IAR Embedded Workbench Available For Renesas MCUs

IAR Systems has announced that the IAR Embedded Workbench is now available for Renesas's SH-2A and SH2A-FPU microcontroller (MCU) architectures. The IAR Embedded Workbench for SuperH is a set of embedded development tools for applications employing the Renesas SH-2A and SH2A-FPU ranges of devices. The toolset comprises the IAR C/C++ Compiler, an assembler, a linker, a librarian, a text editor, a project manager and the IAR C-Spy Debugger in a single integrated development environment.

The IAR C/C++ Compiler delivers reliable compiled code, according to the company. Recent benchmarks show that the IAR C/C++ Compiler for SuperH generates faster and more compact code than competing compilers. Using a number of real-world applications, the IAR C/C++ Compiler generated 7.9 per cent faster and 14.3 per cent smaller code when compared to Renesas's own compiler.

The compiler's built-in FPU support guarantees that the best floating point instruction performance is reached without the need for any time-consuming assembly coding by hand. For SH-2A devices without an FPU, a floating-point software library is included. The IAR C-Spy Debugger includes support for the Renesas E10A-USB probe for on-chip debugging and allows the emulator's trace system to be utilised.

With a number of features, trace data on instruction level or function call level can be used to resolve difficult problems in addition to fine-tuning the application for improved performance. The IAR C-Spy Debugger also features a built-in instruction set simulator for early development and software testing. Third-party debuggers developed by partners of IAR Systems can also be utilised thanks to the wide variety of output formats generated by the linker.

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.
