DATASHEET ISL12020M Low Power RTC with Battery Backed SRAM, Integrated ±5ppm Temperature Compensation and Auto Daylight Saving FN6667 Rev 6.00 January 9, 2015 The ISL12020M 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 DFN module that contains the RTC and an embedded 32.768kHz quartz crystal. The calibrated oscillator provides less than ±5ppm drift across the 0°C to +85°C temperature range.
