The new automotive MCUs combine compliance with the most stringent automotive safety standards, encryption for security, and increased memory size for the storage of vital programs and data, strengthening ST’s product line of fault-tolerant microcontrollers for demanding applications throughout the car. These mission-critical applications include engine management, transmission, anti-lock braking, electric power steering, active suspension, and advanced driver assistance systems (ADAS).
“Security and functional safety compliance are essential to realizing cutting-edge high-reliability System-on-Chip ICs for mission-critical automotive applications,” said Fabio Marchio, Group Vice President, General Manager of ST’s Automotive Microcontroller & Infotainment Division. “Offering a simple and compelling upward-migration path from existing parts, our new automotive MCUs enable improved vehicle performance and economy with no compromises in security, while delivering savings in development by promoting hardware and software reuse.”
Part of ST’s Power Architecture™ single-chip 32-bit automotive-MCU family, the SPC58NE product line combines multiple high-performance dual-issue cores with up to 6MB Flash and 768kB internal RAM memory, eight CAN (Controller Area Network) interfaces, and an optimized peripheral set based on the end application. The multiple cores ensure redundancy in these most-important applications to meet the safety and security demands of vehicle manufacturers—and consumers.
The SPC58NE product line is currently available in BGA 292 and LQFP176 package configurations. KGD versions are also planned in the near future. Compliant with the ISO 26262 ASIL-D and EVITA Medium class, the SPC58NE84 is sampling now.
SPC58NE84E7 32-bit Power Architecture MCU for High Performance Applications
SPC58NExx family is the first member of the new SPC58NExx family of 32-bit Flash Automotive MCUs offering a hardware based solution able to answer both ISO26262 ASIL-D compliant and high-performance real-time system requirements for mid/high-end powertrain applications.

STMicroelectronics Unveils New Automotive Serial EEPROMs Offering Industry’s Best Choice of Densities in Tiny 2x3mm Outline
Automotive-qualified serial EEPROMs from STMicroelectronics provide the industry’s largest selection of densities in the tiny 2mm x 3mm WFDFPN8 package, giving engineers maximum flexibility when designing highly integrated body controllers and gateways, as well as radar and camera modules for Advanced Driver Assistance Systems (ADAS).
The WFDFPN8 outline has already proved popular in consumer-electronics applications, and ST has now created a rugged version capable of withstanding automotive environments. The devices have passed AEC-Q100 grade 0 reliability criteria tests and operate up to 125°C. Further advantages include 4ms write time allowing fast parameter storage; clock frequency up to 20MHz allowing rapid data exchanges; and built-in traceability and security features. These include a dedicated page for software identification and a write-lockable page to keep sensitive data secure.

Offline controller for LED lighting with constant voltage primary-sensing and high power factor.
The HVLED001 is an enhanced peak current mode controller capable of controlling mainly high power factor (HPF) flyback or buck-boost topologies in LED drivers having an output power up to 150 W. Some other topologies, like buck, boost and SEPIC can also be implemented.
ST’s innovative high voltage technology allows direct connection of the HVLED001 to the input voltage in order to both start up the device and monitor the input voltage without the need for external components.
Advanced features are embedded to control either the output voltage or output current precisely and reliably using a reduced number of components, mainly passive. Startup and light-load conditions are managed by dedicated operating schemes to improve the quality of output variable regulation in the final application. Abnormal conditions such as open circuit, output short-circuit, input overvoltage/undervoltage, and circuit failures such as open loop and overcurrent of the main switch are effectively controlled.
A smart auto-recover timer (ART) function is built in to guarantee automatic application recovery, without loss of reliability.

|STMicroelectronics’ STEVAL-MKI165V1 is an adapter board designed to facilitate the evaluation of MEMS devices in the LPS25HB product family. The board offers an effective solution for fast system prototyping and device evaluation directly within the user’s own application. The STEVAL-MKI165V1 can be plugged into a standard DIL 24 socket. The adapter provides the complete LPS25HB pinout and comes ready-to-use with the required decoupling capacitors on the VDD power supply line. This adapter is supported by the STEVAL-MKI109V2 motherboard which includes a high-performance 32-bit microcontroller functioning as a bridge between the sensor and a PC. It’s possible to use the downloadable graphical user interface (Unico GUI), or dedicated software routines for customized applications.|

|The new SCT20N120 silicon-carbide power MOSFET from STMicroelectronics brings advanced efficiency and reliability to a broader range of energy-conscious applications such as inverters for electric/hybrid vehicles, solar or wind power generation, high-efficiency drives, power supplies, and smart-grid equipment.
ST is among the few vendors leading the development of the robust and efficient silicon-carbide power semiconductors. The 1200V SCT20N120 extends the family, with on-resistance (RDS(ON)) better than 290mΩ all the way to the 200°C maximum operating junction temperature. Switching performance is also consistent over temperature thanks to highly stable turn-off energy (Eoff) and gate charge (Qg). The resulting low conduction and switching losses, combined with ultra-low leakage current, simplify thermal management and maximize reliability.
