MAX31343 - I2C Real-Time Clock

General Description

The MAX31343 is a low-cost, extremely accurate, I2C real-time clock (RTC).

The device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted.

Key Features

  • including two programmable time-ofday alarms, interrupt output, uncompensated programmable clock output, and temperature-compensated programmable square-wave output. Address and data are transferred serially through an I2C bidirectional bus. A voltage reference and comparator circuit monitors the status of VCC to detect power failures and automatically switch to the backup supply when necessary. See the Typical.

EVALUATION KIT AVAILABLE MAX31343 Click here to ask an associate for production status of specific part numbers. ±5ppm, I2C Real-Time Clock with Integrated MEMS Oscillator General Description The MAX31343 is a low-cost, extremely accurate, I2C real-time clock (RTC). The device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. The integration of the microelectromechanical systems (MEMS) resonator enhances the long-term accuracy of the device and eliminates the external crystal requirement in the system. The MAX31343 is available in the 8-pin WLP and TDFN packages. The RTC maintains seconds, minutes, hours, day, date, month, year, and century information.
