The Analog Devices Inc./Maxim Integrated DS1501W is a Real Time Clock (RTC) IC offering 256 bytes of NVSRAM for timekeeping and data storage. This Clock/Calendar component features a parallel interface and is housed in a 28-DIP (0.600", 15.24mm) package suitable for through-hole mounting. Key features include alarm functionality, leap year compensation, a watchdog timer, and square wave output. The DS1501W operates with a supply voltage range of 3V to 3.6V, with battery backup support from 2.5V to 3.7V. Timekeeping current consumption is a maximum of 4mA at 3V. Supported date formats include YY-MM-DD-dd, and time is presented in HH:MM:SS (24 hr) format. This component finds application in industrial automation, medical devices, and consumer electronics where accurate timekeeping and data retention are critical.
