Overview: DATASHEET ISL12024IRTC
Real-Time Clock/Calendar with Embedded Unique ID FN6749 Rev 1.00 December 15, 2011 The ISL12024IRTCZ device is a micro-power real-time clock with embedded 64-bit unique ID, timing and crystal pensation, 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.
The device contains a 64-bit unique ID number for security and product identification applications. It is housed in a tiny 3mmx3mm TDFN package for small handheld applications. The clock output defaults to 32.768kHz on initial power-up for low power microcontroller clocking applications. The low 800nA battery supply current extends backup battery life.
