Intersil offers a selection of industry standard quartz- and
RC-based timing/oscillator ICs along with real time clocks.
Timing circuits provide clock pulsing and synchronization in
digital systems as well as pulse modulation circuits. Real
time clocks provide actual time in a digital format for
clock displays and computer systems.
Real Time Clock with Embedded Crystal, ±5ppm Accuracy
The ISL12020M device is a low power real time clock (RTC) with an embedded temperature sensor for oscillator compensation, clock/calendar, power fail, low battery monitor, brownout indicator, single periodic or polled alarms, intelligent battery backup switching, and 128 bytes of battery-backed user SRAM. The device is offered in a 20 lead DFN module that contains the RTC and an embedded 32.768kHz quartz crystal. The combined device is trimmed to provide less than ±5ppm drift over -40°C to +85°C temperature range. More
Low Power RTC with Battery-Backed SRAM and Embedded Temp Compensation ±5ppm with Auto Day Light Saving
The ISL12022 device is a low power real time clock with an embedded Temp sensor for oscillator compensation, clock/calendar, power fail, low battery monitor, brownout indicator, single periodic or polled alarms, intelligent battery backup switching, Battery Reseal™ function and 128 bytes of battery-backed user SRAM.
