ARM920T CPU core supports the Thumb instruction, ARM instruction, and core debug Enhanced multiplier, JTAG, and the embedded ICE Memory Management Unit (support virtual memory) Internal AMBA bus architecture (AMBA 2.0, AHB/APB) Maximum CPU clock frequency of 200MHz@1.8V Memory Controller Little-/Big-endian support for external memory. Address space: 32Mbytes per each bank (Total 256Mbyte) Supports programmable 8/16/32-bit data bus width for each memory bank Fixed bank start address for all (static memory and dynamic memory banks) 8 memory banks - 4 memory banks for static memory (ROM, SRAM, FLASH etc) - 4 memory banks for dynamic memory (Fast Page, EDO, and Synchronous DRAM) Fully programmable access cycles for all static memory banks Supports external wait signal to extend the bus cycle Supports self-refresh mode in DRAM/SDRAM. Supports asymmetric/symmetric address of DRAM I/D (Instruction/Data) Cache Memory 64-way set-associative ICache (16KB) and DCache (16KB) 8 words per line with one valid bit and 2 dirty bits per line Pseudo-random or round-robin replacement algorithm Write-through and Write-back cache operation. The write buffer can hold 16 words of data and 4 addresses Low voltage cache for reduced power consumption Clock & Power Manager The on-chip PLL generates the necessary clock for the operation of MCU at maximum of 200MHz@1.8V Input frequency range: (Fin) = 6MHz - 10MHz. Output frequency range: (FCLK) = 20MHz - 200MHz Clock can be selectively provided to each function block by software Power Down Mode: NORMAL, SLOW, and IDLE mode - NORMAL mode: Normal operating mode - SLOW mode: Low frequency clock without PLL - IDLE mode: Clock to CPU is disabled PCI Bus Interface Embedded PC Keywords
