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.
• Internal memory
• Program memory (ROM) : 8068 × 8 bits (µ PD75108) : 6016 × 8 bits (µ PD75106) : 4096 × 8 bits (µ PD75104)
• 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.
