Renesas Electronics Corporation's ISL1221IUZ is a Time Event Recorder Real Time Clock (RTC) IC. This device features a 2-wire serial interface, specifically I2C, for communication. It offers robust timekeeping with a low current draw, typically 4µA to 6µA across its 3V to 5V operating range. The ISL1221IUZ supports both 12/24 hour time formats (HH:MM:SS) and a YY-MM-DD-dd date format. Integrated features include alarm functionality, leap year compensation, and 2 bytes of SRAM for user data storage. Designed for surface mount applications, it is housed in a compact 10-MSOP package. This component is suitable for use in various industrial and consumer electronics applications requiring accurate timekeeping and event logging. The operating temperature range is -40°C to 85°C.
