The Diodes Incorporated PT7C4302ZEE is a Real Time Clock (RTC) IC featuring a Clock/Calendar function. This component offers a 3-wire serial interface for communication and supports both 12/24 hour time formats and YY-MM-DD-dd date formats. Key features include leap year correction, integrated NVSRAM for data retention, a square wave output, and a trickle-charger input for backup battery management. The device operates within a voltage range of 1.2V to 5.5V for the main supply and 1.5V to 5.5V for battery backup. Timekeeping current consumption is typically between 25.3µA and 81µA, depending on the supply voltage. The PT7C4302ZEE is supplied in an 8-WFDFN exposed pad package suitable for surface mounting and is designed for operation across an industrial temperature range of -40°C to 85°C. This component is commonly utilized in applications within the industrial, consumer electronics, and automotive sectors.
