The Analog Devices Inc./Maxim Integrated DS1553-70 is a Real Time Clock (RTC) module featuring an 8KB parallel NVSRAM. This clock/calendar IC provides critical timekeeping functions, including alarm, leap year compensation, and a watchdog timer, with support for Y2K. It operates with a supply voltage range of 4.5V to 5.5V and draws a maximum of 3mA at 5V. The DS1553-70 utilizes a parallel interface for data access and offers both HH:MM:SS (24-hour) and YY-MM-DD-dd date formats. Packaged in a 28-EDIP through-hole mount, this component is suitable for applications requiring robust timekeeping and non-volatile data storage, commonly found in industrial control, data logging, and embedded systems. The operating temperature range is 0°C to 70°C.
