The VRC4172^TMcompanion chip to NEC’s VR4121^TMMIPS^®RISC microprocessor is designed for high-end

Windows CE Handheld PC Professional applications. The VR4121 microprocessor functions as the host

CPU, while the VRC4172 supplies the SDRAM interface, USB interface, host- and peripheral-selectable

IEEE-1284 parallel interface, 16550-compliant serial interface, PS/ 2 interface, general-purpose I/ O ports,

general-purpose chip select signal, and pulse-width modulation for the LCD back light.

In combination, the VR4121 and VRC4172 offer an excellent performance/ cost solution for next-generation

Windows CE applications, forming a superior engine for most, if not all, high-performance Windows

CE-based handheld products.
