UPD75112A - 4-Bit Single Chip-Microcomputer

Description

The µPD75116(A) is one of the 4-bit single-chip microcomputer 75X series.

The µPD75116(A) is a product with the extended ROM capacity of the µPD75108(A).

In addition of high-speed operations, it can manipulate data in units of 1, 4 and 8 bits.

Features

  • Higher reliability than µPD75116.
  • Architecture "75X" equivalent to 8-bit microcomputer.
  • Minimum instruction execution time (high-speed operation): 0.95 µs (when operated at 4.19 MHz and 5 V).
  • Instruction execution variable function: 0.95µs/1.91µs/ 15.3 µs (when operated at 4.19 MHz).
  • Many input/output ports: 58.
  • 3-channel on-chip 8-bit timers.
  • 8-bit on-chip serial interface.
  • Multi-interruptible vector interrupt function Ap.

µPD75112(A), 75116(A) 4-Bit Single Chip-Microcomputer Data Sheet Description The µPD75116(A) is one of the 4-bit single-chip microcomputer 75X series. The µPD75116(A) is a product with the extended ROM capacity of the µPD75108(A). In addition of high-speed operations, it can manipulate data in units of 1, 4 and 8 bits. In particular, the I/O operation of the µPD75116 have been improved by a wide variety of bit control instructions. The µPD75116 is provided with interface inputs/outputs with peripheral circuits having different power voltages, and analog inputs and suitable for controlling automobile electrical equipment, etc. For the µPD75116(A), an on-chip pin-compatible one-time PROM product (µPD75P116) is separately available for system development evaluation.
