Product details

RTC with integrated NVSRAM and watchdog

The DS1554-70+ is a full-function real-time clock (RTC) with a parallel interface, integrating 32KB of non-volatile SRAM, a watchdog timer, alarm, leap-year compensation, and Y2K compliance in a single 32-pin EDIP module.

The through-hole 32-EDIP package (0.600-inch body width) provides a robust mechanical interface for socketed or soldered board integration, common in legacy industrial and test-equipment designs.
