4-BIT SINGLE-CHIP MICROCOMPUTER
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.
Equipped with I/Os for interfacing with peripheral circuits operating on a different supply
voltage, outputs that can directly drive LEDs, and analog inputs, µPD75108 is suitable for controlling...
