FEATURES

? Program memory (one-time PROM): 4074 × 10 bits

? Data memory (RAM): 128 × 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) (μPD6P9M1)

8 μs (@ fX = 4 MHz) (μPD6P9M3)

? 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 = 2.2 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

? Capacitor for oscillator: Not available
