17 / 32 page ![]() µPD17P236 17 Data Sheet U14776EJ1V0DS00 Recommended Operating Ranges (TA = –40 to +85 °C, VDD = 2.2 to 3.6 V) Item Symbol Conditions MIN. TYP. MAX. Unit Supply voltage VDD1 fX = 1 MHz High-speed mode 2.2 3.6 V (Instruction execution time: 16 µs) VDD2 fX = 4 MHz High-speed mode (Instruction execution time: 4 µs) VDD3 fX = 8 MHz Ordinary mode (Instruction execution time: 4 µs) VDD4 High-speed mode 3.0 3.6 V (Instruction execution time: 2 µs) Oscillation frequency fX 1.0 4.0 8.0 MHz Operating temperature TA –40 +25 +85 °C Low-voltage detector circuit Note tCY 432 µs Note Reset if the status of VDD = 2.05 V (TYP.) lasts for 1 ms or longer. Program hang-up does not occur even if the voltage drops, until the reset function is effected. Some oscillators stop oscillating before the reset function is effected. fX vs VDD Supply voltage: VDD (V) 0.4 2 1 3 4 5 6 7 8 9 10 2 0 2.2 3 3.6 4 (MHZ) Operation guaranteed area Remark The region indicated by the broken line in the above figure is the guaranteed operating range in the high- speed mode. |
