The ISL12027IB30AZ-T is an integrated circuit (IC) component developed by Renesas Electronics Corporation. It belongs to the ISL1202x family of serial real-time clocks (RTCs) that provide accurate timekeeping and calendar functions. The ISL12027IB30AZ-T offers several key features that make it suitable for a wide range of applications.
One of the notable features of the ISL12027IB30AZ-T is its high accuracy timekeeping, which allows it to maintain precise timekeeping over an extended period. It utilizes an on-chip temperature-compensated crystal oscillator (TCXO) to achieve timekeeping errors of only a few seconds per month, making it ideal for applications where accurate timekeeping is essential.
The RTC also incorporates a real-time clock counter that supports time and calendar functions. It can track time in seconds, minutes, hours, and even days, months, and years. The ISL12027IB30AZ-T supports leap year compensation and adjusts for daylight saving time (DST), ensuring accurate timing across different calendar systems.
Additionally, the ISL12027IB30AZ-T offers a wide operating voltage range of 1.8V to 3.6V, making it compatible with various power supply configurations. It also features low power consumption, with a typical current drain of only 250nA when operating in battery backup mode
