DATA SHEET µPD63, 63A, 64 4-BIT SINGLE-CHIP MICROCONTROLLER FOR INFRARED REMOTE CONTROL TRANSMISSION MOS INTEGRATED CIRCUIT DESCRIPTION Equipped with low-voltage 1.8 V operation, a carrier generation circuit for infrared remote control transmission, a standby release function through key entry, and a programmable timer, the µPD63, 63A, and 64 are suitable for infrared remote control transmitters. For the µPD63, 63A and 64, we have made available the one-time PROM product µPD6P4B for program evaluation or small-quantity production. Features - Program memory (ROM) - µPD63 : 512 × 10 bits - µPD63A: 768 × 10 bits - µPD64 : 1002 × 10 bits - Data memory (RAM): 32 × 4 bits - Built-in carrier generation circuit for infrared remote control - 9-bit programmable timer - mand execution time - Stack level - I/O pins (KI/O) - Input pins (KI) - Sense input pin (S0) - S1/LED pin (I/O) - Power supply voltage : 1 channel : 8 µs (when operating at f X = 8 MHz: ceramic oscillation) : 1 level (Stack RAM is for data memory RF as well.) : 8 units : 4 units : 1 unit : 1 unit (When in output mode, this is the remote control transmission display pin.) : VDD = 1.8 to 3.6 V (when operating at f X = 4 MHz) VDD = 2.2 to 3.6 V (when operating at f X = 8 MHz) - Operating ambient temperature : TA = - 40 to +85 ˚C - Oscillator frequency - POC circuit (Mask option) : f X = 2.4 to 8 MHz APPLICATION Infrared remote control transmitter (for AV and household electric appliances) Unless otherwise stated, the µPD63 is taken as a representative product in this document.
