DESCRIPTION

The µPD64A and 65 feature low-voltage 2.0 V operation, and incorporate a carrier generator for infrared remote control transmission, a standby release function through key entry, and a programmable timer, making them ideal for infrared remote control transmitters. A one-time PROM product, the µPD6P5 is also available for program evaluation or small-quantity production.

FEATURES

• Program memory (ROM)

• µPD64A: 1002 × 10 bits

• µPD65: 2026 × 10 bits

• Data memory (RAM): 32 × 4 bits

• On-chip carrier generator for infrared remote control

• 9-bit programmable timer: 1 channel

• Instruction execution time: 16 µs (when operating at fX = 4 MHz: ceramic oscillation)

• Stack levels: 1 (stack RAM is also used for data memory RF)

• I/O pins (KI/O): 8

• Input pins (KI): 4

• Sense input pin (S0, S2): 2

• S1/LED pin (I/O): 1 (when in output mode, this is the remote control transmission display pin.)

• Power supply voltage: VDD = 2.0 to 3.6 V

• Operating ambient temperature: TA = –40 to +85°C

• Oscillation frequency: fX = 2.4 to 8 MHz

• On-chip POC circuit

APPLICATIONS

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