DISPB_D3_CLK runs continuously. • DISPB_D3_HSYNC causes the panel to start a new line. • DISPB_D3_VSYNC causes the panel to start a new frame. It always encompasses at least one HSYNC pulse. • DISPB_D3_DRDY acts like an output enable signal to the CRT display. This output enables the data to be shifted to the display. When disabled, the data is invalid and the trace is off.

Functionality and electrical characteristics of the synchronous interface to dual-port smart displays are identical to parameters of the synchronous interface. See Section 4.9.13.1.5, “Interface to Active Matrix TFT LCD Panels, Electrical Characteristics.” 4.9.13.3.6 Interface to a TV Encoder—Functional Description
The interface has an 8-bit data bus, transferring a single 8-bit value (Y/U/V) in each cycle. The bits D7–D0 of the value are mapped to bits LD17–LD10 of the data bus, respectively. Figure 53 depicts the interface timing. • The frequency of the clock DISPB_D3_CLK is 27 MHz. • The DISPB_D3_HSYNC, DISPB_D3_VSYNC and DISPB_D3_DRDY signals are active low. • The transition to the next row is marked by the negative edge of the DISPB_D3_HSYNC signal. It remains low for a single clock cycle. • The transition to the next field/frame is marked by the negative edge of the DISPB_D3_VSYNC signal. It remains low for at least one clock cycle. — At a transition to an odd field (of the next frame), the negative edges of DISPB_D3_VSYNC and DISPB_D3_HSYNC coincide. — At a transition to an even field (of the same frame), they do not coincide. • The active intervals—during which data is transferred—are marked by the DISPB_D3_HSYNC signal being high.

4.9.13.4
Asynchronous Interfaces
This section discusses the asynchronous parallel and serial interfaces. 4.9.13.4.8 Parallel Interfaces, Functional Description
The IPU supports the following asynchronous parallel interfaces: • System 80 interface — Type 1 (sampling with the chip select signal) with and without byte enable signals. — Type 2 (sampling with the read and write signals) with and without byte enable signals. • System 68k interface — Type 1 (sampling with the chip select signal) with or without byte enable signals. — Type 2 (sampling with the read and write signals) with or without byte enable signals. For each of four system interfaces, there are three burst modes: 1. Burst mode without a separate clock—The burst length is defined by the corresponding parameters of the IDMAC (when data is transferred from the system memory) or by the HBURST signal (when the MCU directly accesses the display via the slave AHB bus). For system 80 and system 68k type 1 interfaces, data is sampled by the CS signal and other control signals change only when transfer direction is changed during the burst. For type 2 interfaces, data is sampled by the WR/RD signals (system 80) or by the ENABLE signal (system 68k), and the CS signal stays active during the whole burst. 2. Burst mode with the separate clock DISPB_BCLK—In this mode, data is sampled with the DISPB_BCLK clock. The CS signal stays active during whole burst transfer. Other controls are changed simultaneously with data when the bus state (read, write or wait) is altered. The CS signals and other controls move to non-active state after burst has been completed. 3. Single access mode—In this mode, slave AHB and DMA burst are broken to single accesses. The data is sampled with CS or other controls according to the interface type as described above. All controls (including CS) become non-active for one display interface clock after each access. This mode corresponds to the ATI single access mode. Both system 80 and system 68k interfaces are supported for all described modes as depicted in Figure 54, Figure 55, Figure 56, and Figure 57. These timing images correspond to active-low DISPB_Dn_CS, DISPB_Dn_WR and DISPB_Dn_RD signals.

