- DS3231 16-pin memory chips - AT24C32 ,extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
- Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line.
- Provides two configurable alarm clock and a calendar can be set to a square wave output. Address and data are transferred serially through an I2C bidirectional bus.
- Highly accurate RTC completely manages all timekeeping functions.The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping.
- A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output. In addition, RST pin is monitored as generating a μP reset.
