ISL12058
Low Cost and Low Power I2C-Bus Real Time Clock/Calendar Low Power and Low
Cost RTC with Alarm Function
FN6756
Rev 1.00
Dec 10, 2015
The ISL12058 device is a low power real time clock with
clock/calendar, and alarm function.
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.
