DS3234 Real-time Clock Module for Arduino

DS3234 Real-time Clock Module for Arduino - Red

The module and Arduino are using the SPI modeÂ£Â¬ so the corresponding to SPI communication interface connectedÂ£Â¬ SCKÂ£Â¬ MISOÂ£Â¬ MOSIÂ£Â¬ CS and the module using 3.3V battery. Then take a good line burned into the routines codeÂ£Â¬ open the serial port observational dataÂ£Â¬ you will find the start timing and then power off and then on Arduino electricÂ£Â¬ and time is not resetÂ£Â¬ there is no lossÂ£Â¬ will continue and then timing. DS3234 also incorporates 256 bytes on battery backed up SRAM. When the main power failureÂ£Â¬ by connecting to the VBAT pin power supply are maintained on contents of the memory. The RTC can counting secondsÂ£Â¬ minutesÂ£Â¬ hoursÂ£Â¬ dayÂ£Â¬ dateÂ£Â¬ monthÂ£Â¬ and year information. For the less than 31 days of monthÂ£Â¬ can automatically adjust the date at the end of the month same time with a leap year correction. The clock operates in either 24 hours or 12 hours format with / AM / PM indication. For each day two programmable alarms and a programmable timing way output. SPI serial data transmission via bidirectional bus. - In the 0 ° C to + 40 ° C rangeÂ£Â¬ accuracy of ± 2ppm - In the -40 ° C to + 85 ° C rangeÂ£Â¬ accuracy of ± 3.5ppm - for provide battery backup uninterruptible timing input - Operating Temperature Range: Industrial: -40 ° C to + 85 ° C; commercial grade: 0 ° C to + 70 ° C - Provide two regular alarm clock every day - Programmable Output - 4MHz SPI interfaceÂ£Â¬ support for modes 1 and 3 -· Digital temperature sensor output: Accuracy of ± 3 ° C - With aging correction register - RST Input / Output
