Key Featrues

1024-Bit EEPROM Memory Organized into Four Pages: The DS2431 features 1024 bits of EEPROM memory divided into four pages of 256 bits each. This organization allows for flexible data storage and management, enabling applications like accessory identification, sensor calibration, and consumable tracking. The ability to write-protect individual pages or use EPROM-emulation mode enhances data security and reliability.
1-Wire Interface for Simplified Communication: The DS2431 utilizes a single-conductor 1-Wire interface, significantly reducing wiring complexity and cost in system designs. This minimalist interface supports communication at 15.4kbps or 125kbps, making it ideal for applications requiring low-cost, low-power data storage and retrieval, such as medical sensors or ink cartridge identification.
Wide Operating Voltage Range (2.8V to 5.25V): The device operates over a broad voltage range, ensuring compatibility with various power supplies and enhancing its versatility in different environments. This feature, combined with a wide temperature range (-40°C to +85°C), makes the DS2431 suitable for industrial and automotive applications where power and temperature conditions can vary significantly.
Individual Page Write Protection and EPROM-Emulation Mode: Each of the four memory pages can be permanently write-protected or set to EPROM-emulation mode, where bits can only transition from 1 to 0. This feature provides robust data integrity and security, making the DS2431 ideal for applications requiring tamper-proof data storage, such as calibration data or identification codes.
High ESD Protection and Noise Immunity: The DS2431 offers IEC 1000-4-2 Level 4 ESD protection (±8kV contact, ±15kV air) and includes switchpoint hysteresis and filtering to optimize performance in noisy environments. These features ensure reliable operation in harsh conditions, making the device suitable for industrial and automotive systems where electrical noise and ESD events are common.

Applications

Accessory/PC Board Identification: The DS2431 is ideal for uniquely identifying and managing accessories or PC boards in complex systems. Its 1-Wire interface simplifies integration, while the 1024-bit EEPROM allows for storing critical identification data, ensuring traceability and efficient inventory management in industrial and consumer electronics.
After-Market Management of Consumables: The DS2431 is perfect for tracking and managing after-market consumables, such as printer ink or toner cartridges. Its EPROM-emulation mode ensures data integrity, while the 1-Wire interface provides a cost-effective solution for embedding identification and usage data directly into consumable products.
Analog Sensor Calibration: The DS2431 is well-suited for storing calibration data in analog sensors, including IEEE 1451.4 smart sensors. Its ability to write-protect individual memory pages ensures the integrity of calibration data, while the 1-Wire interface simplifies communication in sensor networks across industrial and scientific applications.
Medical Sensor Calibration Data Storage: The DS2431 is an excellent choice for storing calibration data in medical sensors. Its robust 1-Wire interface and wide operating voltage range (2.8V to 5.25V) ensure reliable performance in medical environments, while the 1024-bit EEPROM provides ample space for critical calibration and identification data.
