companion chip to NEC’s V
R
4121
TM
MIPS
RISC microprocessor is designed for high-end
Windows
CE Handheld PC Professional applications. The V
R
4121 microprocessor functions as the host
CPU, while the V
RC
4172 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 V
R
4121 and V
RC
4172 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.
