MCUs with EtherCAT Target Industrial Applications
Renesas Electronics has introduced the RX72M Group of RX MCUs featuring an EtherCAT slave controller for industrial Ethernet communication. The new product group offers a high-performance, single-chip MCU solution with large memory capacities for industrial equipment requiring control and communication functions such as compact industrial robots, programmable logic controllers, remote I/O and industrial gateways. According to Renesas, the use of EtherCAT in industrial Ethernet is growing fast, and is currently used on dedicated MCUs, ICs and high-end SoC devices specialized for EtherCAT communication. The new RX72M Group achieves a 1396 CoreMark score at 240 MHz as measured by EEMBC Benchmarks, and it is capable of both application processing and EtherCAT communication.

Arm Cortex M23-Based MCUs FeatureFreeRTOS Kernel Support
Nuvoton Technology has announced that it is demonstrating the capability of FreeRTOS kernel support with the NuMicro M2351 Series MCU. According to the company, the M2351 is one of the first Arm Cortex-M23 based MCUs that has a preconfigured example that embedded developers can use to run FreeRTOS on the officially supported Armv8-M architecture. Amazon Web Services (AWS) released the latest FreeRTOS kernel that includes a preconfigured example project for the Nuvoton NuMaker-PFM-M2351 evaluation board (shown).
At the beginning of 2019, the M2351 Series had achieved Arm PSA (Platform System Architecture) Level 1 Certified and PSA Functional certifications. PSA Certified enables device makers to achieve the security required for their use cases through three progressive levels of security assurance, each requiring increasingly rigorous hardware and software evaluation, which are assigned by analyzing the use case threat vectors.

Secure Wi-Fi MCU Provides IoT Connectivity Solution
Espressif Systems has announced the release of the ESP32-S2 Secure Wi-Fi MCU, a highly integrated, low-power, 2.4 GHz Wi-Fi SoC supporting Wi-Fi HT40 and 43 GPIOs. Based on the Xtensa single-core 32-bit LX7 processor, ESP32-S2 can be clocked at up to 240 MHz.
With state-of-the-art power management and RF performance, I/O capabilities and security features, ESP32-S2 is well suited for a wide variety of IoT or connectivity-based applications, including smart home and wearables. With an integrated 240 MHz Xtensa core, ESP32-S2 is sufficient for building the most demanding connected devices without requiring external MCUs, according to Espressif.
ESP32-S2 supports Espressif's software development framework (ESP-IDF), which is a mature and production-ready platform, already used by millions of devices deployed in the field. Availability of common cloud connectivity agents and common product features shortens the time to market. CONTINUE READING Win a Free CD with a Year's Worth of Circuit Cellar Content!

Infineon Technologies to Acquire Cypress Semiconductor
Infineon Technologies and Cypress Semiconductor have announced that the companies have signed a definitive agreement under which Infineon will acquire Cypress for US $23.85 per share in cash, corresponding to an enterprise value of €9.0 billion.
With the addition of Cypress, Infineon expects to strengthen its focus on structural growth drivers and serve a broader range of applications. According to their joint press statement, this will accelerate Infineon's path of profitable growth of recent years. Cypress has a differentiated portfolio of microcontrollers as well as software and connectivity components that are highly complementary to Infineon's leading power semiconductors, sensors and security solutions. Under the terms of the agreement, Infineon will offer US$23.85 in cash for all outstanding shares of Cypress. This corresponds to a fully diluted enterprise value for Cypress of €9.0 billion.

Dual-Core MCUs Blend High Performance and Enhanced Security
STMicroelectronics has announced new STM32H7 MCUs which it claims are the industry's highest-performing Arm Cortex-M general-purpose MCUs, combining dual-core performance with power-saving features and enhanced cyber protection. The new devices leverage a 480 MHz version of the Cortex- M7, the highest performing member of Arm's Cortex-M family, and add a 240 MHz Cortex-M4 core.
With ST's smart architecture, efficient L1 cache, and adaptive real-time ART Accelerator, the MCUs set new speed records at 1327 DMIPS and 3224 CoreMark executing from embedded flash. ST's Chrom-ART Accelerator provides a boost to graphics performance. To maximize energy efficiency, each core operates in its own power domain and can be turned off individually when not needed.
