The Analog Devices Inc./Maxim Integrated DS1501WE is a Real Time Clock (RTC) IC offering parallel interface access to its clock and calendar functions. This component features 256 bytes of non-volatile RAM for data storage, accessible via the parallel interface. Key functionalities include alarm generation, leap year compensation, and a watchdog timer for system monitoring. The DS1501WE also provides a square wave output and supports Y2K compliance. It operates from a supply voltage range of 3V to 3.6V, with a battery backup input range of 2.5V to 3.7V, drawing a maximum of 4mA during timekeeping. The device is supplied in a 28-TSSOP package with a 28-TSOP supplier device package, suitable for surface mounting. Supported date and time formats are YY-MM-DD-dd and HH:MM:SS (24 hr) respectively. This RTC is commonly found in industrial automation, consumer electronics, and data logging applications.
