Low Power RTC with Battery Backed SRAM, Integrated
±5ppm Temperature Compensation and Auto Daylight
Saving
ISL12020M
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.
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.
