As can be seen in the diagram on this slide, the circuitry required to connect an EEPROM to an embedded system is fairly basic. To prevent faulty writes and data corruption during power-up and power-down, a pull-up resistor is placed on the write protection (WP) pin. Additional pull-up resistors can be placed on the communications bus lines to optimize circuit design and power consumption. Finally, a decoupling capacitor is placed between Vcc and GND to suppress high frequency noise from the power supply.
