Low-power RTC with binary counter cuts component count

Maxim Integrated Products has unveiled the DS1372 real-time clock (RTC) with a binary counter and unique 64bit serial number for digital data applications.

The DS1372's integration of a binary counter and unique 64-bit serial number not only satisfies digital rights management requirements, but also enables designers to reduce system component count and use a less expensive processor. Offering both of these features in an 8-pin microSOP package, the RTC is designed for use in MP3/MP4/PMP players, personal, digital cameras, and point-of-sale terminals.

In addition, the DS1372's binary counter allows easy conversion to time-of-day and elapsed-time measurements. The 64-bit serial number is factory-lasered into the device to eliminate the need for costly user programming and to prevent tampering with the serial number. Designed for battery-backed applications in which low current consumption is critical, the DS1372 consumes 450nA at 3V. The use of this low-power RTC in a typical battery-backed MP3 player enables the application to shut down the main processor to conserve battery life.

The DS1372 is available in an RoHS-compliant, 8-pin microSOP package that is fully specified over the -40C to 85C operating temperature range. Prices start at 93 cents (1000-up, FOB USA).
