1 / 68 page  The mark shows major revised points. 4-BIT SINGLE-CHIP MICROCONTROLLER FOR INFRARED REMOTE CONTROL TRANSMISSION 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 : 1 channel • Command execution time : 8 µs (when operating at fX = 8 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) : 1 unit •S1/LED pin (I/O) : 1 unit (When in output mode, this is the remote control transmission display pin.) • Power supply voltage : VDD = 1.8 to 3.6 V (when operating at fX = 4 MHz) VDD = 2.2 to 3.6 V (when operating at fX = 8 MHz) • Operating ambient temperature : TA = –40 to +85 ˚C • Oscillator frequency : fX = 2.4 to 8 MHz • POC circuit (Mask option) 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.
