NXP Semiconductors has announced hardware secure element certified to FIPS 140-3 Level 3. “SE052F combines the flexibility of a secure element with the newest generation of the Federal Information Processing Standard, a US and Canadian federal standard for data security required by NIST for participation in federal projects,” said NXP. “Many industrial IoT device manufacturers are turning to certifications, such ...

Texas Instruments has introduced a hex level translator for logic that can also be used as a line-driver. Called SN74LV6T17-EP and part of the LVxT logic family, it contains six independent buffers with Schmitt-trigger inputs. The output level is referenced to the supply voltage, which can span 1.6 to 5.5V and supports 1.8, 2.5, 3.3 and 5V cmos levels. The ...

Würth Elektronik has introduced two families of surface-mount multi-channel galvanic isolators for digital signals. Devices in the WPME-CDIP family have four 100Mbit/s isolated channels and a built-in dc-dc converter that provides isolated power from one side to the other. Different versions have different combinations of digital isolator directions: all from input to output, three in that direction and one returning, ...

Infineon has created a 10Gbit/s USB peripheral controller, intended to be used in devices that connect to a host via USB-C. Called CYUSB4014-BZXI, it has an Arm Cortex-M4 processing core, a Cortex-M0+, 1,024kbyte of ram and 512kbyte of flash. Alongside USB-C, it has LVDS, LVCMOS and QSPI serial interfaces, and a crypto processor. This is actually one of four in ...

Diodes has created a series of automotive-compliant PCI Express 3.0 packet switches for in-vehicle networking. “The architecture used enables flexible port configuration with upstream, downstream and CDEP [cross-domain end-point] ports being assigned according to requirements,” according to the company. “They can connect with up to seven different endpoints and support multi-host applications.” PI7C9X3G606GPQ offers 6-port/6-lane operation, PI7C9X3G808GPQ 8-port/8-lane and PI7C9X3G816GPQ ...

Toshiba has introduced a series of multi-channel digital signal isolators that “ensuring stable high-speed digital communications even in the toughest factory floor environments”, it claims. They have 100kV/μs minimum common-mode transient immunity (1.5kV common-mode, 25°C), and carry data rates up to 150Mbit/s. Isolation is 5kV for 1 minute. Called the DCL54xx01 series, they are four-channel devices with different combinations of ...

At Embedded World today, Microchip announced six secure authentication devices that meet Common Criteria Joint Interpretation Library (JIL) secure key storage, and support algorithms that comply with the Federal Information Processing Standard (FIPS). They are intended to be companion devices, compatible with any microprocessor or microcontroller. “This portfolio lowers the barrier to entry and enables developers of products for new ...

STMicroelectronics has created a fast dual-channel high-speed digital isolator with both channels in the same direction. Called STISO620, it s”6kV thick-oxide technology ensures robust galvanic isolation”, according to the company. “Built to maintain insulation integrity during system faults and with ageing, they enhance reliability in industrial and consumer applications.” Peak withstanding is 4kVpk, isolation is to 2.83kVrms, and maximum working is ...

Shortly after Infineon launched its XMC7000 microcontroller series at electronica 2022, Rutronik has added the single- and dual-core devices to its portfolio. The microcontrollers have dual-bank flash memory for over the air (OTA) updates via read-while-write (RWW). The series consists of Arm Cortex-M7 core microcontrollers with Arm Cortex-M0+ support. It has a dual-bank flash whereby an update can be loaded ...

STMicroelectronics has created a pair of 10W Class-D audio amplifiers for use in vehicles “for automotive applications like eCall, telematics and wherever an audio channel needs to reproduce human voice, music or warning messages “, it said. They are almost identical, both offering a digital (I2S) front end, digital core, 24bit DAC (100dB resolution), a Class-D trans-resistance PWM output stage ...
