1 / 64 page  © 1996 DATA SHEET 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 µPD6604 is suitable for infrared remote control transmitters. For the µPD6604, we have made available the one-time PROM product µPD66P04B for program evaluation or small-quantity production. FEATURES • Program memory (ROM) : 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 fOSC = 1 MHz: RC oscillation) • Stack level : 1 level (Stack RAM is for data memory RF as well.) • I/O pins (KI/O) : 8 pins • Input pins (KI) : 4 pins • Sense input pin (S0) : 1 pin •S1/LED pin (I/O) : 1 pin (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 fOSC = 500 kHz) VDD = 2.2 to 3.6 V (when operating at fOSC = 1 MHz) • Operating ambient temperature : TA = –40 to + 85 °C • Oscillator frequency : fOSC = 300 kHz to 1 MHz • POC circuit (Mask option) APPLICATION Infrared remote control transmitter (for key-less entry) Because the µPD6604 uses an RC oscillation system clock, its accuracy and stability are lower than the models using ceramic oscillation. In applications where the clock accuracy and stability pose a problem, use the µPD6134 (ceramic oscillation type). MOS INTEGRATED CIRCUIT µPD6604 The information in this document is subject to change without notice. The mark shows major revised points.
