well, take a look what offers each device, for example
DS1307: can support a battery can use ds32khz and make it very precise has code example PCF8583: built in 32KHz oscilator more resolution you can consider price, power, if you use a battery for backup, etc so the better you describe your application we can decide which is the most appropiate device for the specific application the 2 IC support a maximum i2c bus of 100KHz http://www.semiconductors.philips.com/pip/PCF85...F8583.html http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2688 |
