UPD17P204 Datasheet (NEC) - 4-BIT SINGLE-CHIP MICROCONTROLLER WITH STATIC RAM AND 3-CHANNEL TIMER FOR INFRARED REMOTE CONTROLLER

UPD17P204, 4-BIT SINGLE-CHIP MICROCONTROLLER WITH STATIC RAM AND 3-CHANNEL TIMER FOR INFRARED REMOTE CONTROLLER

µPD17P203A and µPD17P204 are variations of µPD17203A and µPD17204 respectively and are equipped with a one-time PROM instead of an internal mask ROM.

µPD17P203A and µPD17P204 are suitable for evaluating a program when developing µPD17203A and µPD17204 systems respectively because the program can be
