5 / 110 page Functional Description and Application Information MCIMX31C/MCIMX31LC Technical Data, Rev. 4 Freescale Semiconductor 5 2.2 Module Inventory Table 3 shows an alphabetical listing of the modules in the multimedia applications processor. For extended descriptions of the modules, see the reference manual. A cross-reference is provided to the electrical specifications and timing information for each module with external signal connections. Table 2. MCIMX31C Core Core Acronym Core Name Brief Description Integrated Memory Includes ARM11 or ARM1136 ARM1136 Platform The ARM1136™ Platform consists of the ARM1136JF-S core, the ETM real-time debug modules, a 6 x 5 multi-layer AHB crossbar switch (MAX), and a Vector Floating Processor (VFP). The MCIMX31C provides a high-performance ARM11 microprocessor core and highly integrated system functions. The ARM Application Processor (AP) and other subsystems address the needs of the personal, wireless, and portable product market with integrated peripherals, advanced processor core, and power management capabilities. • 16 Kbyte Instruction Cache • 16 Kbyte Data Cache • 128 Kbyte L2 Cache • 32 Kbyte ROM • 16 Kbyte RAM Table 3. Digital and Analog Modules Block Mnemonic Block Name Functional Grouping Brief Description Section/ Page 1-Wire® 1-Wire Interface Connectivity Peripheral The 1-Wire module provides bi-directional communication between the ARM11 core and external 1-Wire devices. 4.3.4/20 ATA Advanced Technology (AT) Attachment Connectivity Peripheral The ATA block is an AT attachment host interface. It is designed to interface with IDE hard disc drives and ATAPI optical disc drives. 4.3.5/21 AUDMUX Digital Audio Multiplexer Multimedia Peripheral The AUDMUX interconnections allow multiple, simultaneous audio/voice/data flows between the ports in point-to-point or point-to-multipoint configurations. 4.3.6/30 CAMP Clock Amplifier Module Clock The CAMP converts a square wave/sinusoidal input into a rail-to-rail square wave. The output of CAMP feeds the predivider. 4.3.3/19 CCM Clock Control Module Clock The CCM provides clock, reset, and power management control for the MCIMX31C. — CSPI Configurable Serial Peripheral Interface (x 3) Connectivity Peripheral The CSPI is equipped with data FIFOs and is a master/slave configurable serial peripheral interface module, capable of interfacing to both SPI master and slave devices. 4.3.7/30 DPLL Digital Phase Lock Loop Clock The DPLLs produce high-frequency on-chip clocks with low frequency and phase jitters. Note: External clock sources provide the reference frequencies. 4.3.8/31 ECT Embedded Cross Trigger Debug The ECT is composed of three CTIs (Cross Trigger Interface) and one CTM (Cross Trigger Matrix—key in the multi-core and multi-peripheral debug strategy. — EMI External Memory Interface Memory Interface (EMI) The EMI includes • Multi-Master Memory Interface (M3IF) • Enhanced SDRAM Controller (ESDCTL) • NAND Flash Controller (NFC) • Wireless External Interface Module (WEIM) — 4.3.9.3/40, 4.3.9.1/32, 4.3.9.2/35 |
