productroundup TI Sitara MCUs based on Mainline Linux kernel Basing its kit around, Texas Instruments says, a high-quality, stable Linux platform, the Mainline Linux kernel support enables ease of migration by providing consistent access to new devices and the latest features. TI's Sitara Linux SDK provides a robust, stable Mainline Linux kernel for developers using TI's Sitara processors. To ensure high quality, TI collaborates with the Kernel.org community for code reviews with stringent acceptance criteria. TI also continuously stress tests the Linux kernel across various customer use cases and applications to guarantee stability. TI's Sitara Linux SDK 7.0, supporting the latest Mainline Linux kernel, is available to download today, along with a range of supporting information. The SDK is currently compatible with Sitara AM335x processors. Future TI devices with Linux software support will include TI's Sitara AM4x and AM5x processors as well as TI's KeyStone multicore system-onchips based on ARM cores. Complete article, here Extended temperature range for ARM MCUs For extreme industrial environments, NXP Semiconductors has added LPC microcontrollers rated for temperatures up to 105C. The LPC11E6x family is designed for harsh operating conditions common in many industrial, lighting, and industrial automation applications. The LPC11E6x family is available in three memory and package variations, including up to 256 kB Flash, 36 kB RAM and 4 kB EE PROM. Power efficiency is achieved through an ARM Cortex-M0+ core and NXP’s power profiles that allow various power saving options depending on the application demands. High-precision analogue features include a 2 Msamples/sec, 12-channel, 12-bit ADC, and connectivity is provided through I2C and SPI interfaces, USARTs, and up to 80 GPIOs. Also new to the LPC1100 Series, the LPC11E6x's two on-chip SCTimer/PWMs support advanced timing features. This block can be configured as multiple PWMs, a PWM with dead-time control, a PWM with reset capability, and many other functions. ARM-based Kinetis MCUs for motor control Freescale Semiconductor’s lead families of the new Kinetis V series, based on ARM Cortex-M cores, are optimised for motor control and digital power conversion applications. Freescale accompanies them with the Kinetis Motor Suite tool. The KV4x family is the flagship of the existing V series, targeting digital power conversion designs, as well as PMSM and ACIM applications requiring high dynamic control. KV4x MCUs incorporate a 150 MHz ARM Cortex-M4 processor with floating-point unit executing from up to 256 kB of Flash memory via a 128-bit wide interface that minimises CPU wait states. With up to 30 timer channels – twelve provided by the flexible eFlexPWM – KV4x family devices provide multiple three-phase motor drive capabilities supporting dead time insertion, complementary pairing of PWMs, half cycle reload and fault detection. For sensorless motor control speed/position detection, two 12-bit ADCs support sample rates of up to 1.9 Msamples/ sec and can be triggered by any module connected to the MCU’s internal peripheral crossbar, including timers, analogue comparators or GPIO. For switched mode power supply applications, an eFlexPWM module provides 300 picosecond resolution, while the ADCs sample at 4.1 Msamples/sec. This improves realtime control, ensuring that critical timing windows for data gathering and system updates are met. Complete article, here Highly-integrated WiFi in 14 x 16 mm Econais has what it claims is the smallest, most integrated Wi-Fi (SiP) module; the integrated hardware/software and low standby power requirements simplify smart home, M2M and IoT device design and development. EC19W01 is an 802.11b/g/n Wi-Fi System In Package (SiP) module that has low power drain and features fully integrated MCU, Wi-Fi, cloud connectivity, flash and antenna that is fully certified FCC, EC, IC, and TELEC. The module incorporates Wi-Fi 802.11b/g/n standards and is fully certified with FCC, EC, IC, and (soon) TELEC. Features include AirPlay, Wi-Fi Direct, ProbMe configuration, full TCP/IP stack, HTTPS/SSL, DHCP Client/Server, WPS, legacy Wi-Fi Client and SoftAP modes with WPA/WPA2 support, Serial to Wi-Fi, and Cloud Service Support; the EC19W01 is 14x16x2.8mm in size.
