UPD75P316B - 4-BIT SINGLE-CHIP MICROCOMPUTER

General Description

The µPD75P316B is a product of the µPD75316B with its built-in ROM having been replaced with the onetime PROM.

It is most suitable for test production during system development and for production in small amounts since it can operate under the same supply voltage as mask products.

Key Features

  • Compatible (excluding mask option) with the µ PD75312B/75316B (mask products).
  • Memory capacity.
  • Program memory (PROM) : 16256 × 8 bits.
  • Data memory (RAM) : 1024 × 4 bits.
  • Ideal for small set as camera, etc.

DATA SHEET MOS INTEGRATED CIRCUIT µPD75P316B 4-BIT SINGLE-CHIP MICROCOMPUTER DESCRIPTION The µPD75P316B is a product of the µPD75316B with its built-in ROM having been replaced with the onetime PROM. It is most suitable for test production during system development and for production in small amounts since it can operate under the same supply voltage as mask products. The one-time PROM product is capable of writing only once and is effective for production of many kinds of sets in small quantities and early startup. The EPROM product allows programs to be written and rewritten, making it ideal for system evaluation. Functions are described in detail in the following User'S Manual, which should be read when carrying out design work.
