PIN CONFIGURATION

PIN DESCRIPTIONS

Serial Clock (SCL)

The SCL input is used to clock all data into and out of the

device.

Serial Data (SDA)

SDA is a bidirectional pin used to transfer data into and out

of the device. It is an open drain output and may be

wire-ORed with any number of open drain or open

collector outputs.

An open drain output requires the use of a pull-up

resistor. For selecting typical values, refer to the Guide-

lines for Calculating Typical Values of Bus Pull-Up

Resistors graph.

Address (A0, A1, A2)

The address inputs are used to set the least significant

three bits of the seven bit slave address. These inputs

can be static or actively driven. If used statically they must

be tied to VSS or VCC as appropriate. If actively

driven, they must be driven to VSS or to VCC.

Write Control (WC)

The Write Control input controls the ability to write to the

device. When WC is LOW (tied to VSS) the X24C02 will

be enabled to perform write operations. When WC is HIGH

(tied to VCC) the internal high voltage circuitry will

be disabled and all writes will be disabled.
