UPD62

DATA SHEET MOS INTEGRATED CIRCUIT µPD62 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 µPD62 is suitable for infrared remote control transmitters. For the µPD62, we have made available the one-time PROM product µPD6P4B for program evaluation or smallquantity production. FEATURES Program memory (ROM): 512 × 10 bits Data memory (RAM): 32 × 4 bits Built-in carrier generation circuit for infrared remote control 9-bit programmable timer Command 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 fX = 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 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 POC circuit (Mask option) : fX = 2.4 to 8 MHz APPLICATION Infrared remote control transmitter (for AV and household electric appliances) The information in this document is subject to change without notice.
