Dallas Precision Clock IC can replace time-based method of crystal

Dallas Semiconductor has introduced a precision timing applications for the replacement of quartz crystal oscillator designed for I2C Real Time Clock (RTC) - DS3231. The device integrates several functions, can be provided in a wide temperature range, better accuracy of ± 2 seconds per year.

DS3231 clock chip will be highly stable TCXO (TCXO), RTC, and CD4093BE datasheet and 32.768KHz crystals into a 16-pin 300 mil SOIC package, a single chip. It also includes a port can be accessed via I2C digital temperature sensor with an accuracy of ± 3 ℃.The integrated I2C

the RTC device for servers, ammeter, security and CD4093BE price and access control systems, logistics management, communications systems, GPS and CD4093BE suppliers and navigation equipment, POS terminals, ATMS or other needs accurate time of application. Compared with the traditional time, DS3231 at -40 ℃ to 85 ℃ operating temperature range, high precision 5-fold.

DS3231 RTC is available in commercial and industrial temperature versions, power supply voltage from 2.3V to 5.5V. 25,000-unit purchases, each $ 2.14 (for reference).
