Intersil 6-Phase Bidirectional DC/DC Controller for Automotive 12V-48V Power Supply Systems
Intersil Corporation has announced a 6-phase bidirectional PWM controller designed to perform buck and boost power conversions between 12V and 48V automotive buses. A single automotive-grade ISL78226 delivers up to 3.75kW and is able to interleave in a modular master/slave architecture. This allows for design of 48V hybrid powertrains that support internal combustion engine/electric mild hybrids.
The ISL78226 controller integrates a digital PMBus interface for system control, telemetry and diagnostics that support ISO 26262 functional safety requirements. The controller's limp-home mode reduces power in the event of a serious fault or failure.
The ISL78226 6-phase 12-48V bidirectional synchronous DC/DC controller is available now in a 10mm x 10mm, 64-lead TQFP package and is priced at $6.95 USD in 1k quantities. An ISL78226EVAL1Z evaluation board is also available. For more information, please visit the Intersil product website.

The PIC32MZ EF Development Board features a 200 MHz PIC32 microcontroller (MCU) with an integrated Wi-Fi module, designed for Internet of Things (IoT) and connectivity applications. The PIC32MX470 Development Board features a 120 MHz MCU and has been designed for audio, Bluetooth and other related generic applications. In addition, both the boards have USB connectors that can be used to develop USB host or device applications.
The Curiosity PIC32MZ EF Development Board (DM320104) is available starting December 2016 for USD $47.99. The Curiosity PIC32MX470 Development Board (DM320103) is available for $27.99.
Microsemi Achieves MIL-STD-883 Class B Qualification for RTG4 High-Speed Radiation-Tolerant FPGAs

aMicrosemi Corporation has announced its RTG4 radiation-tolerant field programmable gate arrays (FPGAs) have achieved MIL-STD-883 Class B qualification, meeting the industry's standard for qualifying microelectronic devices suitable for use within aerospace and defense electronic systems.
To achieve the new qualification, Microsemi's RTG4 FPGAs passed a series of environmental tests to determine resistance to deleterious effects of natural elements and conditions surrounding defense and space operations, as well as mechanical and electrical tests. RTG4 units from multiple wafer lots successfully completed 1,000-hour high temperature life tests as well.

RTG4's reprogrammable flash technology offers immunity to radiation-induced configuration upsets, without the configuration scrubbing required with SRAM FPGA technology. RTG4 supports space applications requiring up to 150,000 logic elements, and each includes a LUT4 and a flip-flop with triple module redundancy (TMR). The devices also feature total ionizing dose (TID) beyond 100 kilorads, as well as system performance of up to 300 MHz without single event transient (SET) mitigation.
The RTG4 Development Kit features Microsemi's Libero SoC Design Suite development tools for designing with Microsemi's radiation-tolerant FPGAs. RTG4 is Microsemi's latest development in radiation-tolerant FPGAs that are found in NASA and international space programs.
Xilinx Details New 16nm Virtex UltraScale+ FPGAs
Xilinx Inc. recently unveiled details for 16nm Virtex UltraScale+ FPGAs with HBM and CCIX technology. The new devices are architected to support the memory needs of compute-intensive applications such as machine learning, Ethernet connectivity, 8K video, and radar.
Detailed device tables and product documentation is available on all four new devices at the Xilinx product website.

WinSystems recently announced a line of single board computers with dual Ethernet featuring an Intel Atom E3900 Series Processor for Industrial IoT (IIoT) and other embedded systems. The PX1-C415 SBC is designed to capitalize on the latest-generation PCle/104 OneBank expansion, able to withstand temperatures ranging from -40°C to +85°C, while supporting the latest Microsoft Windows 10 and Linux OS’s. The PX1-C415 SBCs incorporate dual video interfaces, dual Ethernet ports, four serial ports, 24x bidirectional GPIO lines, and USB Type-C and M.2 connectors in a 4.5 square inch form factor.
The PX1-C415 series offers quad-core or dual-core System on Chip (SOC) for processing and graphics. It provides up to 8GB of DDR3-LV System RAM with support for error detection and correction. It accommodates up to two simultaneously active displays with interfaces available for DisplayPort and LVDS connections.
For networking and communications, the PX1-C415 series utilizes dual Intel i210IT Gigabit Ethernet interfaces, and provides eight USB 2.0 channels, one SuperSpeed USB 3.0 channel, four serial COM channels, 24 general purpose I/O (GPIO) lines, stereo audio and a watchdog timer.
Engineering units will be available early 2017 with full production targeted for Q2 2017.
