DATA SHEET MOS INTEGRATED CIRCUIT µPD64A, 65 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) 9-bit programmable timer Command execution time Stack level I/O pins (KI/O) Input pins (KI) Sense input pin (S0, S2) S1/LED pin (I/O) Power supply voltage Oscillator frequency POC circuit : 32 × 4 bits : 1 channel : 16 µs (when operating at fX = 4 MHz: ceramic oscillation) : 1 level (Stack RAM is for data memory RF as well.) : 8 units : 4 units : 2 units : 1 unit (When in output mode, this is the remote control transmission display pin.) : VDD = 2.0 to 3.6 V : fX = 2.4 to 8 MHz Operating ambient temperature : TA = –40 to +85 °C Built-in carrier generation circuit for infrared remote control 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.
