The Diodes Incorporated PT7C43390WE is a Clock/Calendar Real Time Clock (RTC) IC featuring an I2C, 2-Wire Serial interface. This component is housed in an 8-SOIC package with a 3.90mm width. It supports both 12 and 24-hour time formats, with a YY-MM-DD-dd date format. Key features include alarm functionality, leap year compensation, and a square wave output. Timekeeping current consumption is exceptionally low, ranging from 0.6µA to 0.7µA across its 3V to 5V operating range. The device operates over a wide temperature range of -40°C to 85°C and accepts supply voltages from 1.35V to 5.5V. This RTC is commonly employed in applications requiring precise timekeeping, such as industrial control systems, consumer electronics, and automotive modules.
