Microcontroller Range Features Up To 96KB Of RAM

Microchip has announced the eight-member PIC24FJ256DA microcontroller range for consumer, home appliance, industrial and portable medical applications. The range integrates three graphics acceleration units and a display controller, along with up to 96KB of RAM. This reduces system costs and allows the practical addition of advanced graphics displays for a wide range of embedded applications by eliminating the need for external RAM and a display controller. Additional savings are achieved through the integrated peripherals for USB and capacitive touch sensing.

Microchip's PIC24FJ256DA range allows designers to migrate beyond fixed-function, segmented LCDs to STN, TFT and OLED displays with up to VGA resolution. This range also features 24 channels of on-chip Mtouch capacitive touch sensing, which enable a large number of buttons, sliders and keys. The integrated Full-Speed USB embedded host, device and on-the-go module allows end users to easily upgrade software, log data and customise settings. Example applications for the PIC24FJ256DA range include: consumer - thermostats, cordless phones, remote controls, gaming accessories; home appliance - coffee makers, ovens, refrigerators, washing machines; industrial - points of sale, remote terminals; and portable medical devices - glucometers, blood-pressure monitors, portable ECGs.

To enable quick time to market, Microchip's Graphics Display Design Centre provides a host of resources for application designers. This platform comprises Microchip's free and performance-optimised Graphics Library, which comes with the full source code, supports multiple fonts and languages and includes a host of pre-made graphics objects. The free Graphics Display Designer software provides first-time users with a visual wizard for designing user interfaces. The Graphics Library also comes with pre-configured interfaces for capacitive touch pads and sliders, plus resistive touch screens. Microchip has also created the PIC24FJ256DA210 development kit to enable out-of-the-box graphics development.

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.
