PD61P24
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR REMOTE CONTROL TRANSMISSION
DESCRIPTION
The
碌
PD61P24 is a 4-bit single-chip microcontroller for infrared remote controllers for TVs, VCRs, stereos, cassette
decks, air conditioners, etc.
As the
碌
PD61P24 is user-programmable, it is ideal for evaluation of programs running in a
碌
PD6124A or 6600A,
and for small-scale production of such systems.
The functions of the
碌
PD61P24 are described in detail in the following User鈥檚 Manual. Be sure to read this
manual before designing your system.
