NEC V40 microprocessor familyNEC V40 is a 16-bit embedded microprocessor with 8-bit external data bus.
The processor is compatible with NEC V20 CPU,
and includes all of the V20's features: 8080 emulation, new instructions,
low-power consumption, standby mode, and others.
In addition to that it integrates many peripherals on the chip -
clock generator, timers/counters, bus interface and bus arbitration units,
asynchronous serial I/O channel, wait-state generator, DRAM refresh control
and 8-input interrupt control unit. Although the V40 has the same new
instructions that are present in Intel 80188
microprocessor, and has similar set of integrated peripherals,
it is not pin-compatible with the 80188 processor.
