The descriptions of the pins are listed in Table 8-1.
TABLE 8-1:
8.1
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 24XX52 devices may be connected to the
same bus by using different Chip Select bit
combinations. These inputs must be connected to
either V
8.2
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 V
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.
