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)
