Datasheet Summary
Powered by GS/AI

The ISL12023IVZ is a low power real-time clock (RTC) from Quarktwin Technology Ltd. designed for various applications including utility meters, POS equipment, medical devices, and security systems. It features an embedded temperature sensor for oscillator compensation, a clock/calendar function with registers for hours, minutes, seconds, and date information accurate through 2099, including automatic leap year correction. The device supports automatic Daylight Saving Time adjustments and includes a battery-backed SRAM of 128 bytes. The ISL12023IVZ operates with a supply voltage range of 2.7V to 5.5V and can function in temperatures from -40¬8C to +85¬8C. It utilizes an external 32.768kHz crystal oscillator and provides a time stamp function for power switchover events. The device also includes user-selectable power fail and battery monitors, a low voltage reset feature, and a single alarm that can be configured for various time settings. The I2C interface supports a clock frequency of up to 400kHz, and the device is packaged in a 14-lead TSSOP format. This product is not recommended for new designs, and there is no recommended replacement available.
