The ISL12029IB27Z is a low power real-time clock and calendar IC from Quarktwin Technology Ltd. It features a clock/calendar function that tracks time in hours, minutes, and seconds, along with calendar registers for date, month, year, and day of the week, accurate through 2099 with automatic leap year correction. The device includes a power-fail indicator, clock output, and crystal compensation, utilizing an external 32.768kHz crystal oscillator. This part integrates a 512x8-bit EEPROM with 16 bytes per page, supporting single-byte write capability and a data retention of 50 years. It also offers two non-volatile alarms that can be set for various time intervals and includes intelligent battery backup switching with a low battery supply current of 800nA. The ISL12029IB27Z operates via an I¬=C interface with a data transfer rate of 400kHz and is available in a 14-lead SOIC package. Applications for this device include utility meters, HVAC equipment, audio/video components, and various networking and automation devices. It is important to note that this part is not recommended for new designs, and engineers should consider alternative options for future projects.
