1 / 70 page  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 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.
