The Diodes Incorporated PT7C4302WE is a highly integrated Real Time Clock (RTC) IC designed for accurate timekeeping. This clock/calendar component features a 3-wire serial interface for efficient data communication and a 31-byte NVSRAM for storing configuration and timekeeping data. Its operational voltage range is 1.2V to 5.5V, with a battery voltage input also supporting 1.5V to 5.5V. The device offers a timekeeping current draw of 25.3µA to 81µA, making it suitable for low-power applications. Key features include leap year compensation, a square wave output, and a trickle-charger for maintaining battery backup. The PT7C4302WE is housed in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, operating across a temperature range of -40°C to 85°C. This component finds application in automotive, industrial, and consumer electronics sectors requiring reliable timekeeping.
