Starter Kit Speeds Development Of Embedded Tasks

Toshiba Electronics Europe has introduced a starter kit for the development of a range of applications, including industrial control systems, consumer multimedia products and home appliances. The BMSKTOPAS900 starter kit is based on the company's TMPA90xCMXBG range of ARM9 32-bit microcontrollers with built-in human-machine interface (HMI) support. The starter kit provides all of the hardware and software needed to speed up the development of embedded applications where HMI features and high levels of connectivity are required.

For the development of home appliances, Toshiba's TMPA90xCMXBG devices simplify compliance with the IEC60730 (Class B) safety standard through an integrated oscillation frequency detector (OFD) that facilitates the hardware monitoring of the central processing unit (CPU) clock. Based on the low-power 32-bit ARM926EJ-S core operating at up to 200MHz, TMPA90xCMXBG microcontrollers feature integrated graphics capabilities including an LCD controller and an image process accelerator that provides on-chip scaling, filtering and image blending at resolutions of up to 800 x 480.

Built-in functionality includes a 10-bit analogue-to-digital converter (ADC), timers, a melody/alarm generator, a USB host/device and SPI, SD-card, UART, I2C and I2S connectivity. A touch-screen controller and a CMOS image sensor provide further flexibility when implementing HMI designs. Toshiba's new starter kit is based around an evaluation board that combines the host microcontroller with a 3.5in (8.9cm) touch-screen display, memory, SD-card sockets, a joystick control and input and output audio jacks with associated audio DAC. Connectivity is offered in the form of Ethernet, USB and RS232 interfaces as well as a JTAG interface to ease debugging.

The onboard memory comprises 64Mbyte SDRAM, 32Mbyte of NOR Flash and 256Mbyte of NAND Flash. The BMSKTOPAS900 is supplied with a J-Link ARM USB-driven JTAG emulator offering download speeds of up to 720Kbyte/s and a maximum JTAG speed of 12MHz. Further development support is available through third-party tools such as Segger Emwin graphical user interface software, an Embos real-time operating system and development software from Atollic, IAR and Keil. For Linux-based designs, a free-of-charge development environment is available from Bplan.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
