DATA SHEET µPD6124A, 6600A 4-BIT SINGLE-CHIP MICROCONTROLLER FOR REMOTE CONTROL TRANSMISSION MOS INTEGRATED CIRCUIT DESCRIPTION The µPD6124A and 6600A are 4-bit single-chip microcontrollers for infrared remote controllers for TVs, VCRs, stereos, cassette decks, air conditions, 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 by a program.
A one-time PROM, model µPD61P24, to which a program can be written only once is also available.
This one-time PROM is ideal for evaluation of programs running in a µPD6124A or 6600A, and for small-scale production of such s...
