UPD6P8 Overview
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
- Program memory (one-time PROM): 2026 × 10 bits

- On-chip carrier generator for infrared remote control: The high-level and low-level width can be set separately from 250
- 9-bit programmable timer: 1 channel
- Instruction execution time: 16 µs (@ fX = 4 MHz)
- Stack level: 1 level (stack RAM is for data memory RF as well)
- I/O pins (KI/O): 8 units 4 units
- Input pins (KI): 2 units
- Sense input pins (S0, S2)
- S1/LED pin (I/O): 1 unit (when in output mode, this is the remote control transmission display pin)
