Reader O f f er Trinamic’s stepper motor package gets you started This month, Trinamic Motion Control is offering you to win one of four TMCM-1043 development kits for its highly integrated, NEMA 17-compatible TMCM- 1043 stepDancer stepper motor module. Offering designers an easy-to-use PC-based GUI that allows one-click modification of motor drive current, micro-stepping and other key parameters, the intuitive kits are custom designed and developed for direct mounting on a NEMA 17 motor. Pre-programmed and pre-configured with all operating parameters to support standard 1.5A (peak) motors, the TMCM- 1043 board uses Trinamic´s single-axis TMC2660 stepper motor driver IC, which integrates a motor pre-driver and power MOSFETs. Controlled by industry standard step/direction pulses, the TMCM-1043 module automatically performs all motor coil current calculations, while driving an external NEMA 17 motor with the industry’s lowest RDS(on) MOSFETs.

The A5100-A is suitable for applications including wearable devices, cameras and automotive trackers. It is the first release in Maestro’s new line of GNSS receivers, and achieves high levels of accuracy with quad-constellation support, up to 30% faster Time-To-First-Fix (TTFF), and up to 20% lower power consumption using CSRs TricklePower and Push-to-Fix (PtF) modes. The module reduces development risks by integrating a number of features including, TCXO, SAW filter, RTC, antenna control mechanism, and flash memory for future-proof upgrades, as well as, offering a drop-in replacement capability for Maestros previous SiRFstar4 generation modules. The castellated edge form factor also enables simpler manufacturing and reduces assembly cost. Supporting all currently deployed GNSS, the A5100-A acquires and tracks all visible GPS, GLONASS, QZSS, and SBAS satellites. Concurrent GNSS performance enables the A5100-A to choose the best satellites from different constellations and deliver optimal location information. By combining low power consumption with high sensitivity, high jamming immunity and concurrent GNSS operation, and with its drop in upgrade path to the A2200-A, the A5100-A creates a fast and convenient route to the latest GNSS offering in the marketplace. Maestro Wireless Solutions www.maestro-wireless.com Toshiba targets smart meters with new ARM Cortex-M4F MCU An addition to Toshiba Electronics Europe’s TX04 series of ARM Cortex®-M4F core-based microcontrollers, the TMPM- 411F20XBG MCU facilitates electric power calculation and communication in smart meters, as well as sensing and communications in other measurement devices. A typical smart meter comprises separate controllers for electric power calculation, data communication, and output display. By integrating multiple functionalities, the TMPM411F20XBG achieves independent control of the electric power calculation and communication control in a single chip, reducing the circuit board area within the smart meter. The TMPM411F20XBG implements tamper detection and failure detection with very low power consumption, and also incorporates key security functions suitable for secure network communication. These include Advanced Encryption Standard (AES), Secure Hash Algorithm (SHA) and Entropy Source Generator (ESG). Its large on-chip Flash memory allows for robust code and data storage as required for extensive service lifetime. Delivered in a 14x14mm VFGBA193 package, the TMPM411F20XBG operates at 2.7 to 3.6V, with a maximum operating frequency of 80MHz. It has an internal memory of 2048 Kbytes Flash and 290 Kbytes total SRAM, 34-channel direct memory access (DMA), 9-channel 12-bit analog-to-digital converter (ADC). Toshiba Electronics Europe www.toshiba-components.com High directivity 0302 thin film couplers for WiFi bands AVX’ high directivity 0302 thin film couplers for WiFi bands, including the latest, tight tolerance 0302 component are now available through distribution. The WiFi band couplers are based on multilayer integrated thin film (ITF) technology, which provides the miniature components with high frequency performance across the WiFi spectrum (2,400-5,905 MHz) and rugged construction for reliable automatic assembly. Available in 0302, 0402, and 0603 packages, each of which exhibit identical electrical performance, AVX’s WiFi band couplers also feature land grid array (LGA) packaging technology, the benefits of which include: inherently low profile, self alignment during reflow, excellent solderability, low parasitics, and effective heat dissipation. AVX’s high directivity couplers for WiFi bands are rated for an operating temperature range spanning -40 up to +85C; and are 100% tested for electrical parameters. Part numbers are CP0302A5425ENTR and, for tight tolerance, CP0302P5425ENTR. AVX ww.avx.com 46 Electronic Engineering Times Europe September 2014 www.electronics-eetimes.com
