DS28EA001-Wire Digital Thermometer with Sequence Detect and PIO | Temperature Sensors | 2 | Active | The DS28EA00 is a digital thermometer with 9-bit (0.5°C) to 12-bit (1/16°C) resolution and alarm function with nonvolatile (NV), user-programmable upper and lower trigger points. Each DS28EA00 has its unique 64-bit registration number that is factory-programmed into the chip. Data is transferred serially through the 1-Wire® protocol, which requires only one data line and a ground for communication. The improved 1-Wire front end with hysteresis and glitch filter enables the DS28EA00 to perform reliably in large 1-Wire networks. Unlike other 1-Wire thermometers, the DS28EA00 has two additional pins to implement a sequence detect function. This feature allows the user to discover the registration numbers according to the physical device location in a chain, e.g., to measure the temperature in a storage tower at different height. If the sequence detect function is not needed, these pins can be used as general-purpose input or output. The DS28EA00 can derive the power for its operation directly from the data line ("parasite power"), eliminating the need for an external power supply.ApplicationsAny Rack-Based Electronic SystemClimate ControlData communication equipmentProcess Temperature MonitoringServersWireless Basestations |
| Integrated Circuits (ICs) | 6 | Active | The DS28EC20 is a 20480-bit, 1-Wire®EEPROM organized as 80 memory pages of 256 bits each. An additional page is set aside for control functions. Data is written to a 32-byte scratchpad, verified, and then copied to the EEPROM memory. As a special feature, blocks of eight memory pages can be write protected or put in EPROM-Emulation mode, where bits can only be changed from a 1 to a 0 state. The DS28EC20 communicates over the single-conductor 1-Wire bus. The communication follows the standard 1-Wire protocol. Each device has its own unalterable and unique 64-bit ROM registration number. The registration number is used to address the device in a multidrop 1-Wire net environment.ApplicationsCard/Module Identification in Rack-Based SystemsDevice AuthenticationIEEE 1451.4 SensorsInk and Toner Cartridge IDMedical and Industrial Sensor Identification/CalibrationPCB IdentificationSmart Cable |

DS28S60DeepCover Cryptographic Coprocessor with ChipDNA | Evaluation Boards | 3 | Active | The DS28S60 DeepCover®cryptographic coprocessor easily integrates into embedded systems enabling confidentiality, authentication and integrity of information. With a fixed command set and no device-level firmware development required, the DS28S60 makes it fast and easy to implement full security for IoT devices. Communication with the device is performed using the industry-standard SPI slave interface at up to 20Mbps with a simple set of commands that provide a comprehensive security toolbox utilizing hardware-based cryptographic blocks. As a co-processor to an SPI-interfaced host controller, the command functionality includes ECDSA-P256 signature and verification, SHA-256 based digital signature, AES-128 packet encryption/decryption, ECDHE key exchange for session key generation, and access to high-quality random numbers. An NIST SP800-90B compliant true random number generator (TRNG) is integrated for on-chip cryptographic operations as well as providing random data and nonces to the host controller, if required. Nonvolatile storage for secrets, certificates, public/private keys, and application-specific sensitive data is supported with 3.6KB of secured flash memory.The DS28S60 integrates Maxim’s patented ChipDNA™ feature, a physically unclonable function (PUF) to provide a cost-effective solution with the ultimate protection against security attacks. Using the random variation of semiconductor device characteristics that naturally occur during wafer fabrication, the ChipDNA circuit generates a unique output value that is repeatable over time, temperature, and operating voltage. Attempts to probe or observe ChipDNA operation modifies the underlying circuit characteristics, preventing discovery of the unique value used by the chip's cryptographic functions. ChipDNA output is utilized as key content to cryptographically secure all device-stored data.ApplicationsEnd-Point AuthenticationEnd-to-End EncryptionInternet of Things (IoT) Device SecurityKey Management and ExchangePrevention of Counterfeit Products |
