UPD17226 Datasheet 4-bit Single-chip Microcontroller

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD17225, 17226, 17227, 17228 4-BIT SINGLE-CHIP MICROCONTROLLER FOR SMALL GENERAL-PURPOSE INFRARED REMOTE CONTROL.

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

General Description

µPD17225, 17226, 17227, 17228 (hereafter called µPD17225 subseries) are 4-bit single-chip microcontrollers for small general-purpose infrared remote control transmitters.

It employs a 17K architecture of general-purpose register type devices for the CPU, and can directly execute operations between memories instead of the conventional method of executing operations through the accumulator.

Moreover, all the instructions are 16-bit 1-word instructions which can be programmed efficiently.
