i.mx27 and i.mx27l data sheet, rev. 1.5 freescale semiconductor 11 functional description and application information the arm926ej-s processor is a fully synthesizable macrocell, with a configurable memory system. both instruction and data caches will be 16 kbytes on the plat form. the cache is virtually accessed and virtually tagged. the data cached has physical tags as well. the mmu provides virtual memory facilities which are required to support various platform operating systems such as symbian os, windows ce, and linux. the mmu contains eight fully associative tlb entries fo r lockdown and 64 set associative entries. refer to the arm926ej-s technical reference manual for more information. 2.3.5 advanced technology attachment (ata) the advanced technology attachment (ata) hos t controller complies with the ata/atapi-6 specification. the primary use of the ata host controller is to interface with ide hard disc drives and advanced technology attachment packet interface (atapi ) optical disc drives. it interfaces with the ata device over a number of ata signals. this host controller supports interface protocols as specified in ata/atapi-6 standard, as follows: ? pio mode 0, 1, 2, 3, and 4 ? multiword dma mode 0, 1, and 2 ? ultra dma modes 0, 1, 2, 3, and 4 with bus clock of 50 mhz or higher ? ultra dma mode 5 with bus clock of 80 mhz or higher before accessing the ata bus, the host must program the timing parameters to be used on the ata bus. the timing parameters control the timing on the ata bus. most timing parameters are programmable as a number of clock cycles (1 to 255). some are implied. all of the ata device-internal registers are visible to users, and they are defined as mirror registers in ata host controller. as specified in ata/atapi-6 standard, all the features/functions are implemented by reading/writing to the device?s internal registers. there are basically two protocols that can be active at the same time on the ata bus, as follows: ? the first and simplest protocol (pio mode acc ess) can be started at any time by the arm926 to the ata bus. the pio mode is a slow protocol, mainly intended to be used to program an ata disc drive, but also can be used to transfer data to/from the disc drive. ? the second protocol is the dma mode access. dma mode is started by the ata interface after receiving a dma request from the drive, and only if the ata interface has been programmed to accept the dma request. in dma mode, either multiword-dma or ultra-dma protocol is used on the ata bus. all transfers between fifo and the host ip or dma ip bus are zero wait states transfer, so a high-speed transfer between fifo and dma/host bus is possible. 2.3.6 digital audio mux (audmux) the digital audio mux (audmux) provides progra mmable interconnecting for voice, audio, and synchronous data routing between host serial interf aces?for example, ssi, sap, and peripheral serial interfaces?such as, audio and voice codecs. the audm ux allows audio system connectivity to be modified through programming, as opposed to altering the design of the system into which the chip is designed. the design of the audmux allows multiple simultaneous audio/voice/data flows between the ports in point-to-point or point-to-multipoint configurations. 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: mcimx27vop4a, mcimx27lvop4a, mcimx27mop4a, mcimx27lmop4a

i.mx27 and i.mx27l data sheet, rev. 1.5 freescale semiconductor 21 functional description and application information 2.3.29 run-time integrity checker (rtic) the run-time integrity checker (rtic) is one of the security components in the i.mx27/mx27l processors. its purpose is to ensure the integrity of the peripheral memory contents and assist with boot authentication. the rtic has the ability to verify the memory contents during system boot and during run-time execution. if the memory contents at runtime fail to match the hash signature, an error in the security monitor is triggered. contact your freescale semiconductor sales office or dist ributor for additional information on scc, rtic, iim, sahara2 2.3.30 symmetric/asymmetric hashing and random accelerator (sahara2) sahara2 is a security co-processor, it implements encryption algorithms (aes, des, and 3des), hashing algorithms (md5, sha-1, sha_224, and sha-256), stream cipher algorithm (arc4), and a hardware random number generator. contact your freescale semiconductor sales office or dist ributor for additional information on scc, rtic, iim, sahara2 2.3.31 security controller module (scc) the security controller module (scc) is a hardware security component. overall, its primary functionality is associated with establishing a centralized security state controller and hardware security state with a hardware configured, unalterable security policy. contact your freescale semiconductor sales office or dist ributor for additional information on scc, rtic, iim, and sahara2. 