Detailed Pin Configuration

The CAT24C04WI-G has the following pin configuration:

1. A0: Address input bit 0
2. A1: Address input bit 1
3. A2: Address input bit 2
4. GND: Ground
5. SDA: Serial data input/output
6. SCL: Serial clock input
7. WP: Write protect
8. VCC: Power supply

Functional Features

• Random access: Allows reading and writing of data at any memory location.
• Byte-level operations: Supports individual byte read, write, and erase operations.
• Sequential read: Enables consecutive reading of multiple memory locations.
• Hardware write protection: The WP pin can be used to protect the memory from accidental writes.

Advantages and Disadvantages

Advantages

• Non-volatile storage: Data remains intact even during power loss.
• High endurance: Can withstand a large number of write/erase cycles.
• Low power consumption: Operates efficiently with low power requirements.
• Compact package: Comes in a small form factor, suitable for space-constrained designs.

Disadvantages

• Limited storage capacity: With only 4 kilobits, it may not be sufficient for certain applications requiring larger memory sizes.
• Relatively slower write speed compared to other memory technologies.

Working Principles

The CAT24C04WI-G utilizes electrically controlled floating gate transistors to store and retrieve digital information. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during the erase operation, allowing new data to be written.
