AT24C02A-10TI-2.7-T

Product Overview

Category

AT24C02A-10TI-2.7-T belongs to the category of electrically erasable programmable read-only memory (EEPROM) chips.

Use

This product is commonly used for storing and retrieving data in electronic devices.

Characteristics

• Electrically erasable: The stored data can be erased and rewritten electronically, without requiring a physical intervention.
• Programmable: The chip can be programmed to store specific data.
• Read-only memory: The stored data can only be read and not modified by the user.

Package

AT24C02A-10TI-2.7-T is available in a small surface mount package.

Essence

The essence of this product lies in its ability to provide non-volatile storage for electronic devices, allowing them to retain data even when power is removed.

Packaging/Quantity

AT24C02A-10TI-2.7-T is typically packaged in reels or tubes, with a quantity of 2500 units per reel/tube.

Specifications

• Memory Size: 2 kilobits (256 bytes)
• Operating Voltage: 2.7V to 5.5V
• Speed: 400 kHz (Fast Mode)
• Write Cycle Time: 5 ms (maximum)
• Data Retention: 100 years (minimum)

Detailed Pin Configuration

The AT24C02A-10TI-2.7-T chip has a total of 8 pins, each serving a specific purpose:

1. A0: Address Input
2. A1: Address Input
3. A2: Address Input
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 for reading and writing data at any memory location.
• Sequential Read: Supports sequential reading of multiple memory locations.
• Write Protection: The WP pin can be used to protect the stored data from being overwritten.
• Hardware Write Control: Ensures that data is written only when the voltage supply is within the specified range.

Advantages and Disadvantages

Advantages

• Non-volatile storage: Data remains intact even when power is lost.
• Small form factor: Compact size makes it suitable for space-constrained applications.
• High-speed operation: Supports fast data transfer rates.

Disadvantages

• Limited storage capacity: With a memory size of 2 kilobits, it may not be sufficient for certain applications requiring larger data storage.
• Limited write endurance: The chip has a maximum write cycle time, which may limit its lifespan in applications with frequent data updates.

Working Principles

AT24C02A-10TI-2.7-T utilizes electrically controlled floating gate transistors to store and retrieve data. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during the erasing process, allowing new data to be written.

Detailed Application Field Plans

AT24C02A-10TI-2.7-T finds application in various electronic devices, including but not limited to: - Consumer electronics (e.g., TVs, set-top boxes) - Automotive systems (e.g., infotainment systems, engine control units) - Industrial automation (e.g., programmable logic controllers, sensors) - Medical devices (e.g., patient monitoring systems, diagnostic equipment)
