DATA SHEET MOS INTEGRATED CIRCUIT µPD75104, 75106, 75108 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 such systems as VTRs, acoustic products, button telephones, radio communications equipment, and printers. A pin-compatible EPROM model is also available for evaluation of system development and small-scale production of application systems. Detailed functions are described i [ … ]
