24LLC02 Pin Descriptions

Name

Type

Description

Circuit

Type

A0, A1, A2

Input

Input pins for device address selection. To configure a device address,

these pins should be connected to the VCC or VSS of the device.

These pins are internally pulled down to VSS .

V SS

–

Ground pin.

–

SDA

I/O

Bi-directional data pin for the I

2C-bus serial data interface. Schmitt

trigger input and open-drain output. An external pull-up resistor must

be connected to VCC. Typical values for this pull-up resistor are 4.7 k Ω

(100 kHz) and 1 k

Ω (400 kHz).

SCL

Input

Schmitt trigger input pin for serial clock input.

Input

Input pin for hardware write protection control. If you tie this pin to VCC,

the write function is disabled to protect previously written data in the

entire memory; if you tie it to VSS , the write function is enabled.

This pin is internally pulled down to VSS .

V CC

–

Single power supply.
