com Rev 0; 2/06 Extremely Accurate SPI Bus RTC with Integrated Crystal and SRAM General Description The DS3234 is a low-cost, extremely accurate SPIā„¢ bus real-time clock (RTC) with an integrated temperaturecompensated crystal oscillator (TCXO) and crystal.
The DS3234 incorporates a precision, temperature-compensated voltage reference and comparator circuit to monitor VCC.
When VCC drops below the power-fail voltage (VPF), the device asserts the RST output and also disables read and write access to the part when VCC drops below both VPF and VBAT.
The RST pin is monitored as a pushbutton input for generating a reset externally.
The device switches to the backup supply input an...
