6 / 122 page  i.MX27/iMX27L Data Sheet, Advance Information, Rev. 1 6 Preliminary—Subject to Change Without Notice Freescale Semiconductor Functional Description and Application Information CSI CMOS Sensor Interface Multimedia Interface The CSI is a logic interface which enables the i.MX27/MX27L processors to connect directly to external CMOS sensors and a CCIR656 video source. 2.3.8/12 CSPI Configurable Serial Peripheral Interface (x3) Connectivity Peripheral The i.MX27/MX27L processors have three CSPI modules. CSPI is equipped with two data FIFOs and is a master/slave configurable serial peripheral interface module, allowing the i.MX27/MX27L processors to interface with both external SPI master and slave devices. 2.3.9/12 DMAC Direct Memory Access Controller Standard System Resource The DMAC of the i.MX27/MX27L processors provides 16 channels supporting linear memory, 2D memory, FIFO and end-of-burst enable FIFO transfers to support a wide variety of DMA operations. 2.3.10/13 eMMA_lt eMMA_lt H/W Accelerator Functions eMMA_lt consists of a PreProcessor and PostProcessor, and provides video acceleration. The PrP and PP can be used for generic video pre and post processing such as scaling, resizing, and color space conversions. Note: This feature is not available on MX27L. 2.3.11/13 EMI External Memory Interface Memory Interface (EMI) The EMI includes • Multi-Master Memory Interface (M3IF) • Enhanced SDRAM/MDDR memory controller (ESDRAMC) • PCMCIA memory controller (PCMCIA) • NAND Flash Controller (NFC) • Wireless External Interface Module (WEIM) — ESDRAMC Enhanced SDRAM Controller External Memory Interface The ESDRAMC provides interface and control for synchronous DRAM memories for the system. 2.3.12/15 FEC Fast Ethernet Controller Connectivity Peripheral The FEC performs the full set of IEEE Std 802.3™/Ethernet CSMA/CD media access control and channel interface functions. The FEC supports connection and functionality for the 10/100 Mbps 802.3 media independent interface (MII). It requires an external transceiver (PHY) to complete the interface to the media. 2.3.13/15 GPIO General Purpose I/O Module Pins The GPIO provides 32 bits of bidirectional, general purpose I/O. This peripheral provides dedicated general-purpose pins that can be configured as either inputs or outputs. 2.3.14/16 GPT General Purpose Timer Timer Peripheral The GPT is a multipurpose module used to measure intervals or generate periodic output. 2.3.15/16 I2C Inter IC Communicatio n Connectivity Peripheral The I2C provides serial interface to control the sensor interface and other external devices. Data rates of up to 100 Kbits/s are supported. 2.3.16/16 IIM IC Identification Module Security The IIM provides an interface for reading—and in some cases, programming, and overriding identification and control information stored in on-chip fuse elements. 2.3.17/17 JTAGC JTAG Controller Debug The JTAGC provides debug access to the ARM926 core, built-in self-test (BIST), and boundary scan test control. 2.3.18/17 Table 2.
