| Evaluation and Demonstration Boards and Kits | 10 | Active | The DS28E05 is a 112-byte user-programmable EEPROM organized as 7 pages of 16 bytes each. Memory pages can be individually set to write protected or EPROM emulation mode through protection byte settings. Each part has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip. The DS28E05 communicates over Maxim Integrated's single contact 1-Wire®interface at overdrive speed with the ROM ID acting as node address in the case of a multiple-device 1-Wire network.ApplicationsAccessory/PCB IdentificationAftermarket Management of ConsumablesAnalog Sensor CalibrationMedical Sensor Calibration Data Storage |

DS28E15DeepCover Secure Authenticator with 1-Wire SHA-256 and 512-Bit User EEPROM | Specialized ICs | 11 | Active | DeepCover®embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.The DeepCover Secure Authenticator (DS28E15) combines secure challenge and response authentication functionality based on the FIPS180-3 specified Secure Hash Algorithm (SHA-256) with 512 bits of user-programmable EEPROM. Additional secure memory holds a secret/key for SHA-256 operations. Each device has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip. The DS28E15 generates the SHA-256 message authentication code (MAC) computed from data in the user memory, the SHA-256 secret, a host controller random challenge, and the 64-bit ROM ID. A secure and low-cost factory-programming service is available to preprogram device data including the SHA-256 secret. The DS28E15 communicates over Maxim's single-contact 1-Wire®bus.ApplicationsAuthentication of ConsumablesSecure Feature Control |
DS28E161-Wire Secure SHA-3 Authenticator | Development Boards, Kits, Programmers | 8 | Active | The DS28E16 secure authenticator combines FIPS202-compliant Secure Hash Algorithm (SHA-3) challenge and response authentication with secured EEPROM.The device provides a core set of cryptographic tools derived from integrated blocks including a SHA-3 engine, 256 bits of secured user EEPROM, a decrement-only counter and a unique 64-bit ROM identification number (ROM ID). The unique ROM ID is used as a fundamental input parameter for cryptographic operations and serves as an electronic serial number within the application. The device communicates over the single-contact 1-Wire® bus. The communication follows the 1-Wire protocol with the ROM ID acting as node address in the case of a multidevice 1-Wire network.ApplicationsAccessory and Peripheral Secure AuthenticationBattery Authentication and Charge Cycle TrackingMedical Tools/Accessories Authentication and Calibration |
DS28E171-Wire®-to-I2C Master Bridge | Evaluation and Demonstration Boards and Kits | 3 | Active | The DS28E17 is a 1-Wire slave to I2C master bridge device that interfaces directly to I2C slaves at standard (100kHz max) or fast (400kHz max). Data transfers serially by means of the 1-Wire®protocol, which requires only a single data lead and a ground return. Every DS28E17 is guaranteed to have a unique 64-bit ROM registration number that serves as a node address in the 1-Wire network. Multiple DS28E17 devices can coexist with other devices in the 1-Wire network and be accessed individually without affecting other devices. The DS28E17 allows using complex I2C devices such as display controllers, ADCs, DACs, I2C sensors, etc. in a 1-Wire environment. Each self-timed DS28E17 provides 1-Wire access for a single I2C interface.ApplicationsAccessory Identification and ControlADCs/DACsDisplay ControllersI2C Sensors |
DS28E181-Wire®to I2C/SPI Bridge with Command Sequencer | Controllers | 3 | Active | The DS28E18 is a simple communications bridge that resides at a remote SPI or I2C sensor and allows the sensor to be controlled by just two wires coming from the host system. It reduces the wire count from six (for SPI) or four (for I2C). These two wires use Analog Devises' 1-Wire protocol that combines power and signal on a single wire, and which is driven by the programmable I/O pins on the host's microcontroller. The 1-Wire network supports connection lengths up to 100m and 10 sensor nodes or more.The IC provides a 512-byte command sequencer in SRAM that can be loaded with multiple I2C or SPI commands. Once loaded, the host controller sends a command to execute the sequence, power, and collect data from attached I2C or SPI peripherals. A subsequent 1-Wire command reads collected data. Power for attached sensors or peripherals is sourced from the 1-Wire line making the DS28E18 a very efficient solution to remotely power and control complex I2C or SPI devices such as sensors, ADCs, DACs, and display controllers.When used as a bridge for I2C slave devices, the DS28E18 communicates at Standard mode (100kHz), Fast mode (400kHz) or Fast-mode Plus (Fm+, 1MHz). In SPI mode, multiple clock rates are supported up to 2.3MHz. Configuring for I2C or SPI operation is performed with a 1-Wire command; I2C is the power-on default. When operating in I2C mode, two programmable GPIO pins are available for additional peripheral control.Each DS28E18 provides a unique and secure 64-bit ROM identification number (ROM ID) that serves as the device's address on the 1-Wire bus. Multiple DS28E18 devices can coexist with other devices in a 1-Wire network and be accessed individually without affecting other devices.ApplicationsAccessory Identification and ControlEquipment Configuration and MonitoringExamining Environmental ConditionsGrain Elevator Monitoring |
