µPD61P24
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR REMOTE CONTROL TRANSMISSION
DESCRIPTION
The µPD61P24 is a 4-bit single-chip microcontroller for infrared remote controllers for TVs, VCRs, stereos, cassette
decks, air conditioners, etc.
As the µPD61P24 is user-programmable, it is ideal for evaluation of programs running in a µPD6124A or 6600A,
and for small-scale production of such systems.
The functions of the µPD61P24 are described in detail in the following User’s Manual. Be sure to read this
manual before designing your system.
µPD612X Series User’s Manual: IEP-1083
