DS28E01P-100+TR规格书详情
General Description
The DS28E01-100 combines 1024 bits of EEPROM with challenge-and-response authentication security implemented with the ISO/IEC 10118-3 Secure Hash Algorithm (SHA-1). The 1024-bit EEPROM array is configured as four pages of 256 bits with a 64-bit scratch pad to perform write operations. All memory pages can be write protected, and one page can be put in EPROM-emulation mode, where bits can only be changed from a 1 to a 0 state. Each DS28E01-100 has
its own guaranteed unique 64-bit ROM registration number that is factory lasered into the chip. The DS28E01-100 communicates over the single-contact 1-Wire®bus. The communication follows the standard 1-Wire protocol with the registration number acting as the node address in the case of a multidevice 1-Wire network.
Features
♦1024 Bits of EEPROM Memory Partitioned Into Four Pages of 256 Bits
♦On-Chip 512-Bit SHA-1 Engine to Compute 160-Bit Message Authentication Codes (MACs) and to Generate Secrets
♦Write Access Requires Knowledge of the Secret and the Capability of Computing and Transmitting a 160-Bit MAC as Authorization
♦User-Programmable Page Write Protection for Page 0, Page 3, or All Four Pages Together
♦User-Programmable OTP EPROM Emulation Mode for Page 1 (“Write to 0”)
♦Communicates to Host with a Single Digital Signal at 15.3kbps or 90.9kbps Using 1-Wire
Protocol
♦Switchpoint Hysteresis and Filtering to Optimize Performance in the Presence of Noise
♦Reads and Writes Over 2.8V to 5.25V Voltage Range from -40°C to +85°C
♦6-Lead TSOC and TDFN or 2-Lead TO-92 and SFN Packages
Applications
Printer Cartridge Configuration and Monitoring
Medical Sensor Authentication and Calibration
System Intellectual Property Protection
