Since it is an opendrainterminal, the SDA bus requires a pull-up resistorto VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz).For normal data transfer, SDA is allowed to changeonly during SCL low. Changes during SCL high arereserved for indicating Start and Stop conditions.8.2 Serial Clock (SCL)The SCL input is used to synchronize the data transferto 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 000-03FF).If tied to VCC, write operations are inhibited. The entirememory will be write-protected. Read operations arenot affected.This feature allows the user to use the 24XX08 as aserial ROM when WP is enabled (tied to VCC).8.4 A0, A1, A2The A0, A1 and A2 pins are not used by the 24XX08.They may be left floating or tied to either VSS or VCC.© 2005 Microchip Technology Inc.
