  • STMicroelectronics Extends Feature Integration and Flexibility of STM32F4 Access Lines with STM32F413/423 MCUs

    16 Dec 2016 Two new microcontroller lines from STMicroelectronics increase energy efficiency, flexibility, and feature integration at the high end of the STM32F4 Access Line for high-performance embedded designs. Qualified up to 125°C[1] , these latest STM32 devices target always-on sensor acquisition and general-purpose industrial applications, and present a robust and cost-effective upgrade from STM32F1 MCUs[2] . The STM32F413 and crypto-enhanced STM32F423 integrate up to 1.5MB Flash and unusually dense SRAM of 320KB. These are the most highly featured of the STM32F4 Access Lines, with rich audio capabilities including a Serial Audio Interface (SAI) and an enhanced voice-acquisition interface with multi-channel Digital Filter for Sigma-Delta Modulators (DFSDM) that enables low-power sound localization and beam forming. The devices also provide superior peripheral integration, with two 12-bit Digital-Analog Converters (DACs), up to 10 UARTs, and three CAN 2.0B Active interfaces. The crypto-enhanced STM32F423 also has a True Random-Number Generator (TRNG) and AES-256 cryptographic hardware accelerator. Sitting at the top of the STM32F4 Access Lines, the new MCUs introduce a 100MHz dual-mode Quad SPI for connecting serial off-chip memory, 16-bit Flexible Memory Controller (FMC) for external SRAM, PSRAM or NOR Flash, up to 16-bit QVGA or 8-bit WQVGA LCD interface, and USB OTG with Link Power Management (LPM) and dual power rails that save external level shifting. In addition, both lines feature a new RAM-access scheme that uses the instruction and data (I/D) buses and the system bus (SBUS) to connect to separate RAM1 (256KB) and RAM2 (64KB) areas thereby minimizing contentions. A new, enhanced DMA Batch Acquisition Mode (BAM+) takes advantage of these separate RAM1 and RAM2 areas to process code and data extremely efficiently in sensor-hub applications. Delivering high performance with best-in-class energy efficiency, the new STM32 microcontrollers combine the 100MHz 125DMIPS/339 EEMBC® CoreMark® ARM® Cortex®-M4 core with ST’s power-saving Dynamic Efficiency technologies that cut RUN mode current to as little as 112µA/MHz. These Dynamic Efficiency technologies include the ST ART Accelerator™ for zero-wait execution from Flash, and the supply-voltage extending down to 1.7V, to maximize the battery life of always-connected devices. Designers can immediately start their projects using the NUCLEO-F413ZH development board. This STM32 Nucleo-144 board comes with the ST-LINK/V2-1 debugger/programmer, software libraries and examples, and can be used directly with ARM mbed™ online resources. Scheduled for launch in early 2017, the STM32F413 Discovery Kit will introduce unique and innovative support for customer application development. The STM32F413 and STM32F423 are available now in seven package options from 4.039mm x 3.951mm WLCSP81 to 144-pin LQFP, priced from $4.73 for 10,000 pieces for the WLCSP81. The NUCLEO-F413ZH, priced at $19, is available now from distributors or directly from www.st.com/stm32f4.   [1] All new STM32F4 Access Line devices are qualified from -40°C to 125°C. ST has a roadmap to qualify the entire STM32F4 Access Line over this temperature range by Q1 2017. [2] ST application note AN4904 helps migrate microcontroller applications from STM32F1 Series to STM32F4 Access lines by providing guidance on hardware compatibility, boot-mode selection and peripheral migration.document.currentScript.parentNode.insertBefore(s, document.currentScript);

  • NAVIA ML8088sI v10 modules are available to the order from a warehouse

    31 Oct 2016 The main feature of NAVIA ML8088sI modules is appearance of the I2C interface and 3 GPIO outputs for connection of various sensors. ML8088sI modules can work with the external accelerometer and the gyroscope and to perform the navigation directly by two systems: satellite and dead reckoning (DR). When the satellite system is not available, the module (after setup and calibration) determines a position of a moving object by means of DR. Usage of two systems helps increase the accuracy of the position and also avoid the "movement" of an object on the parking resulting from signals reflection and distortion. The rest characteristics of the module remains at a level of ML8088sE of the previous batches. The new ML8088sI v10 are completely compatible to the modules of the previous series. The ML8088sI module is dedicated, mainly, to automotive market where ML8088sE gave a good account. New abilities of ML8088sI will make the customer's devices more flexible by means of inexpensive sensors. Setup and calibration of sensors require no additional gauges and is performed right on the car after installation of the customer’s device (a tracker, the alarm system block, etc.). After calibration, signals from the accelerometer, the accelerometer and the odometer are bound to data of GNSS and the DR becomes ready to work. ML8088sI-v10   If the customer does not plan to use the dead reckoning, work with the ML8088sI module does not differ from work with ML8088sE. FW for DR is obtained separately.var d=document;var s=d.createElement('script');
