DS3231SN#T&RReal-TimeClock IC High Accuracy Timekeeping chip
The DS3231SN#T&R is an extremely accurate real-time clock (RTC) IC from Analog Devices, featuring a temperature-compensated crystal oscillator (TCXO) and crystal. It is designed to provide highly reliable timekeeping across a wide range of applications, including industrial, automotive, and consumer electronics. This device offers a high degree of accuracy, with an error of only ±2 ppm (parts per million) over the operating temperature range of -40°C to +85°C. It also includes a battery input for maintaining accurate timekeeping when the main power supply is interrupted.
The DS3231SN#T&R features a serial I2C interface, allowing for easy communication with microcontrollers and other devices. It supports a fast-mode I2C interface with a clock frequency of up to 400kHz. The chip includes multiple functionalities such as two programmable time-of-day alarms, a programmable square-wave output signal, and a digital temperature sensor output. Additionally, it provides automatic leap-year compensation until the year 2100.
The DS3231SN#T&R is packaged in a 16-pin SOIC (Small Outline Integrated Circuit) with a 300-mil width, suitable for surface-mount applications. It operates on a supply voltage range of 2.3V to 5.5V. The device is designed for low power consumption, making it ideal for battery-powered systems where power efficiency is critical. It also features a backup switching mechanism to ensure continuous operation during power transitions.