2.3.32 secure digital host controller (sdhc) the secure digital host controller (sdhc) controls the multimedia card (mmc), secure digital (sd) memory, and i/o cards by sending commands to cards and performing data accesses to/from the cards. the multimedia card/secure digital host (mmc/sd) module integrates both mmc support along with sd memory and i/o functions. the sdhc is fully compatible with the mmc system specification version 3.0, as well as with the sd memory card specification 1.0, and sd i/o specification 1.0 with 1/4 channel(s). the maximum data rate in 4-bit mode is 100 mbps. the sdhc uses a built-in programmable frequency counter for the sdhc bus, and provides a ma skable hardware interrupt for an sdio interrupt, internal status, and fifo status. it has a pair of 32 16-bit data fifo buffers built in. the multimedia card (mmc) is a universal, low-cost data storage and communication media that is designed to cover a wide area of applications, includi ng, for example, electroni c toys, organizers, pdas, and smart phones. the mmc communication is based on an advanced 7-pin serial bus designed to operate in a low-voltage range. the secure digital card (sd) is an evolution of mmc technology, with two additional pins in the form factor. it is specifically designed to meet the security, capacity, performance, and environment requirements inherent in newly emerging audio and video consumer electronic devices. the physical form 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: mcimx27vop4a, mcimx27lvop4a, mcimx27mop4a, mcimx27lmop4a
i.mx27 and i.mx27l data sheet, rev. 1.5 22 freescale semiconductor functional description and application information factor, pin assignment, and data transfer protocol are forward-compatible with the multimedia card with some additions. under sd, it can be categorized in to memory and i/o. the memory card invokes a copyright protection mechanism that complies with the se curity of the sdmi standard, which is faster and provides the capability for a higher memory capacity. the i/o card provides high-speed data i/o with low-power consumption for mobile electronic devices. 2.3.33 smart liquid crystal display controller module (slcdc) the smart liquid crystal display controller (slcdc) module transfers data from the display memory buffer to the external display device. direct memory access (dma) transfers the data transparently with minimal software intervention. bus utilization of the dma is controllable and deterministic. as cellular phone displays become larger and more colorful, demands on the processor increase. more cpu power is needed to render and manage the image. the role of the display controller is to reduce the cpu?s involvement in the transfer of data from memo ry to the display device so the cpu can concentrate on image rendering. dma is used to optimize the tr ansfer. embedded control information needed by the display device is automatically read from a second buffer in system memory and inserted into the data stream at the proper time to completely eliminate the cpu?s role in the transfer. a typical scenario for a cellular phone display is to have the display image rendered in main system memory. after the image is complete, the cpu trigge rs the slcdc module to transfer the image to the display device. image transfer is accomplished by burst dma, which steals bus cycles from the cpu. cycle-stealing behavior is programmable so bus use is kept within predefined bounds. after the transfer is complete, a maskable interrupt is generated indicating the status. fo r animated displays, it is suggested that a two-buffer ping-pong scheme be implemented so that the dma is fetching data from one buffer while the next image is rendered into the other. several display sizes and types are used in the various products that use the slcdc. the slcdc module has the capability of directly interfacing to the selected display devices. both serial and parallel interfaces are supported. the slcdc module only supports writes to the display controller. slcdc read operations from the display controller are not supported. 2.3.34 synchronous serial interface (ssi) the synchronous serial interface (ssi) is a full-duplex serial port that allows the chip to communicate with a variety of serial devices. these serial device s can be standard codecs, digital signal processors (dsps), microprocessors, peripherals, and popular i ndustry audio codecs that implement the inter-ic sound bus standard (i2s) and intel ac97 standard. the ssi is typically used to transfer samples in a periodic manner. the ssi consists of independent transmitter and receiver sections with independent clock generation and frame synchronization. the ssi contains independent (asynchronous) or shared (synchronous) transmit and receive sections with separate or shared internal/external clocks and fram e syncs, operating in master or slave mode. the ssi can work in normal mode operation using frame s ync, and in network mode operation allowing multiple devices to share the port with as many as thirty-two time slots. the ssi provides two sets of transmit and receive fifos. each of the four fifos is 8 24 bits. the two sets of tx/rx fifos can be used in network mode to provide two independent channels for transmission 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: mcimx27vop4a, mcimx27lvop4a, mcimx27mop4a, mcimx27lmop4a
