EEPROM Operation Timing

Before operating EERPOM, you must first learn the IIC protocol

 

1. Single byte - write operation

 

Timing: start signal + 8-bit device address + high 8-bit address + low 8-bit address + data + stop signal

Note: When EEPROM writes data, it takes 5ms to address. During this time, the EEPROM does not respond to any operation from the outside world, as if it disappeared from the IIC bus. Therefore, when encoding, read and write must add delay5ms ( );
