Keywords:real-time clocks? I2C? power supply?

This application note by Maxim Integrated presents an overview of the operational characteristics of accurate I2C real-time clocks (RTCs), including the DS3231, DS3231M, and DS3232. It focuses on general application guidelines that facilitate use of device resources for power management, I2C communication circuit configurations, and I2C characteristics relative to device power-up sequences and initialisations. Additional discussions on decoupling are provided to support developing strategies for mitigating power supply pushing of device frequency.
