DESCRIPTION

The µPD6P8, 6P8A, 6P8B are microcontrollers for infrared remote control transmitters and are provided with a one-time PROM as the program memory.

Because users can write programs for the µPD6P8, 6P8A, 6P8B, They are ideal for program evaluation and small-scale production of application systems that use the µPD67A, 67B, 68A, 68B.

FEATURES

• Program memory (one-time PROM): 2026 × 10 bits

• Data memory (RAM): 32 × 4 bits

• On-chip carrier generator for infrared remote control: The high-level and low-level width can be set separately from 250 ns to 64 µs (@ fX = 4 MHz operation) via modulo registers

• 9-bit programmable timer: 1 channel

• Instruction execution time: 16 µs (@ fX = 4 MHz)

• 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 pins (S0, S2): 2 units

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

• Power supply voltage: VDD = 1.9 to 3.6 V

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

• Oscillator frequency: fX = 3.5 to 4.5 MHz

• On-chip POC circuit and RAM retention detector

• On-chip oscillator (µPD6P8B)

APPLICATIONS

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