Dallas Semiconductor has unveiled four serial real-time clocks (RTCs) that include a 32.768kHz 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 real-time clock, the company said, resulting in a simpler implementation for the user.

The new DS1337C, DS1338C, DS1339C and DS1374C devices feature automatic power switching, trickle-charge output, alarms, binary-coded decimal time or binary counter, and 1.8V to 5V operating voltages.

The new package variants are rated for operation over the industrial temperature range. Prices start at $1.23 for the DS1337C, $1.52 for the DS1338C and DS1339C, and $1.65 for the DS1374C (1,000-up, FOB USA).
