SCL
This input clock pin is used to synchronize the data
transfer to and from the device.
SDA
The SDA is a Bi-directional pin used to transfer addresses
and data into and out of the device. The SDA pin is an open
PIN CONFIGURATION
8-Pin DIP and SOIC
drain output and can be wire Or'ed with other open drain
or open collector outputs. The SDA bus
requires
a pullup
resistor to Vcc.
A0, A1, A2
The A0, A1, and A2 are the device address inputs that are
hardwired or left not connected for hardware compatibility
with the IS24C32/64/128. When pins are hardwired, as
many as eight 256K devices may be addressed on a single
bus system. When the pins are not hardwired, the default
A0, A1, and A2 are zero.
WP
WP is the Write Protect pin. If the WP pin is tied to Vcc
the entire array becomes Write Protected (Read only).
When WP is tied to GND or left floating, normal read/write
operations are allowed to the device.
