General Description

µPD75108 is a 4-bit single-chip microcomputer integrating timer/event counters, serial interface, and vector interrupt function, in addition to a CPU, ROM, RAM, and I/O ports, on a single chip.

Operating at high speeds, the microcomputer allows data to be manipulated in units of 1, 4, or 8 bits.

In addition, various bit manipulation instructions are provided to reinforce I/O manipulation capability.

Key Features

Internal memory.
Program memory (ROM) : 8068 × 8 bits (µ PD75108) : 6016 × 8 bits (µ PD75106) : 4096 × 8 bits (µ PD75104).
Data memory (RAM) : 512 × 4 bits ( µPD75108) : 320 × 4 bits ( µPD75106, 75104).
New architecture “75X series” rivaling 8-bit microcomputers.
43 systematically organized instructions.
A wealth of bit manipulation instructions.
8-bit data transfer, compare, operation, increment, and decrement instructions.
