FUNCTIONAL DESCRIPTION
The CAT24WC66 supports the I2C Bus data transmission
protocol. This Inter-Integrated Circuit Bus protocol defines
any device that sends data to the bus to be a transmitter
and any device receiving data to be a receiver. The
transfer is controlled by the Master device which
generates the serial clock and all START and STOP
conditions for bus access. The CAT24WC66 operates
as a Slave device. Both the Master device and Slave
device can operate as either transmitter or receiver, but
the Master device controls which mode is activated.
PIN DESCRIPTIONS
SCL: Serial Clock
The serial clock input clocks all data transferred into or
out of the device.
SDA: Serial Data/Address
The bidirectional serial data/address pin is used to
transfer all data into and out of the device. The SDA pin
is an open drain output and can be wire-ORed with other
open drain or open collector outputs.
A0, A1, A2: Device Address Inputs
These pins are hardwired or left unconnected (for
hardware compatibility with CAT24WC16).
When
hardwired, up to eight CAT24WC66 devices may be
addressed on a single bus system (refer to Device
Addressing ). When the pins are left unconnected, the
default values are zeros.
WP: Write Protect
This input, when tied to GND, allows write operations to
the entire memory. When this pin is tied to Vcc, the top
1/4 array of memory is write protected.
When left
floating, memory is unprotected.
