Iasi Iasi Telefon validat azi Atentie, am foarte multe produse, module, shield-uri, pentru proiecte, licente, decat cele afisate, va rog sa-mi solicitati lista completa DS3231 AT24C32 IIC Precision RTC Real Time Clock Memory Module For Arduino Are 32 k memorie eeprom Are baterie de bekkup Are 2 alarme Are ajustare fina la ceas (hard si soft) posibilitate de ajustare a avansului ceas. Trebuie baterie CR2032 la 3 volti real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping. Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line. DS3231 available in commercial and industrial temperature ranges, using a 16-pin 300mil SO package. RTC maintains seconds, minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. Clock operates in either the 24 hours or band AM PM indication of the 12-hour format. 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. A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output, and if necessary, automatically switch to the backup power supply. /RST pin is monitored as generating µP reset manually. Save time and high precision addition, DS3231 also has some other features that extend the system host of additional features and a range of options. The device integrates a very precise digital temperature sensor, through the I2C * interface to access it (as the same time). Temperature sensor accuracy is ± 3 ° C. On-chip power supply control circuit can automatically detect and manage the main and standby power (i.e., low-voltage battery) to switch between the power supply. If the main power failure, the device can continue to provide accurate timing and temperature, performance is not affected. When the main power re-power or voltage value returns to within the allowable range, the on-chip reset function can be used to restart the system microprocessor Module parameters: Size: 38mm (length) * 22mm (W) * 14mm (height) Operating voltage :3.3 - 5 .5 V clock chip: high-precision clock chip DS3231 Clock Accuracy :0-40 centigrade range, the accuracy 2ppm, the error was about 1 minute Calendar alarm clock with two Programmable square-wave output Real time clock generator seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensation Chip temperature sensor comes with an accuracy of ± 3 centigrade transmission speed of 400KHz SCL › A5 SDA › A4 VCC › 5V ... 3,3 V GND › GND Produs nou sigilat.
