series introduction

# DS28CM00 Product Series Introduction

## 1. Overview
The DS28CM00 product series is a remarkable offering in the realm of electronic components, specifically designed to meet a wide range of application requirements with high - precision and reliability. Developed by a leading semiconductor manufacturer, these devices are engineered to provide unique identification and secure data storage capabilities, making them an ideal choice for various industries such as industrial automation, consumer electronics, and automotive.

## 2. Key Features

### 2.1 Unique 64 - Bit Serial Number
Each DS28CM00 device comes with a factory - programmed, unique 64 - bit serial number. This serial number serves as a distinct identifier for the device, enabling easy tracking and management in large - scale systems. In industrial applications, for example, it can be used to identify individual sensors or actuators, facilitating inventory management and maintenance scheduling.

### 2.2 One - Wire Interface
The DS28CM00 utilizes a single - wire communication interface. This simplifies the hardware design by reducing the number of required pins and wiring, which is especially beneficial in space - constrained applications. The One - Wire interface also allows multiple DS28CM00 devices to be connected in a daisy - chain configuration, enabling efficient communication with a microcontroller or other host devices.

### 2.3 Low Power Consumption
These devices are designed with low power consumption in mind. They can operate in a wide range of power supply voltages, typically from 2.8V to 5.25V, and consume minimal power during both active and standby modes. This makes them suitable for battery - powered applications, such as portable medical devices and wireless sensors, where power efficiency is crucial for extending battery life.

### 2.4 High - Temperature Operation
The DS28CM00 product series is capable of operating in high - temperature environments. With an operating temperature range of - 40°C to + 85°C, these devices can withstand harsh industrial and automotive conditions. This high - temperature tolerance ensures reliable performance in applications such as engine management systems and industrial ovens.

### 2.5 Tamper - Resistant Design
To enhance security, the DS28CM00 devices feature a tamper - resistant design. The unique serial number is stored in a non - volatile memory that is protected against unauthorized access and modification. This makes them suitable for applications where data integrity and security are of utmost importance, such as access control systems and payment terminals.

## 3. Applications

### 3.1 Industrial Automation
In industrial automation, the DS28CM00 can be used to identify and authenticate individual components in a production line. For example, it can be integrated into programmable logic controllers (PLCs), sensors, and actuators to ensure that only authorized devices are used in the system. This helps to prevent counterfeiting and improve the overall reliability of the automation process.

### 3.2 Consumer Electronics
In consumer electronics, the DS28CM00 can be used for product authentication and anti - counterfeiting purposes. For instance, it can be incorporated into smartphones, tablets, and other portable devices to verify the authenticity of accessories such as chargers and headphones. This protects consumers from using low - quality or counterfeit products that may pose a safety risk.

### 3.3 Automotive
In the automotive industry, the DS28CM00 can be used for vehicle component identification and tracking. It can be integrated into engine control units (ECUs), sensors, and other critical components to ensure proper functioning and traceability. Additionally, the high - temperature tolerance of these devices makes them suitable for use in harsh automotive environments.

### 3.4 Medical Devices
In medical devices, the DS28CM00 can be used for device identification and patient data
