MCUs Enable LCD Implementation into Designs

PIC16LF190x MCUs enable the implementation of LCD into cost-sensitive designs, such as security tokens, smart cards, medical devices, home appliances, key fobs and other segmented LCD applications. Featuring Extreme Low Power (XLP) technology, with sleep currents down to 20nA and a typical active current of 35mA/MHz, the MCUs extend battery life, while maintaining accurate timing with a RTC and driving a segmented LCD. Incorporating Microchip's Enhanced Mid-range architecture, the PIC16LF190x range provides features and performance without incurring the cost of unused peripherals.

The optimised feature set integrates up to 14kB of Flash programme memory, up to 512 bytes of RAM and up to 14 10-bit Analogue-to-Digital Converter (ADC) channels, as well as serial communication and the capability to drive up to 116 LCD segments. The MCUs also feature XLP technology for extended battery life and capabilities such as an integrated temperature indicator to provide crystal-accuracy compensation, as well as support for low-power RTC and low-voltage detect using the internal ADC and voltage reference.

The PIC16LF1902, PIC16LF1903 and PIC16LF1906 MCUs are available in 28-pin SPDIP, SOIC, SSOP and 4 x 4mm UQFN and die packages, while the PIC16LF1904 and PIC16LF1907 MCUs feature 40-pin PDIP, 5 x 5mm UQFN and die packages, as well as a 44-pin TQFP.

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.
