Product Overview

Category

AT24C256N-10SI belongs to the category of electrically erasable programmable read-only memory (EEPROM) chips.

Use

This product is commonly used for storing and retrieving digital information in electronic devices. It provides non-volatile storage, meaning that the data remains even when power is removed.

Characteristics

• High storage capacity: The AT24C256N-10SI has a capacity of 256 kilobits, allowing it to store a large amount of data.
• Serial interface: It utilizes a serial communication protocol, making it easy to integrate into various electronic systems.
• Low power consumption: The chip operates at low power levels, making it suitable for battery-powered devices.
• Reliable data retention: The EEPROM technology ensures that stored data remains intact for extended periods.

Package and Quantity

The AT24C256N-10SI comes in a small outline integrated circuit (SOIC) package. It is available in various quantities, typically sold in reels or tubes.

Specifications

• Operating voltage: 1.7V to 5.5V
• Maximum clock frequency: 1 MHz
• Write cycle time: 5 ms (maximum)

Functional Features

Memory Organization

The AT24C256N-10SI is organized into 32,768 pages, with each page containing 64 bytes. This allows for efficient storage and retrieval of data.

Sequential Read Operation

The chip supports sequential read operations, enabling the user to access consecutive memory locations without the need for repeated address input.

Write Protection

The WP pin can be used to protect the stored data from accidental modification. When WP is connected to VCC, write operations are disabled.

Advantages and Disadvantages

Advantages

• High storage capacity
• Low power consumption
• Reliable data retention
• Serial interface for easy integration

Disadvantages

• Limited maximum clock frequency
• Relatively slow write cycle time

Working Principles

The AT24C256N-10SI utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. It consists of a grid of memory cells that can be individually addressed and written to or read from using a serial communication protocol.

When data needs to be stored, the chip receives the address and data through the SDA pin. The data is then written to the specified memory location. During read operations, the chip retrieves the requested data and sends it back through the SDA pin.

Application Field Plans

The AT24C256N-10SI finds applications in various electronic devices, including but not limited to: - Consumer electronics: TVs, set-top boxes, digital cameras - Automotive systems: Infotainment systems, instrument clusters - Industrial equipment: Data loggers, control systems - Medical devices: Patient monitoring systems, diagnostic equipment
