PIN DESCRIPTIONS
8.1
A0, A1, A2 Chip Address Inputs
The A0..A2 inputs are used by the 24FC65 for multiple
device operation and conform to the two-wire bus
standard. The levels applied to these pins define the
address block occupied by the device in the address
map. A particular device is selected by transmitting the
corresponding bits (A2, A1, A0) in the control byte
(Figure 3-2 and Figure 8-1).
8.2
SDA Serial Address/Data Input/Output
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 pullup
resistor to V
CC
(typical 1K
,
must consider total bus
capacitance and maximum rise/fall times).
For normal data transfer SDA is allowed to change only
during SCL low. Changes during SCL high are
reserved for indicating the START and STOPs.
8.3
SCL Serial Clock
This input is used to synchronize the data transfer from
and to the device.
