64-/32-BIT MICROPROCESSOR
TM
The
µ
PD30121 (V
R
4121) is one of NEC’s V
R
Series
TM
RISC (Reduced Instruction Set Computer) microprocessors
and is a high-performance 64-/32-bit microprocessor employing the MIPS
TM
RISC architecture.
The V
R
4121 uses the high-performance, super power-saving V
R
4120
TM
as the CPU core, and has many peripheral
functions such as a DMA controller, software modem interface, serial interface, keyboard interface, IrDA interface,
touch panel interface, real-time clock, A/D converter, and D/A converter. Configured with these functions, the
V
R
4121 is suitable for high-speed battery-driven portable information systems. The external memory bus width can
be selected from 32 bits and 16 bits, realizing high-speed data transfer.
Detailed function descriptions are provided in the following user’s manual. Be sure to read it before
designing.
