ISL12027, ISL12027A Real Time Clock/Calendar with EEPROM DATASHEET

PublishTime：2020-04-30

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.
