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.
