The ADuM3200 / ADuM3201 are dual-channel, digital isolatorsbased on the Analog Devices, Inc., iCoupler® technology.Combining high speed CMOS and monolithic transformertechnology, these isolation components provide outstandingperformance characteristics superior to alternatives such asoptocoupler devices.By avoiding the use of LEDs and photodiodes, iCouplerdevices remove the design difficulties commonly associatedwith optocouplers. The typical optocoupler concerns regardinguncertain current transfer ratios, nonlinear transfer functions,and temperature and lifetime effects are eliminated with thesimple iCoupler digital interfaces and stable performance characteristics.The need for external drivers and other discretecomponents is eliminated with these iCoupler products. Furthermore,iCoupler devices consume one-tenth to one-sixth thepower of optocouplers at comparable signal data rates.The ADuM3200 / ADuM3201 isolators provide two independentisolation channels in a variety of channel configurations anddata rates (see the Ordering Guide). They operate with 3.3 Vor 5 V supply voltages on either side, providing compatibilitywith lower voltage systems as well as enabling voltage translationfunctionality across the isolation barrier. The ADuM3200Wand ADuM3201W are automotive grade versions qualifiedfor 125°C operation.In comparison to the ADuM1200 / ADuM1201 isolators, theADuM3200 / ADuM3201 isolators contain various circuit andlayout changes to provide increased capability relative to system-levelIEC 61000-4-x testing (ESD, burst, and surge). The precisecapability in these tests for either the ADuM1200 / ADuM1201or ADuM3200 / ADuM3201 products is strongly determined bythe design and layout of the user’s board or module.

The DS28C36 is a DeepCover® secure authenticator that provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security functions. In addition to the security services provided by the hardware implemented crypto engines, the device integrates a FIPS/NIST true random number generator (RNG), 8Kb of secured EEPROM, a decrement-only counter, two pins of configurable GPIO, and a unique 64-bit ROM identification number (ROM ID).The ECC public/private key capabilities operate from the NIST defined P-256 curve and include FIPS 186 compliant ECDSA signature generation and verification to support a bidirectional asymmetric key authentication model. The SHA-256 secret-key capabilities are compliant with FIPS 180 and are flexibly used either in conjunction with ECDSA operations or independently for multipleHMAC functions.Two GPIO pins can be independently operated under command control and include configurability supporting authenticated and nonauthenticated operation including an ECDSA-based crypto-robust mode to support secure-boot of a host processor.DeepCover embedded security solutions cloak sensitive data under multiple layers of advanced security to provide the most secure key storage possible. To protect against device-level security attacks, invasive and noninvasive countermeasures are implemented including active die shield, encrypted storage of keys, and algorithmic methods.Explore security topics and test drive secure authenticators with the Maxim Security Lab Secure Boot and Secure Download - Part 1: Protecting IoT Devices with Secure Authentication Secure Boot and Secure Download - Part 3: Using the DS28C36 Secure Boot and Secure Download - Part 2: Technologies Behind Embedded Security ApplicationsAccessory and Peripheral Secure AuthenticationIoT Node Crypto-ProtectionSecure Boot or Download of Firmware and/or System ParametersSecure Storage of Cryptographic Keys for a Host Controller

The DS28E38 is an ECDSA public key-based secure authenticator that incorporates Maxim’s patented ChipDNA™ PUF technology. ChipDNA technology involves a physically unclonable function (PUF) that enables the DS28E38 to deliver cost-effective protection against invasive physical 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 cryptographic functions. The DS28E38 utilizes the ChipDNA output as key content to cryptographically secure all device stored data and optionally, under user control, as the private key for the ECDSA signing operation. With ChipDNA capability, the device provides a core set of cryptographic tools derived from integrated blocks including an asymmetric (ECC-P256) hardware engine, a FIPS/NIST-compliant true random number generator (TRNG), 2Kb of secured EEPROM, a decrement-only counter and a unique 64-bit ROM identification number (ROM ID). The ECC public/ private key capabilities operate from the NIST-defined P-256 curve to provide a FIPS 186-compliant ECDSA signature generation function. 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 DS28E38 communicates over the single-contact 1-Wire® bus at both standard and overdrive speeds. The communication follows the 1-Wire protocol with the ROM ID acting as node address in the case of a multidevice 1-Wire network.Sample now!Explore security topics and test drive secure authenticators with the Maxim Security LabRead white paper › Read white paper ›How to Setup the DS28E38 Evaluation Kit and Perform ECDSA Authentication ChipDNA–Defend Your IoT Designs from HackersAlso see: ChipDNA Technology ›ApplicationsAuthentication of Medical Sensors and ToolsIoT Node AuthenticationPeripheral AuthenticationPrinter Cartridge Identification and AuthenticationReference Design License ManagementSecure Management of Limited Use Consumables
