UPD75P036 - 4-BIT SINGLE-CHIP MICROCONTROLLER

General Description

The µ PD75P036 is a 4-bit signgle-chip microcontroller that replaced the µ PD75028's on-chip ROM with one-time PROM or EPROM.

Because this device can operate at the same supply voltage as its mask version, it is suited for preproduction in development stage or small-scale production.

Key Features

  • µ PD75028 compatible.
  • At full production, the µ PD75P036 can be replaced with the µ PD75028 which incorporates mask ROM Memory capacity.
  • Program memory (PROM): 16256 x 8 bits.
  • Data memory (RAM): 1024 x 4 bits.
  • Internal pull-up resistors can be specified by software: Ports 0-3, 6-8 Internal pull-down resistors can be specified by software: Port 9 Open-drain input/output: Ports 4, 5, 10 Can operate at low vol.

DATA SHEET MOS Integrated Circuit µPD75P036 4-BIT SINGLE-CHIP MICROCONTROLLER DESCRIPTION The µ PD75P036 is a 4-bit signgle-chip microcontroller that replaced the µ PD75028's on-chip ROM with one-time PROM or EPROM. Because this device can operate at the same supply voltage as its mask version, it is suited for preproduction in development stage or small-scale production. The one-time PROM version is programmable only once and is useful for small-scale production of many different products and time-to-market of a new product. The EPROM version is programmable, erasable, and reprogrammable, and is suited for the evaluation of application systems. Detailed functions are described in the followig user's manual. Be sure to read it for designing.
