DS28E01X-100规格书详情
GENERAL DESCRIPTION
The DS28E01-100 combines1024 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 scratchpad 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 Dallas Semiconductor 1-Wire protocol with the registration number acting as node
address in the case of a multi-device 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 (MAC) 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 15.3k bits or 125k bits per second using 1-Wire protocol
Switchpoint Hysteresis and Filtering to Optimize Performance in the Presence of Noise
Reads and writes over a wide voltage range of 2.8V to 5.25V from -40°C to +85°C
6-lead TSOC, 2-lead SFN or solder-bumped chipscale surface mount package
APPLICATIONS
Printer Cartridge Configuration and Monitoring
Medical Sensor Authentication and Calibration
System Intellectual Property Protection
