µPD75104A, 75108A
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
µPD75108A is a 4-bit single-chip CMOS microcomputer having a data processing capability comparable to
that of an 8-bit microcomputer. 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, µPD75108A is suitable for controlling
such small equipments as cameras and VCRs.
Detailed functions are described in the following user’s manual. Be sure to read it for designing.
µPD751XX Series User’s Manual: IEM-922
