Pinout
This EEPROM comes in an 8-pin Small Outline Integrated Circuit (SOIC) package. Here is a brief description of its pin functions:
1. A0, A1, A2 (Pins 1-3): These pins are used for device addressing, allowing up to eight devices on the same bus.
2. VSS (Pin 4): Ground pin.
3. SDA (Pin 5): Serial Data line, used for data input and output.
4. SCL (Pin 6): Serial Clock line, used to synchronize data transfer.
5. WP (Pin 7): Write Protect pin, which can be used to disable write operations for added data protection.
6. VCC (Pin 8): Supply voltage pin, typically ranging from 2.5V to 5.5V.
The 24LC64T-I/ST is designed for applications requiring non-volatile storage with a simple interface, such as data logging, settings retention, and similar uses in embedded systems.
