It is an opendrain terminal. Therefore, the SDA bus requires a pullupresistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for400 kHz).For normal data transfer SDA is allowed to change onlyduring SCL LOW. Changes during SCL HIGH arereserved for indicating the START and STOP conditions.8.2 Serial Clock (SCL)This input is used to synchronize the data transfer fromand to the device.8.3 Write-Protect (WP)This pin must be connected to either VSS or VCC.If tied to VSS normal memory operation is enabled(read/write the entire memory 000-7FF).If tied to VCC, WRITE operations are inhibited. Theentire memory will be write-protected. Read operationsare not affected.This feature allows the user to use the 24XX16 as aserial ROM when WP is enabled (tied to VCC).8.4 A0, A1, A2These pins are not used by the 24XX16. They may beleft floating or tied to either VSS or VCC.© 2002 Microchip Technology Inc. DS21703B-page 11
