ISL12028IV27Z General Description
Support is limited to customers who have already adopted these products.
The ISL12028 device is a low power real time clock with clock/calendar, power-fail indicator, clock output and crystal compensation, two periodic or polled alarms (CMOS 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 ISL12028 and ISL12028A Power Control Settings are different. The ISL12028 uses the Legacy Mode Setting, and the ISL12028A uses the Standard Mode Setting. Applications that have VBAT > VDD will require only the ISL12028A. Please refer to Power Control Operation on page 14 for more details. Also, please refer to I2C Communications During Battery Backup and LVR Operation on page 25 for important details.
