4-BIT SINGLE-CHIP MICROCONTROLLER FOR INFRARED REMOTE CONTROL TRANSMISSION

The μPD6P5 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 μPD6P5, it is ideal for program evaluation and small-scale production of the application systems using the μPD64A or 65.

FEATURES

? Program memory (one-time PROM) : 2,026 × 10 bits

? Data memory (RAM) : 32 × 4 bits

? Built-in carrier generation circuit for infrared remote control

? 9-bit programmable timer : 1 channel

? Command execution time : 16 μs (when operating at fX = 4 MHz: ceramic oscillation)

? Stack level : 1 level (Stack RAM is for data memory RF as well.)

? I/O pins (KI/O) : 8 units

? Input pins (KI) : 4 units

? Sense input pin (S0, S2) : 2 units

? S1/LED pin (I/O) : 1 unit (In output mode, this is the remote control transmission display pin.)

? Power supply voltage : VDD = 2.2 to 3.6 V

? Operating ambient temperature : TA = –40 to +85 °C

? Oscillator frequency : fX = 2.4 to 4.8 MHz

? POC circuit

APPLICATION

Infrared remote control transmitter (for AV and household electric appliances)
