ISL12026, ISL12026A

Real Time Clock/Calendar with I2C Bus™ and EEPROM

FN8231

Rev 9.00

November 30, 2010

The ISL12026 and the ISL12026A devices are micro power

real time clocks with timing and crystal compensation,

clock/calender, power-fail indicator, two periodic or polled

alarms, intelligent battery backup switching, and integrated

512x8-bit EEPROM configured in 16 Bytes per page.

Features

• Real Time Clock/Calendar

- Tracks Time in Hours, Minutes and Seconds

- Day of the Week, Day, Month and Year

- 3 Selectable Frequency Outputs

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.

• Two Non-Volatile Alarms

- Settable on the Second, Minute, Hour, Day of the Week,

Day or Month

- Repeat Mode (Periodic Interrupts)

• Automatic Backup to Battery or SuperCap

• On-Chip Oscillator Compensation

The ISL12026 and ISL12026A have different types of Power

Control Settings. The ISL12026 uses the Legacy Mode

Setting, which follows conditions set in X1226 products. The

ISL12026A uses the Standard Mode Setting. Please refer to

“Power Control Operation” on page 13 for more details. Also,

please refer to “I²C Communications During Battery Backup”

on page 22 for important details.

- Internal Feedback Resistor and Compensation

Capacitors

- 64 Position Digitally Controlled Trim Capacitor

- 6 Digital Frequency Adjustment Settings to ±30ppm

• 512x8 Bits of EEPROM

- 16-Byte Page Write Mode (32 total pages)

- 8 Modes of BlockLock™ Protection

- Single Byte Write Capability
