Overview
DATA SHEET MOS INTEGRATED CIRCUIT µPD61P34B 4-BIT SINGLE-CHIP MICROCONTROLLER FOR INFRARED REMOTE CONTROL TRANSMISSION DESCRIPTION The µPD61P34B is a microcontroller for infrared remote control transmitters which is provided with a one-time PROM as the program memory.
Because users can write programs for the µPD61P34B, it is ideal for program evaluation and small-scale production of the application systems using the µPD6133 or 6134.
When reading this document, also refer to the µPD6133, 6134 Data Sheet (U10454E).
FEATURES • Program memory (one-time PROM) : 1002 × 10 bits • Data memory (RAM) • 9-bit programmable timer • Command execution time • Stack level • I/O pins (KI/O) • Input pins (KI) • Sense input pin (S0) • S1/LED pin (I/O) • Power supply voltage • Operating ambient temperature • Oscillator frequency • POC circuit : 32 × 4 bits : 1 channel : 16 µs (when operating at fX = 500 kHz: ceramic oscillation) : 1 level (Stack RAM is for data memory RF as well.
) : 8 units : 4 units ...
