DS3234 Description
The DS3234 is a low-cost, extremely accurate SPI™ bus real-time clock (RTC) with an integrated temperaturepensated crystal oscillator (TCXO) and crystal. The DS3234 incorporates a precision, temperature-pensated voltage reference and parator 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...
