ISL12027, ISL12027A
Real Time Clock/Calendar with EEPROM
The ISL12027 device is a low power real time clock with
timing and crystal compensation, clock/calender, power-fail
indicator, two periodic or polled alarms, intelligent battery
backup switching, CPU Supervisor and integrated 512x8-bit
EEPROM, in 16 Byte per page format.
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 ISL12027 and ISL12027A Power Control Settings are
different. The ISL12027 uses the Legacy Mode Setting, and
the ISL12027A uses the Standard Mode Setting.
Applications that have VBAT > VDD will require only the
ISL12027A. Please refer to“Power Control Operation” on
page 15 for more details. Also, please refer to “I2C
Communications During Battery Backup and LVR Operation”
on page 24 for important details.
