MOS INTEGRATED CIRCUIT
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
FEATURES
Internal memory
• Program memory (ROM)
: 8064 × 8 bits (µPD75108A)

: 320 × 4 bits (µPD75104A)
Architecture “75X” rivaling 8-bit microcomputers
43 systematically organized instructions
• A wealth of bit manipulation instructions
• 8-bit data transfer, compare, operation, increment, and decrement instructions
• 1-byte relative branch instructions
• GETI instruction executing 2-/3-byte instruction with one byte
High speed. Minimum instruction execution time: 0.95 µs (at 4.19 MHz, 5V)
Instruction execution time change function: 0.95 µs/1.91 µs/15.3 µs (at 4.19 MHz)
I/O port pins as many as 58
Three channels of 8-bit timers
8-bit serial interface
Multiplexed vector interrupt function
Unless there are differences among µPD75104A and 75108A functions, µPD75108A is treated as the
representative model throughout this manual.
The information in this document is subject to change without notice.
