HW-084A DS3231 AT24C32 Precision Clock Module 3.3-5.5V IIC RTC Real Time Clock Memory Module NO Battery Feature: DS3231 is a low-cost, high-precision I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device includes a battery input terminal, which can maintain accurate timing when the main power supply is disconnected. The integrated crystal oscillator improves the long-term accuracy of the device and reduces the number of components in the production line. DS3231 offers commercial grade and industrial grade temperature range, adopts 16-pin 300mil SO package. RTC saves seconds, minutes, hours, day of the week, date, month and year information. For months with less than 31 days, the date at the end of the month will be automatically adjusted, including corrections for leap years. And provide leap year compensation valid until 2100. The working format of the clock can be 24-hour or 12-hour format with AM/PM indication. Provides two configurable calendar alarms and a configurable square wave output. Address and data are serially transmitted via I2C bidirectional bus. IIC bus interface, transmission speed 400KHz (when working voltage is 5V). Other IIC devices can be cascaded. The 24C32 address can be modified by short-circuiting A0/A1/A2. The default address is 0x57. A precise, temperature-compensated voltage reference and comparator circuit is used to monitor the VCC status, detect power failures, provide a reset output, and automatically switch to a backup power supply when necessary. In addition, the RST monitor pin can be used as a manual input to generate a μP reset. In addition to high timing accuracy, DS3231 also has some other functions, which expand the additional functions and selection range of the system host. The device integrates a very accurate digital temperature sensor, which can be accessed through the I2C* interface (as time). The accuracy of this temperature sensor is ±3°C. The on-chip control circuit can realize automatic power detection and manage the power switch between the main power supply and the backup power supply (ie, low-voltage battery). If the main power supply fails, the device can continue to provide accurate timing and temperature, and its performance will not be affected. When the main power supply is re-energized or the voltage value returns to the allowable range, the on-chip reset function can be used to restart the system microprocessor. Specification: Working voltage: 3.3-5.5V Clock chip: High-precision clock chip DS3231 Clock accuracy: Within the range of 0-40℃, accuracy is 2ppm, and the annual error is about 1 minute Memory chip: AT24C32 (storage capacity 32K) Product size: 38*22*14mm Product weight: 9g Packing size: 50*50*20mm Package weight: 9g Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement.Included:1 X DS3231 Module
