W90210F

The W90210F Embedded Controller is part of Winbond¢s W90K Embedded processor family. The processor is a high-performance, highly integrated 32-bit processor intended for a wide range of embedded applications, such as
set-top box, web browser, X-terminal, and visual/data communication devices..

The W90210F CPU core is based on the HP PA-RISC architecture and is upward code compatible with the W90K. The PA-RISC architecture incorporates traditional RISC elements, such as instruction pipelining, a register- oregister
instruction set and a large, general-purpose register file. Separate on-chip instruction and data caches allow the W90210F to fetch an instruction and access data in a single processor cycle.

The W90210F includes several features that greatly increase performance, reduce system component count and ease the overall system design task. In addition to its cache memories, the W90210F¢s on-chip support features  include a DRAM controller, ROM/FLASH ROM interface, PCI bridge, DMA controller, two serial ports with FIFO, IEEE 1284 parallel port, timer/counters, and enhanced debug support- all features that are commonly required in embedded
applications.
