24AA01H-I/S16K

Product Overview

Category

The 24AA01H-I/S16K belongs to the category of electrically erasable programmable read-only memory (EEPROM) chips.

Use

This product is commonly used in electronic devices for non-volatile data storage. It allows for easy reading and writing of data even when power is removed.

Characteristics

• Non-volatile: Retains data even without power supply.
• Electrically erasable: Allows for easy modification of stored data.
• Programmable: Data can be written and rewritten multiple times.
• Read-only memory: Data can be read but not modified by external devices.

Package

The 24AA01H-I/S16K is available in a small surface mount package, making it suitable for compact electronic devices.

Essence

The essence of this product lies in its ability to store and retrieve data reliably, even in the absence of power. This makes it an essential component in various electronic applications.

Packaging/Quantity

The 24AA01H-I/S16K is typically packaged in reels or tubes, with each reel or tube containing a specific quantity of chips. The exact packaging and quantity may vary depending on the manufacturer.

Specifications

• Memory Size: 1 kilobit (128 bytes)
• Interface: I2C (Inter-Integrated Circuit)
• Operating Voltage: 1.7V to 5.5V
• Operating Temperature Range: -40°C to +85°C
• Write Endurance: 1 million write cycles
• Data Retention: 200 years

Detailed Pin Configuration

The 24AA01H-I/S16K has a total of 8 pins, each serving a specific purpose:

1. VCC: Power supply input
2. SDA: Serial data line for communication
3. SCL: Serial clock line for synchronization
4. WP: Write protect pin to enable/disable write operations
5. A0: Address bit 0 for device addressing
6. A1: Address bit 1 for device addressing
7. GND: Ground connection
8. NC: No connection (unused pin)

Functional Features

• Byte-level Read/Write: Allows individual bytes of data to be read from or written to the memory.
• Sequential Read: Supports sequential reading of multiple bytes without the need for repeated address selection.
• Write Protection: The WP pin can be used to protect the memory from accidental writes.
• Software Write Protection: Additional software-based protection mechanisms can be implemented to prevent unauthorized modifications.

Advantages and Disadvantages

Advantages

• Non-volatile storage: Data remains intact even during power loss.
• Easy to use: Simple interface and straightforward programming.
• Compact size: Small form factor suitable for space-constrained applications.
• High endurance: Can withstand a large number of write cycles.

Disadvantages

• Limited storage capacity: With only 1 kilobit of memory, it may not be suitable for applications requiring large amounts of data storage.
• Relatively slow write speed: EEPROMs generally have slower write speeds compared to other memory technologies.

Working Principles

The 24AA01H-I/S16K utilizes electrically erasable programmable read-only memory technology. It consists of a grid of memory cells that can be individually programmed or erased using electrical signals. The stored data is retained even when power is removed, making it ideal for non-volatile storage applications.
