Maxim Integrated DS2432P-W01+1T Product Overview

The DS2432P-W01+1T is a high-quality integrated circuit from Maxim Integrated, designed for secure authentication and memory storage applications. This chip is part of the renowned family of 1-Wire® devices that Maxim Integrated offers, which are known for their ability to communicate through a single data line (plus ground) for simplified connectivity. This feature is particularly useful in applications where minimal wiring is a priority and space is at a premium.

At the heart of the DS2432P-W01+1T is a 1024-bit, write-once read-many (WORM) EEPROM memory. This memory is partitioned into four pages of 256 bits each, providing a flexible data storage solution for a variety of applications. The write-once feature ensures that once data is written to a memory page, it cannot be altered or tampered with, making the DS2432P-W01+1T an ideal choice for storing sensitive or critical information.

In addition to its memory capabilities, the DS2432P-W01+1T offers a robust suite of security features. It incorporates a factory-programmed 64-bit registration number that serves as a unique identifier, ensuring that each device is distinct. This registration number is coupled with a 160-bit secret, user-programmable secure hash algorithm (SHA-1) that provides a high level of data integrity and authentication. This makes the DS2432P-W01+1T particularly suitable for anti-counterfeiting and system security purposes.

The device operates over a wide voltage range of 2.8V to 5.25V and is specified for operation from -40°C to +85°C, making it reliable under varying environmental conditions. Its small form factor, available in the TO-92 package, allows for easy integration into system designs without requiring significant board space.

Overall, the DS2432P-W01+1T by Maxim Integrated is a powerful and secure solution for applications that require reliable data storage and protection against unauthorized access and duplication. Its combination of a unique ID, secure memory, and user-programmable SHA-1 engine makes it a strong candidate for safeguarding product authenticity and protecting intellectual property.
