K4 Family Product Brief
Description
The μPD7842xx devices are highly integrated members of NEC’s K4 family of 16-bit
microcontrollers whose expanded memory and higher performance provide an
upward migration path for NEC’s 8-bit K0 microcontrollers. With the same peripherals
and instruction set, and an address space expanded to 1M, the μPD7842xx makes it
easy to add features to any existing K0 design. The minimum instruction execution
time is reduced from 0.4 μs to 0.16 μs, and RAM/ROM options are increased to allow
up to 256K ROM and 12K RAM on chip. Dual oscillators, 1.8- to 5.5-volt operation,
and powerful power-saving modes combine to make this family ideal in consumer
electronics applications requiring high integration and very low cost.
The μPD7842xx is supported by an extensive tool chain that includes a software
simulator, C compiler, relocatable assembler, screen debugger and in-circuit
emulator. These tools are compatible throughout NEC’s K Series product line.
