Patent ID: 7417892

Claim:
An electrical device for accessing an I2C EEPROM comprising: a controller; a power supply terminal of the I2C EEPROM; a power supply unit electrically connected to the controller and the I2C EEPROM; a clock line electrically connecting the controller to the I2C EEPROM; a data line that electrically connects the controller to the I2C EEPROM; a first resistor connected to the data line and arranged on to the electrical connection between the power supply unit and the I2C EEPROM; a second resistor connected to the clock line and arranged on to the electrical connection between the power supply unit and the I2C EEPROM; a first externally accessible terminal connected to the clock line in parallel; a second externally accessible terminal connected to the data line in parallel; a decoupling diode arranged between the electrical connection of the power supply unit and the first and second resistor; and a capacitor electrically connected to the power supply terminal of the I2C EEPROM.
