Overview
The DS3231MZEVKIT# is an evaluation kit designed for the DS3231M real-time clock (RTC) module, produced by Analog Devices Inc./Maxim Integrated. This kit is a fully assembled and tested circuit board that demonstrates the operation of the DS3231M temperature-compensated RTC. The DS3231M incorporates an internal silicon (MEMS) resonator and a temperature-compensated crystal oscillator (TCXO), ensuring highly accurate timekeeping by periodically adjusting the internal oscillator frequency based on operating temperature.
The evaluation kit includes a USB I/O communications module (DS3900H2), a CD with the application program and instructions, and supports various power-supply configurations such as dual supply, single supply using VCC, and single supply using VBAT. It is compatible with Windows XP, Vista, or later versions and requires a USB port for operation.
