Product Features
- DS3231: DS3231 is a cost-effective, extremely accurate I2C real-time clock (RTC) with integrated temperature-compensated quartz oscillator (TCXO) and quartz. The device has a battery input, disconnects the main power supply and ensures accurate time keeping. The integrated oscillator improves the long-term accuracy of the device and reduces the number of components of the production line. The DS3231 is available in commercial and industrial temperature ranges and features
- Compact design Size: 38 mm (length) x 22 mm (W) x 14 mm (height); Weight: 8 g; Operating voltage: 3.3 - 5.5 V; clock chip: high-accuracy clock chip DS3231; clock accuracy: range 0-40, accuracy 2ppm, error approx. 1 minute;
- Compatibility: calendar alarm clock with two; programmable rectangular output; real-time clock generator seconds, minutes, hours, day, date, month and year, valid up to the year 2100 as a leap year; the chip temperature sensor has an accuracy of 3; memory modules: AT24C32 (storage capacity 32K);
- High performance: IIC bus interface, maximum transmission speed of 400 kHz (working voltage of 5 V); can be cascaded with other IIC devices, 24C32 addresses can be short-circuited. A0 / A1 / A2 standard address change is 0 x 57; with the rechargeable battery CR2032, the device can normalise natural movement after a power failure. Packaging: single anti-static packaging
