UPD61P24 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.
