ISL12022M Product details

Low Power RTC with Battery Backed SRAM, Integrated ±5ppm Temperature Compensation, and Auto Daylight Saving



The ISL12022M device is a low power real time clock (RTC) with an embedded temperature sensor and crystal. Device functions include oscillator compensation, clock/calendar, power fail and low battery monitors, brownout indicator, one-time, periodic or polled alarms, intelligent battery backup switching, Battery Reseal™ function and 128 bytes of battery-backed user SRAM. The device is offered in a 20 Ld SOIC module that contains the RTC and an embedded 32.768kHz quartz crystal. The calibrated oscillator provides less than ±5ppm drift over the full -40°C to +85°C temperature range.
