Краткое описание:
Ultra-Small, Ultra-Low Power 1 Hz – 32.768 kHz Programmable Oscillator
Дополнительная информация
Programmable MEMS oscillator factory set to a 256 Hz output in a 2.0 x 1.2 mm SMD package. This orderable device is specified for ±100 ppm frequency stability over -40°C to +85°C and uses a reduced-swing 400 mV output with 1.10 V VOH. It operates from a 1.2 V to 3.63 V supply, with typical core current of 0.9 µA at 1.8 V and 25°C. The oscillator eliminates external load capacitors and is intended for low-frequency timing functions such as RTC reference clocks and pulse-per-second timekeeping.
