产品概述
DS3234S# 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-compensated voltage reference and comparator circuit to monitor VCC. When VCC drops below the power-fail voltage (VPF), the device asserts the active-low RST output and also disables read and write access to the part when VCC drops below both VPF and VBAT. The active-low 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 the 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. Applications include servers, utility power meters, telematics, and GPS.
- Highly accurate RTC with integrated crystal and SRAM completely manages all timekeeping functions
- Frequency stability vs temperature is +2ppm at 0°C to +40°C, VCC=3.3V or VBAT=3.3V
- Digital temp sensor output: ±3°C accuracy
- Register for aging Trim, RST input/output
- Two time-of-day alarms, programmable square-wave output
- Simple serial interface connects to most microcontrollers, 4MHz SPI bus supports modes 1 and 3
- Battery-backup input for continuous timekeeping, low power operation extends battery backup run time
- Underwriters Laboratories® (UL) recognized
- 20 SO package
- 0°C to +70°C temperature rating
