The Diodes Incorporated PT7C43390LE is a highly accurate Real Time Clock (RTC) IC supporting both clock and calendar functions. This component features a 2-wire serial interface (I2C) for efficient communication and is housed in an 8-MSOP package. It offers precise timekeeping with a low current consumption of typically 0.65µA to 0.7µA across its 1.3V to 5.5V operating voltage range. Key features include alarm functionality, leap year compensation, and a square wave output. The date format is YY-MM-DD-dd, and the time format supports both 12/24-hour modes. This device is suitable for surface mount applications and operates reliably within a temperature range of -40°C to 85°C. Its capabilities make it a valuable component in industrial control, consumer electronics, and battery-backed systems requiring accurate timekeeping.
