A Network Enforcement Module (NEM™) designed by Battelle to detect cybersecurity threats in today’s increasingly connected vehicles has successfully completed field trials with several automakers and is ready for commercialization.

The dramatic increase in automotive Internet connectivity to other devices and the Internet provides more entry points to the vehicle’s electronic systems and hackers have taken notice. Vehicles today can have as many as 100 microprocessor-based Electronic Control Units (ECUs) networked together to coordinate and control critical systems such as air bags, infotainment, active cruise, park assist and active steering.

STMicroelectronics’ latest STM32F091 ARM® Cortex®-M0 microcontroller overcomes the resource constraints imposed by similar devices positioned for cost-sensitive applications by providing large on-chip memories and up to eight USARTs[1] that save multiplexing communication ports in applications such as in-car audio or three-phase power metering.

With up to 256Kbytes of Flash on-chip and a 32Kbyte SRAM — enough to implement a Java stack — the STM32F091 can host applications that deliver user experiences normally associated with larger or more expensive devices. All variants, including those in economical 48-pin packages, have at least six USARTs. Three of the USARTs are able to support smartcard, LIN[2], IrDA[3], and Modbus[4] modes.

STMicroelectronicsSTMicroelectronics Supports Drive for Inverters in Smaller Boxes Everywhere, from PHEV Battery Chargers to Solar Generators

New silicon-carbide (SiC) diodes feature increased surge-versus-normal current rating

STMicroelectronics (NYSE: STM) has revealed new automotive-qualified silicon-carbide (SiC) diodes for advanced on-board battery chargers (OBCs) in electric vehicles such as Plug-in Hybrids (PHEVs) that demand high power-handing capability within a confined space.

Smaller Power Modules

These diodes allow designers to build smaller power modules, which is good for automotive applications and makes them also a strong choice for tackling the Little Box Challenge presented by Google and IEEE. ST is a device-manufacturer partner of this new $1 million competition to design kW-scale inverters that are more than ten-times smaller than today’s inverters for various applications, particularly solar micro-generators.
