Description

The device DS3234 RTC Breakout by Soldered is a precision real-time clock module based on the DS3234 IC with an integrated temperature-compensated crystal oscillator TCXO. It provides timekeeping accuracy of ±2ppm from 0 to +40°C and ±3.5ppm from -40 to +85°C. The device keeps track of seconds, minutes, hours, day, date, month and year and automatically handles leap years through 2099.

Communication with the host microcontroller is provided through a 4-wire SPI interface operating in mode 1 or 3. The DS3234 provides two programmable alarms, a programmable square-wave output and a 32.768kHz clock output. The IC also includes 256B of battery-backed SRAM and a digital temperature sensor used for oscillator compensation.

The module operates from a supply voltage of 2.0V to 5.5V and includes a holder for a CR2032 battery, allowing the clock to retain time when the main power supply is disconnected. The battery is not included. The main signals of the DS3234 are exposed on the board, and the design is compatible with breadboards. The project is open-source.
