Feature Comparison of the DS323x Real-Time Clocks

By: Hrishikesh Shinde

Abstract: This application note explains the differences between several Maxim real-time clocks (RTCs), including the DS3231, DS3232, DS3234, DS32B35, and DS32C35, to help customers identify the proper solution for their application. The DS3231M, which has a built-in microelectronic mechanical systems (MEMS) resonator instead of a crystal, is also discussed.
