1 / 64 page 4-BIT SINGLE-CHIP MICROCONTROLLER FOR INFRARED REMOTE CONTROL TRANSMISSION DESCRIPTION Equipped with low-voltage 2.0 V operation, a carrier generation circuit for infrared remote control transmission, a standby release function through key entry, and a programmable timer, the µPD64A and 65 are suitable for infrared remote control transmitters. For the µPD64A and 65, we have made available the one-time PROM product µPD6P5 (under development) for program evaluation or small-quantity production. FEATURES • Program memory (ROM) • µPD64A : 1002 × 10 bits • µPD65 : 2026 × 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 (When in output mode, this is the remote control transmission display pin.) • Power supply voltage : VDD = 2.0 to 3.6 V • Operating ambient temperature : TA = –40 to +85 °C • Oscillator frequency : fX = 2.4 to 8 MHz • POC circuit APPLICATION Infrared remote control transmitter (for AV and household electric appliances) Unless otherwise specified, the µPD65 is treated as the representative model throughout this document.
