Specification Brand : Beaster BulletPoint : KR1816VE51 analoge 8051 IC / Microchip USSR 2 pcs BulletPoint1 : DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. BulletPoint2 : Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line. BulletPoint3 : 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. BulletPoint4 : 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. BulletPoint5 : 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. In addition, RST pin is monitored as generating ?P reset manually.
