TABLE 2-1: PIN FUNCTION TABLE 2.1 SDA Serial Data This is a bidirectional pin used to transfer addresses and data into and data out of the device. It is an open drain terminal; therefore, the SDA bus requires a pull- up resistor to VCC (typical 10 k Ω for 100 kHz, 2 kΩ for 400 kHz). For normal data transfer SDA is allowed to change only during SCL low. Changes during SCL high are reserved for indicating the Start and Stop conditions. 2.2 SCL Serial Clock This input is used to synchronize the data transfer from and to the device. 2.3 A0, A1, A2 The levels on these inputs are compared with the corresponding bits in the slave address. The chip is selected if the compare is true. Up to eight 24C02C devices may be connected to the same bus by using different Chip Select bit combina- tions. These inputs must be connected to either VCC or VSS. 2.4 WP This is the hardware write-protect pin. It must be tied to VCC or VSS. If tied to Vcc, the hardware write protection is enabled. If the WP pin is tied to VSS the hardware write protection is disabled. 2.5 Noise Protection The 24C02C employs a VCC threshold detector circuit which disables the internal erase/write logic if the VCC is below 3.8 volts at nominal conditions. The SCL and SDA inputs have Schmitt Trigger and filter circuits which suppress noise spikes to assure proper device operation even on a noisy bus.
