Realtime clock package eliminates need for a separate crystal

17 November 2004 DSP, Micros & Memory

Dallas Semiconductor has released four serial realtime clocks that include a 32,768 kHz crystal in a 16-pin SO package. Combining the crystal in the package eliminates potential sourcing, layout, and manufacturing issues that arise when matching the crystal to the realtime clock, resulting in a simpler implementation for the user.

The DS1337C/DS1338C/DS1339C/DS1374C devices offer a number of features, including automatic power switching, trickle-charge output, alarms, binary-coded decimal time or binary counter, and 1,8 V to 5 V operating voltages.

The new package variants are rated for operation over the industrial temperature range (-40 to +85°C).
