TABLE 8-1: PIN FUNCTION TABLE 8.1 Serial Address/Data Input/Output (SDA) SDA is a bidirectional pin used to transfer addresses and data into and out of the device. Since it is an open- drain terminal, 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 Start and Stop conditions. 8.2 Serial Clock (SCL) The SCL input is used to synchronize the data transfer to and from the device. 8.3 Write-Protect (WP) The WP pin must be connected to either VSS or VCC. If tied to VSS, normal memory operation is enabled (read/write the entire memory 00-FF). If tied to VCC, write operations are inhibited. The entire memory will be write-protected. Read operations are not affected. This feature allows the user to use the 24XX02 as a serial ROM when WP is enabled (tied to VCC). 8.4 A0, A1, A2 These A0, A1 and A2 pins are not used by the 24XX02. They may be left floating or tied to either VSS or VCC.
