ISL12020MIRZ

INTERSIL  ISL12020MIRZ  芯片, 实时时钟, 星期-日-月-年, 128 X 8, DFN-20

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 over the full -40°C to +85°C temperature range.
