DS3232 Datasheet Extremely ACcurate I2c Rtc

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: AVAILABLE EVALUATION KIT AVAILABLE DS3232 Extremely Accurate I2C RTC with Integrated Crystal and SRAM.

General Description

The DS3232 is a low-cost temperature-compensated crystal oscillator (TCXO) with a very accurate, temperature-compensated, integrated real-time clock (RTC) and 236 bytes of battery-backed SRAM.

Additionally, the DS3232 incorporates a battery 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.

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.
  • 236 Bytes of Battery-Backed SRAM.
  • 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.
