UPD75108 Product details

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 volta
