UPD75518A - 4 BIT SINGLE-CHIP MICROCOMPUTER

Download the UPD75518A datasheet PDF. This datasheet also covers the UPD75518 variant, as both devices belong to the same 4 bit single-chip microcomputer family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Higher reliable than the µPD75518.
  • Capacities of program memory, ROM: 32640 × 8 bits.
  • Capacity of data memory, RAM: 1024 × 4 bits.
  • Function for specifying the instruction execution time (useful for high-speed operation and saving power).
  • 0.67 µs/1.33 µs/2.67 µs/10.7 µs (when the main system clock operates at 6.0 MHz).
  • 0.95 µs/1.91 µs/3.82 µs/15.3 µs (when the main system clock oper.

ELECTRON DEVICE DATA SHEET MOS INTEGRATED CIRCUIT µPD75518(A) 4 BIT SINGLE-CHIP MICROCOMPUTER The µPD75518(A) is a 75X series four-bit single-chip microcomputer which enables data processing equivalent to that performed by an eight-bit microcomputer. It is a high-performance product, whose minimum instruction execution time is 0.67 µs, shorter than 0.95 µs for the conventional µPD75516. The ROM and RAM capacities are also larger, and the throughput of the 75X series is further increased. The µPD75517(A) is suited to controllers of electric parts of automobiles.
