Low Power RTC with Battery Backed
SRAM and Event Detection
The ISL1209 device is a low power real time clock with event
detect function, timing and crystal compensation,
clock/calendar, power fail indicator, periodic or polled alarm,
intelligent battery backup switching and battery-backed user
SRAM.
NOTE: 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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are 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.
