UPD61P24 Datasheet (NEC) - 4-BIT SINGLE-CHIP MICROCONTROLLER

UPD61P24, 4-BIT SINGLE-CHIP MICROCONTROLLER

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 syste
