UPD6126A Datasheet 4-bit Single Chip Microcontroller

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET µ PD6125A, 6126A 4-BIT SINGLE CHIP MICROCONTROLLER FOR REMOTE CONTROL TRANSMISSION MOS INTEGRATED.

General Description

The µPD6125A and 6126A are 4-bit single-chip microcontrollers for infrared remote controllers for TVs, VCRs, stereos, cassette decks, air conditioners, etc.

These microcontrollers consist of ROM, RAM, a 4-bit parallel-processing ALU, a programmable timer, key input/ output ports, and transmit output ports.

Functioning is controlled in software.

Key Features

  • Transmitter for programmable infrared remote controller 19 types of instructions Instruction execution time: ceramic oscillator) 17.6 µs (with 455-kHz.
  • Transmission-in-progress indication pin (S-OUT): 1 pin Transmit carrier frequency (REM) fOSC/12, fOSC/8 Standby operation (HALT/STOP mode) Low power consumption Current consumption in STOP mode (TA = 25°C) 1 µA MAX. Low-voltage operation: VDD = 2.0 to 6.0 V.
