DS28E30 is a one-wire connected secure authenticator from ADI, intended to help protect products from counterfeiting or misuse, while being simple to add. Each part is factory programmed with ADI public key certificate to guarantee authenticity. It includes a FIPS 186 elliptic curve digital signature algorithm (ECDSA), secure storage of keys and secure storage of application data – comminicating with ...

Diodes is claiming “the world’s smallest crystal oscillator family” for the 2 x 2.5mm UF252 series. These are LVPECL output devices which come in 2.5V and 3.3V supply versions all with low jitter to suit them to high performance equipment. Maximum (RMS) phase jitter can be as low as 0.07ps (3.3V, 156.25MHz, 12kHz-20MHz offset, 0.05ps typical) for the highest grade versions. ...

Nexperia is claiming to have developed the world’s smallest SD Card level translator IC, housed in a 1.45 x 1.45 x 0.45mm 16bump wafer-level chip-scale package with a bump pitch of 0.35mm. Called NXS0506UP, it can be clocked at up to 208MHz (104Mbit/s) and is an SD 3.0-compliant bi-directional dual voltage level translator with auto-direction control, EMI filtering and IEC 61000-4-2 ...

NXP has combined NFC, secure authentication, anti-tamper and a sensor interface into a single battery-free chip family called NTAG 22x. The parts are aimed high-volume tagging applications, for example: authenticating retail products or protecting them from tampering, or battery-free environment sensing. They include ISO/IEC 14443-A communication and function as an NFC Forum Type 2 tag, and include AES-128 cryptography and CC EAL3+ ...

The ePower chipset family of 100V, 65A IC chipsets integrate a 100V EPC23101 eGaN driver and EPC2302 eGaN FET. Developed by Efficient Power Conversion (EPC), they reduce the solution size for high power density applications, including 48V DC-DC conversion in computing and brushless DC (BLDC) motor drives for e-mobility, robotics and drones. The ePower chipset is capable of a maximum withstand voltage of 100V, ...

Diodes has introduced a pair of level-shifting IO port expanders with automotive qualification to AEC-Q100 Grade 2. Both interface to the host controller though a variable voltage I2C interface and interface to the outside world thorough variable voltage IO pins. The thresholds for the I2C-bus interface are set by a reference voltage input, intended to be connected directly to the Vdd ...

Microchip is introducing touchscreen controllers certified to IEC/UL 60730 Class B, that will work on displays over 10in across. Called MXT448UD-HA and MXT640UD-HA (32 x 20 touch array) , they are also compliant with IEC61000-4-6 Class A for conducted noise immunity up to 10Vrms (level three for industrial use). “This enables products with a touch screen interface to function in very ...

Gowin GoBridge is a family of bridging chips that convert a USB interface to different serial and parallel busses. “The GWU2X family enables conversion between USB and four peripheral interfaces: JTAG, SPI, I2C and GPIO; while the GWU2U series is suitable for conversion between USB and UART,” according to distributor Rutronik, which is stocking the parts. “This provides Gowin with ...

STMicroelectronics’ has started selling one of its machine-to-machine communication ST4SIM embedded SIM ICs through its e-store. Prior to this, ST4SIM parts were only available to selected customers. “Mass-market availability now lets developers everywhere leverage secure and flexible cellular connectivity in more applications than ever, including independent M2M development, proof-of-concept, and prototype projects,” said ST marketing director Laurent Degauque. The e-store ...

Microchip has boosted the performance of its ‘chip-scale atomic clocks’, offering wider operating temperature, faster warm-up and improved extreme environment frequency stability in its SA65 model. The whole frequency source fits inside 41 x 36 x 12mm (plus pins) which is 17cm3. It weighs 35g. SA65 operates over -40 to 80°C (-55 to 105°C storage) and warms up in two minutes at ...
