ISL12029, ISL12029A
Real Time Clock/Calendar with I2C Bus
and EEPROM
The ISL12029 device is a low power real time clock with
clock/calendar, power-fail indicator, clock output and crystal
compensation, two periodic or polled alarms (open drain
output), intelligent battery backup switching, CPU
Supervisor, integrated 512x8-bit EEPROM configured in 16
bytes per page.
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.
The ISL12029 and ISL12029A Power Control Settings are
different. The ISL12029 uses the Legacy Mode Setting, and
the ISL12029A uses the Standard Mode Setting.
Applications that have VBAT > VDD will require only the
ISL12029A. Please refer to “Power Control Operation” on
page 14 for more details. Also, please refer to “I2C
Communications During Battery Backup” on page 24 for
important details.
