Write-Protect (WP)
(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 V CC (typical 10 k Ω for 100 kHz, 2 k Ω 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.
The WP pin must be connected to either V SS or V CC .
If tied to V SS , normal memory operation is enabled
(read/write the entire memory 000-1FF).
If tied to V CC , write operations are inhibited. The entire
memory will be write-protected. Read operations are
not affected.
The Chip Scale package does not support the write-
protect feature.
2.2
Serial Clock (SCL)
2.4
A0, A1, A2
The SCL input is used to synchronize the data transfer
to and from the device.
? 2009 Microchip Technology Inc.
The A0, A1 and A2 pins are not used by the 24XX04.
They may be left floating or tied to either V SS or V CC .
