EPSON RTC-4543SA-A0 is a 3-wire serial clock/calendar IC designed for precise timekeeping. This component offers a 24-hour time format (HH:MM:SS) and supports a YY-MM-DD-dd date format, including leap year functionality. Operating within a voltage range of 2.5V to 5.5V, it exhibits low current consumption for timekeeping, typically between 1µA and 3µA. The device is housed in a 14-SOIC (0.197", 5.00mm Width) surface-mount package, supplied on tape and reel. Its robust operating temperature range of -40°C to 85°C makes it suitable for applications in industrial control, consumer electronics, and automotive systems where reliable timekeeping is critical.
