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 small quantity 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 : 1 channel

• Command execution time : 8 µs (when operating at fX = 8 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) : 1 unit

• S1/LED pin (I/O) : 1 unit (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 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 : fX = 2.4 to 8 MHz

• POC circuit (Mask option)

APPLICATION

Infrared remote control transmitter (for AV and household electric appliances)
