1 Overview
The W90P710 16/32-bit RISC micro-controller is a cost-effective, high-performance micro-controller
solution for Ethernet-based system. An integrated Ethernet controller, the W90P710, is designed for
use in managed communication hubs and routers.
The W90P710 is built around an outstanding CPU core: on the 16/32 ARM7TDMI based RISC
processor designed by Advanced RISC Machines, Ltd. The ARM7TDMI core is a low power, general-
purpose integrated circuits. Its simple, elegant, and fully static design is particularly suitable for cost-
sensitive and power-sensitive applications.
The W90P710 offers a 4K-byte I-cache/SRAM, a 4K-byte D-cache/SRAM and one MACs of
Ethernet controller that reduces total system cost. A color LCD controller is built in to support black-and-
white/gray-level/color TFT and low cost STN LCD modules. Most of the on-chip function blocks have
been designed using an HDL synthesizer and the W90P710 has been fully verified in Winbond’s state-
of-the art ASIC test environment.
The other important peripheral functions include one USB host controller, one USB device
controller, one AC97/IIS codec controller, one SD/SDIO host controller, one 2-Channel GDMA, two
smartcard host controller, four independent UARTS, one Watchdog timer, two 24-bit timers with 8-bit
pre-scale, 71 programmable I/O ports, PS/2 keyboard controller and an advance interrupt controller.
The external bus interface (EBI) controller provides for SDRAM, ROM/SRAM, flash memory and I/O
devices. The System Manager includes an internal 32-bit system bus arbiter and a PLL clock controller.
