2.0
The descriptions of the pins are listed in Table 2-1.
TABLE 2-1:
2.1
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.
2.2
This input is used to synchronize the data transfer from
and to the device.
2.3
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 24C01C devices may be connected to the
same bus by using different Chip Select bit combina-
tions. These inputs must be connected to either V
V
2.4
This pin is utilized for testing purposes only. It may be
tied high, tied low or left floating.
2.5
The 24C01C employs a V
which disables the internal erase/write logic if the V
is below 3.8 volts at nominal conditions.
The SCL and SDA inputs have Schmitt Trigger and
filter circuits which suppress noise spikes to assure
proper device operation even on a noisy bus.
