DESCRIPTION
The
μ
PD30101 (V
R
4101) is one of NEC’s V
R
series RISC (Reduced Instruction Set Computer) microprocessors and
is a high-performance 64-bit microprocessor employing the MIPS RISC architecture.
The V
R
4101 is ideal for applications in battery-driven, high-performance portable information systems. This
microprocessor uses the high-performance, super power-saving V
R
4100 as the CPU core, and has many peripheral
circuits such as DMA, serial interface, keyboard interface, IrDA interface, touch panel interface, and real-time clock.
The functions of the V
R
4101 are explained in detail in the following manual. Be sure to refer to this manual
when designing your system.
