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