Winbond W90210/215

Time of introduction: Fall 1997

Shortly after the W89K embedded controllers Winbond introduced more sophisticated PA-RISC pro-

cessors with the W90K line of embedded controllers. The W90210F still was 32-bit PA-RISC 1.1 but

integrated many external I/O components on the chip — DRAM and DMA controllers, a PCI bridge

and various I/O ports. As its predecessor, the W90210F was a level 0 PA-RISC 1.1 implementation

without virtual addressing. It was apparently used in various “Internet appliances” : set-top boxes, TV

sets, DVD players, PDAs, VoIP devices, and for industrial automation. The W90215 is identical to the

W90210 but did not include license rights for the embedded operating system (and was thus cheaper).
