UPD75212A Datasheet 4-bit Single-chip Microcomputer

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD75212A 4-BIT SINGLE-CHIP.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The µPD75212A is a microputer with a CPU capable of 1-, 4-, and 8-bit data processing, ROM, RAM, I/O ports, a fluorescent display tube controller/driver, a watch timer, a timer/pulse generator capable of outputting 14-bit PWM, a serial interface and a vectored interrupt function integrated on a single-chip.

The µPD75212A is a version of the µ PD75216A with a small ROM capacity (12K).

The µPD75212A uses the VCR, ECR and CD fluorescent display tubes as display devices and is most suitable for applications requiring the timer/watch function and high-speed interrupt servicing.

Key Features

  • Architecture equal to that of an 8-bit microcomputer High-speed operation : Minimum instruction execution time : 0.95 µs (when operated at 4.19 MHz) Instruction execution time variable function realizing a wide range of operating voltages On-chip large-capacity program memory : 12K bytes.
  • Watch operation with an ultra low current consumption : 5 µA TYP. (at the 3 V operation).
  • On-chip programmable fluorescent display tube controller/driv.
