PT7C4302WE

IC RTC CLK/CALENDAR SER 8SOIC

Manufacturer: Diodes Incorporated

Categories: Real Time Clocks

Quality Control: Learn More

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.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
