8-Pin SOIC, TSSOP
PIn DESCRIPTIOnS
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 drain output and can be wire Or'ed with other open
drain or open collector outputs. The SDA bus 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 IS24C32A/64A. When pins are hardwired, as many
as eight 128K devices may be addressed on a single bus
system. When the pins are not hardwired, the default values
of 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.
