32-BITCMOSMICROCONTROLLER
FEATUR*
Architecture
? Integrated system for hand-held devices and
general embedded applications.
? 16/32-Bit RISC architecture and powerful
instruction set with ARM920T CPU core.
? Enhanced ARM architecture MMU to support
WinCE, EPOC 32 and Linux.
? Instruction cache, data cache, write buffer and
Physical address TAG RAM to reduce the effect of
main memory bandwidth and latency on
performance.
? ARM920T CPU core supports the ARM debug
architecture.
? Internal Advanced Microcontroller Bus Architecture
(A*A) (A*A2.0, AHB/APB).
NAND Flash Boot Loader
? Supports booting from NAND flash memory.
? 4KB internal buffer for booting.
? Supports storage memory for NAND flash memory
after booting.
? Supports Advanced NAND flash
Cache Memory
? 64-way set-*ociative cache with I-Cache (16KB)
and D-Cache (16KB).
? 8words length per line with one valid bit and two
dirty bits per line.
? Pseudo random or round robin replacement
algorithm.
? Write-through or write-back cache operation to
update the main memory.
? The write buffer can hold 16 words of data and four
addresses.
