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
www.DataSchoemet4mUu.cnoimcations 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 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)
: 8068 × 8 bits (µPD75108)
: 6016 × 8 bits (µPD75106)
: 4096 × 8 bits (µPD75104)
• Data memory (RAM)
: 512 × 4 bits (µPD75108)
: 320 × 4 bits (µPD75106, 75104)
New architecture “75X series” 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), 5 V
Power-saving, instruction 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
Model with PROM is available: µPD75P108B (One-time PROM, EPROM)
Unless there are differences among µPD75104, 75106, and 75108 functions, µPD75108 is treated as the
representative model throughout this manual.
