Description

The CXP402 is a CMOS 4-bit single chip microcomputer which consists of 4-bit CPU, ROM, RAM, 8-bit timer, 8-bit timer/counter, 18-bit time-base timer, LCD controller/driver, digital signal processor circuit for CD player, 1-bit DAC and the like.

Features

? Instruction cycle 1.89μs for 16.93MHz oscillation

? ROM capacity 6144 × 8 bits

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

? LCD controller/driver (Enables to direct drive)

? 8-bit timer, 8-bit timer/event counter and 18-bit time-base timer are incorporated; they are independently controllable.

? Arithmetic and logical operations between the entire RAM area, I/O area and the accumulator by means of the memory mapped I/O.

? Entire ROM area can be referred by the table lookup instruction.
