NEC V50 is a 16-bit embedded microprocessor compatible with
NEC V30. The V50 has all of the features of the
V30 - 8080 emulation, new instructions, low-power consumption, standby mode,
and others. At the same time it integrates many peripherals on the chip -
clock generator, DRAM refresh control, timers/counters, bus interface and
bus arbitration units, asynchronous serial I/O channel, wait-state generator
and 8-input interrupt control unit. Even though the V50 has the same new
instructions that are present in Intel 80186
CPU, and has similar set of integrated peripherals,
it is not pin-compatible with the 80186 microprocessor.
