Description
The DS28E01P-100+ is a 1-Wire EEPROM (Electrically Erasable Programmable Read-Only Memory) device designed by Maxim Integrated. It features 1024 bits (128 bytes) of memory and uses a single data line with minimal extra circuitry, making it ideal for space-constrained applications. The EEPROM allows for individual byte write operations and requires no external power source apart from the 1-Wire bus.
Key features include its unique, factory-programmed 64-bit ROM ID for secure authentication and device addressing, as well as a high-speed operation capability up to 15.4 kbit/s. The DS28E01P-100+ offers robust security features, including a challenge-and-response SHA-1 computation based on a secret key stored within the device. This makes it suitable for secure authentication, data protection, and anti-counterfeiting applications in various industries.
The small, 6-pin TSOC package ensures easy integration into existing systems. Typical applications include accessory and peripheral identification, medical sensor calibration, and consumable identification in printers and other consumer electronics.
