The ISL12022MA 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. Backup battery current draw is less than 1. 6µA over the temperature range. 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. The RTC tracks time with separate registers for hours, minutes, and seconds. The calendar registers track date, month, year and day of the week and are accurate through 2099, with automatic leap year correction. Daylight Savings time adjustment is done automatically, using parameters entered by the user. Power fail and battery monitors offer user-selectable trip levels. The time stamp function records the time and date of switchover from VDD to VBAT power, and also from VBAT to VDD power. The ISL12022MA features enhanced immunity to ESD per the IEC61000-4-2 standard, and also provides improved resistance to system leakage related to environmental moisture.
