Designed around the popular MIPS
RISC architecture, the V
R
4111
(μPD30111) offers excellent power
consumption and outstanding perfor-
mance in a high-integration, low-cost
microprocessor. This processor is
the first NEC device to use the ultra-
low power-consuming V
R
4110
CPU
core based on NEC’s advanced 0.25-
micron technology. The V
R
4111 is
compatible with MIPS I, II, III and
MIPS16 instruction set architectures.
The high speed, compact size, low
power consumption and feature-rich,
on-chip integration of the V
R
4111
make it ideal for use in embedded,
handheld or stationary consumer applications.
