UPD78P368A Datasheet 16/8 Bit Single-chip Microcomputer

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT mPD78P368A 16/8 BIT SINGLE-CHIP MICROPUTER The m PD78P368A is produced by replacing the internal mask ROM of the m PD78366A with a one-time PROM or EPROM. One-time PROM products, in which data can be written once are effective for manufacture of small quantities of multiple products and early stage start-up of application. EPROM products, to which programs can be re-written after previously written programs have been erased, are suited for system evaluation. The following user's manual describes the details of functions. Be sure to read it before design.

General Description

of the PROM is for both a one-time PROM and EPROM.

Document No.

Key Features

  • Compatible with the mPD78366A.
  • Can be replaced with the mPD78366A containing mask ROM on a full-production basis.
  • Internal PROM: 48K bytes.
  • Data can be written once (one-time PROM product without an erasure window).
  • Written data can be erased by exposure to ultraviolet light and re-written electrically (EPROM product with an erasure window).
  • PROM programming characteristics: Compatible with the mPD27C1001A.
  • QTOPTM microcomputer R.
