Real Time Clock/Calendar with Event Detection
Data Sheet
September 27, 2005
FN6109.1
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.

*Add “-TK” suffix for tape and reel.
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.
