UPD6P8 Description
The µPD6P8, 6P8A, 6P8B are microcontrollers for infrared remote control transmitters and are provided with a one-time PROM as the program memory. Because users can write programs for the µPD6P8, 6P8A, 6P8B, They are ideal for program evaluation and smallscale production of application systems that use the µPD67A, 67B, 68A, 68B. When reading this document, also refer to the following documents.
UPD6P8 Key Features
