FREI DS 3234 S - Real-time clock, clock/calendar, SO-20 FREI DS 3234 S - Real-time clock, clock/calendar, SO-20 26.44 EUR The DS3234 is a low-cost, extremely accurate SPI™ bus real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The DS3234 incorporates a precision, temperature-compen-sated voltage reference and comparator circuit to monitor V, CC. When V, CC drops below the power-fail voltage (V, PF), the device asserts the RST output and also disables read and write access to the part when V, CC drops below both V, PF and V, BAT. The RST pin is monitored as a pushbutton input for generating a µP reset. The device switches to the backup supply 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 DS3234 is available in commercial and industrial temperature ranges, and is offered in an industry-standard 300-mil, 20-pin SO package.
