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 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, IrDA, and Modbus modes.
New Microchip 32-bit Microcontroller Series Features Rich Peripheral Set; Large, Scalable Memory Configuration
Microchip Technology announced a new series of its low-cost, high pin count 32-bit PIC32 microcontrollers (MCUs).
By blending the key features of Microchip’s existing PIC32MX1/2 and PIC32MX5 MCU families, this latest PIC32MX1/2/5 MCU series delivers the benefits of a rich peripheral set for a wide range of cost-sensitive applications that require complex code and higher feature integration at a lower cost.
Based on magnetic Circular Vertical Hall (CVH) technology, the A1332 and A1334 devices, with their system-on-chip (SoC) architectures, provide fast output refresh rates and low signal path latency to support a wide variety of demanding automotive and industrial applications.
Both devices are ideal for automotive applications such as electronic power steering (EPS), transmission, motor position, throttle/pedal position, and other systems that require accurate measurement of angles.
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.
Designed to meet automotive industry requirements for temperature and humidity while offering consistent repeatability and stable performance, the Vishay Dale Thin Film devices feature a low standard TCR of ± 25 ppm/°C and laser-trimmed tolerances down to ± 0.1 %.
Featuring a tantalum nitride resistor film on a high-purity alumina substrate, the PAT resistors offer load-life stability of < 0.05 % at +70 °C for 1,000 hours and an ESD rating of 2 kV.
Infineon Launches ARM®-based Embedded Power Family for Smart Motor Control in Automotive Applications
Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) announced an ARM®-based Embedded Power family of bridge drivers offering an unmatched level of integration to address the growing trend towards intelligent motor control for a wide range of automotive applications.
As an industry first Infineon integrates on a single chip a high-performance microcontroller using the ARM® Cortex™-M3 processor, as well as the nonvolatile memory, the analog and mixed signal peripherals, the communication interfaces along with the MOSFET gate drivers. Thus, the Infineon Embedded Power family offers 32-bit performance in an application space that it is typically associated with 16-bit.
The NCV78763 advanced smart power ballast and dual channel LED driver provides an efficient single-chip automotive lighting solution capable of driving two strings of LEDs up to 60 volts (V).
A DC current of 1.6 amperes (A) can be supported on each output. The built-in current-mode voltage booster controller enables input current filtering. An internal pulse-width modulated (PWM) dimming function, covering frequencies up to 4 kilohertz (kHz), is also included in addition to the option of PWM direct-feed for full frequency and resolution control from the external microcontroller.
