Hi
we are using EEPRM AT24C512 in our LPC812 micro controller Based data logger project. The I2C communication is working properly (continuously) for 2 or 3 days with out any problem. But suddently it is giving all data as "00" (mostly). The connection we have made with AT24C512 is given in diagram. please suggest for a solution EEPROM.png
Thanks
