Product Summary

The DS3232 is a low-cost temperature-compensated
crystal oscillator (TCXO) with a very accurate, temperature-
compensated, integrated real-time clock (RTC) and
236 bytes of battery-backed SRAM. Additionally, the
DS3232 incorporates a battery input and maintains accurate
timekeeping when main power to the device is interrupted.
The integration of the crystal resonator enhances
the long-term accuracy of the device as well as reduces
the piece-part count in a manufacturing line. The DS3232
is available in commercial and industrial temperature
ranges, and is offered in an industry-standard 20-pin,
300-mil SO package.
