| MCU Enables Dynamic 3D Graphics
in Automotive Instrument Displays Cypress Semiconductor has announced a new series in its Traveo automotive microcontroller family with more memory to support a hybrid instrument cluster with 3D graphics and up to 6 traditional gauges, as well as a head-up display. The highly integrated, single-chip devices in the S6J32xEK series include an advanced 3D and 2.5D graphics engine and provide scalability with Cypress' low-pin-count HyperBus memory interface. The series continues the company's expansion of its automotive portfolio with differentiated system performance via its MCUs, wireless radios, capacitive-touch solutions, memories, and PMICs. The Traveo S6J32xEK series integrates up to 4 MB of high-density embedded flash, 512 kB RAM, 2 MB of Video RAM, an ARM Cortex-R5 core at 240 MHz performance, a low-voltage differential signaling (LVDS) video output, a low-voltage transistor-transistor logic (LVTTL) video output, and a 6x stepper motor control. This combination enables the devices to serve as single-chip solutions to drive two displays. The devices have up to two 12-pin HyperBus memory interfaces that dramatically improve read and write performance of graphical data and other data or code. MCU Delivers Enhanced Security for IoT Devices Renesas Electronics has announced the expansion of its RX65N/RX651 Group microcontroller lineup that addresses advanced security needs for connected devices operating in industrial automation, building automation, and smart metering systems. The expanded lineup features MCUs with integrated Trusted Secure IP and enhanced, trusted flash functionality and human-machine interface (HMI) for industrial and network control systems. The expansion of devices operating at the edge of the Industrial Internet of Things (IIoT) has increased system manufacturers' need for secure network connectivity and reliability, including secure on-the-go firmware updates. The expanded RX65N/RX651 devices support these evolving security and reprogrammability needs, offering integrated Trusted Secure IP, enhanced flash protection, and other technology advancements to create a secure and stable integrated solution, as proven by the device's Cryptographic Algorithm Validation Program (CAVP) certification. |

STMicroelectronics supports ARM's new Platform Security Architecture (PSA) in ST's STM32H7 high-performing microcontrollers. People and organizations are increasingly dependent on connected electronic devices to manage time, monitor health, handle social interactions, consume or deliver services, maximize productivity, and many other activities. Preventing unauthorized interactions with these devices is essential to protecting identity, personal information, physical assets, and intellectual property. As device manufacturers must always innovate to beat new and inventive hacking exploits, PSA helps them implement state-of-the-art security cost-effectively in small, resource-constrained devices.  ST's STM32H7 MCU devices integrate hardware-based security features including a True Random-Number Generator (TRNG) and advanced cryptographic processor, that will simplify protecting embedded applications and global IoT systems against attacks like eavesdropping, spoofing, or man-in-the-middle interception. In addition, secure firmware loading facilities help OEMs ensure their products can be programmed safely and securely, even off-site at a contract manufacturer or programming house.

Texas Instruments (TI) has unveiled its lowest-cost, ultra-low-power MSP430 microcontrollers for sensing applications. Developers can now implement simple sensing solutions through a variety of integrated mixed-signal features in this family of MSP430 value line sensing MCUs, available for as low as $0.25 in high volumes. Additions to the family include two new, entry-level devices and a new TI LaunchPa development kit for quick and easy evaluation.  Developers now have the flexibility to customize 25 common system-level functions including timers, input/output expanders, system reset controllers, electrically erasable programmable read-only memory (EEPROM), and more using a library of code examples. A common core architecture, a tools and software ecosystem, and extensive documentation including migration guides make it easy for developers to choose the right MSP430 value line sensing MCU for each of their designs. Designers can scale from the 0.5-kB MSP430FR2000 MCU to the rest of the MSP430 sensing and measurement MCU portfolio for applications that need up to 256 kB of memory, higher performance, or more peripherals.
Microchip has expanded its PIC18 product line to include a new line of 8-bit microcontrollers that combine a Controller Area Network (CAN) bus with an extensive array of Core Independent Peripherals (CIPs). The CIPs increase system capabilities while making it easier for designers to create CAN-based applications without the complexity of added software. A key advantage of using a K83 MCU in CAN-based systems is that the CIPs provide deterministic response to real time events, shorten design time, and can be easily configured through the MPLAB Code Configurator (MCC) tool. The new family is well suited for applications using CAN in the medical, industrial, and automotive markets, such as motorized surgical tables, asset tracking, ultrasound machines, automated conveyors, and automotive accessories.  The PIC18 K83 devices contain 15 time-saving CIPs including Cyclic Redundancy Check (CRC) with memory scan for ensuring the integrity of non-volatile memory, Direct Memory Access (DMA) enabling data transfers between memory and peripherals without CPU involvement, Windowed Watchdog Timer (WWDT) for triggering system resets, 12-bit Analog-to-Digital Converter with Computation (ADC2) for automating analog signal analysis for real-time system response, and Complementary Waveform Generator (CWG) enabling high-efficiency synchronous switching for motor control..
