DS3234 Datasheet Extremely ACcurate Spi Bus Rtc

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: www.DataSheet4U.com Rev 0; 2/06 Extremely Accurate SPI Bus RTC with Integrated Crystal and.

General Description

The DS3234 is a low-cost, extremely accurate SPI™ 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.

Key Features

  • Accuracy ±2ppm from 0°C to +40°C.
  • Accuracy ±3.5ppm from -40°C to +85°C.
  • Battery Backup Input for Continuous Timekeeping.
  • Operating Temperature Ranges Commercial: 0°C to +70°C Industrial: -40°C to +85°C.
  • Low-Power Consumption.
  • Real-Time Clock Counts Seconds, Minutes, Hours, Day, Date, Month, and Year with Leap Year Compensation Valid Up to 2099.
  • Two Time-of-Day Alarms.
  • Programmable Square-Wave Output.
  • 4MHz SPI Bus S.
