UPD178P018A - 8-BIT SINGLE-CHIP MICROCONTROLLER

Datasheet Summary

Description

The µ PD178P018ANote is a device in which the internal mask ROM of the µ PD178018A is replaced with a onetime PROM or EPROM.

Because this device can be programmed by users, it is ideally suited for system evaluation, small-lot and multipledevice production, and early development and time-to-market.

Features

  • Pin-compatible with mask ROM version (except for VPP pin).
  • Internal PROM: 60 Kbytes.
  • µPD178P018AGC : One-time programmable (ideally suited for small-lot production).
  • µPD178P018AKK-T : Reprogrammable (ideally suited for system evaluation).
  • Internal high-speed RAM: 1 024 bytes.
  • Internal expansion RAM: 2 048 bytes.
  • Buffer RAM: 32 bytes.
  • Can be operated in the same power supply voltage as the mask ROM version (During PLL operat.

PRELIMINARY DATA SHEET MOS INTEGRATED CIRCUIT µ PD178P018A 8-BIT SINGLE-CHIP MICROCONTROLLER DESCRIPTION The µ PD178P018ANote is a device in which the internal mask ROM of the µ PD178018A is replaced with a onetime PROM or EPROM. Because this device can be programmed by users, it is ideally suited for system evaluation, small-lot and multipledevice production, and early development and time-to-market. The µ PD178P018A is a PROM version corresponding to the µPD178004A, 178006A, and 178016A. Note Caution Under development The µ PD178P018AKK-T does not maintain planned reliability when used in your system’s massproduced products. Please use only experimentally or for evaluation purposes during trial manufacture. For more information on functions, refer to the following User’s Manuals.