Loopback delay Tlbd is the cumulative propagation delay of read controls and read data. It includes an IPU output delay, a device – level output delay, board delays, a device – level input delay, an IPU input delay. This value is device specific.
The following parameters are programmed via the DI_DISP#_TIME_CONF_1, DI_DISP#_TIME_CONF_2, and DI_HSP_CLK_PER registers: • DISP#_IF_CLK_PER_WR, DISP#_IF_CLK_PER_RD • HSP_CLK_PERIOD • DISP#_IF_CLK_DOWN_WR • DISP#_IF_CLK_UP_WR • DISP#_IF_CLK_DOWN_RD • DISP#_IF_CLK_UP_RD • DISP#_READ_EN

Serial Interfaces, Functional Description
The IPU supports the following types of asynchronous serial interfaces: • 3-wire (with bidirectional data line) • 4-wire (with separate data input and output lines) • 5-wire type 1 (with sampling RS by the serial clock) • 5-wire type 2 (with sampling RS by the chip select signal) Figure 63 depicts timing of the 3-wire serial interface. The timing images correspond to active-low DISPB_D#_CS signal and the straight polarity of the DISPB_SD_D_CLK signal. For this interface, a bidirectional data line is used outside the device. The IPU still uses separate input and output data lines (IPP_IND_DISPB_SD_D and IPP_DO_DISPB_SD_D). The I/O mux connects the internal data lines to the bidirectional external line according to the IPP_OBE_DISPB_SD_D signal provided by the IPU. Each data transfer can be preceded by an optional preamble with programmable length and contents. The preamble is followed by read/write (RW) and address (RS) bits. The order of the these bits is programmable. The RW bit can be disabled. The following data can consist of one word or of a whole burst. The interface parameters are controlled by the DI_SER_DISPn_CONF registers (n = 1, 2).

The MLB controller can shut off MLBCLK to place MediaLB in a low-power state. Pulse width variation is measured at 1.25 V by triggering on one edge of MLBCLK and measuring the spread on the other edge, measured in ns peak-to-peak (pp) The board must be designed to insure that the high-impedance bus does not leave the logic state of the final driven bit for this time period. Therefore, coupling must be minimized while meeting the maximum capacitive load listed.

The parallel ATA module can work on PIO/multiword DMA/ultra-DMA transfer modes (not available for the MCIMX351). Each transfer mode has a different data transfer rate, Ultra DMA mode 4 data transfer rate is up to 100 MBps. The parallel ATA module interface consists of a total of 29 pins. Some pins have different functions in different transfer modes. There are various requirements for timing relationships among the function pins, in compliance with the ATA/ATAPI-6 specification, and these requirements are configurable by the ATA module registers.

ATA Electrical Specifications (ATA Bus, Bus Buffers)
This section discusses ATA parameters. For a detailed description, refer to the ATA-6 specification. Level shifters are required for 3.3-V or 5.0-V compatibility on the ATA interface. The use of bus buffers introduces delays on the bus and introduces skew between signal lines. These factors make it difficult to operate the bus at the highest speed (UDMA-5) when bus buffers are used. Use of bus buffers is not recommended if fast UDMA mode is required. The ATA specification imposes a slew rate limit on the ATA bus. According to this limit, any signal driven on the bus should have a slew rate between 0.4 and 1.2 V/ns with a 40 pF load. Few vendors of bus buffers specify the slew rate of the outgoing signals. When bus buffers are used the ata_data bus buffer is bidirectional, and uses the direction control signal ata_buffer_en. When ata_buffer_en is asserted, the bus should drive from host to device. When

101
ata_buffer_en is negated, the bus drives from device to host. Steering of the signal is such that contention on the host and device tri-state buses is always avoided.

Timing Parameters
Table 65 shows the parameters used in the timing equations. These parameters depend on the implementation of the ATA interface on silicon, the bus buffer used, the cable delay, and the cable skew.

SSI Electrical Specifications
NOTE All of the timing for the SSI is 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. All timing is on AUDMUX signals when SSI is being used for data transfer. “Tx” and “Rx” refer to the transmit and receive sections of the SSI, respectively. For internal frame sync operations using the external clock, the FS timing will be the same as that of Tx Data (for example, during AC97 mode of operation).

Table 91 and Table 92 list MAPBGA signals, alphabetized by signal name, for silicon revisions 2.0 and 2.1, respectively. Table 93 and Table 94 show the signal assignment on the i.MX35 ball map for silicon revisions 2.0 and 2.1, respectively. The ball map for silicon revision 2.1 is different than the ballmap for silicon revision 2.0. The layout for each revision is not compatible, so it is important that the correct ballmap be used to implement the layout.
