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)
