Low Power RTC with Battery-Backed SRAM and
Embedded Temp Compensation ±5ppm with Auto
Daylight Saving
ISL12023
The ISL12023 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.
The oscillator uses an external, low-cost 32.768kHz crystal.
The real time clock tracks time with separate registers for
hours, minutes, and seconds. The device has calendar
registers for date, month, year and day of the week. The
calendar is 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. A time stamp
function records the time and date of switchover from VDD to
VBAT power, and also from VBAT to VDD power.

NOTES:
1. Add “-T” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
