Description

CXP5080 is a CMOS 4-bit single chip microcomputer of piggyback/evaluator combined type which has been developed for functional evaluation of the CXP5084/5086.

Features

? Instruction cycle 3.8μs/4.19MHz (CXP5080) 1.9μs/4.19MHz (CXP5080H)

? ROM capacity Maximum 8K bytes (EPROM 27C64, LCC/DIP type 27C64)

? RAM capacity 400 × 4 bits (Including stack, display area)

? 32 general purpose I/O ports

? 16 large current output ports

? LCD controller/driver (Enables to direct drive)

— Enables to specify the segment output of 24, 20 and 16 optionally

— Enables to select program of the duty, 1/2, 1/3 and 1/4
