Analog Devices Inc./Maxim Integrated DS1557P-70 is a Real Time Clock (RTC) Clock/Calendar module featuring a 512KB parallel interface. This component includes an integrated NVSRAM, providing non-volatile storage capabilities essential for critical data retention. The DS1557P-70 offers advanced features such as an alarm function, leap year compensation, and a watchdog timer, enhancing system reliability and operational precision. Its 34-PowerCap™ Module package is designed for surface mounting. Operating within a voltage range of 4.5V to 5.5V, with a battery voltage support of 3V, it is suitable for applications requiring robust timekeeping and data integrity. Typical applications include industrial control systems, networking equipment, and point-of-sale terminals where accurate timekeeping and data logging are paramount. The device operates at a maximum current of 6mA at 5V and supports both HH:MM:SS (24 hr) time and YY-MM-DD-dd date formats.
