Microchip Technology Announces PIC(R) Microcontrollers with Internal Shunt Regulator.PIC16F616/HV616 Family Provides Specialized Peripherals for Low-Cost Motor/Fan Control CHANDLER, Ariz. -- Microchip Technology Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on : MCHP MCHP Maryland Children's Health Program MCHP Microchip Technologies (stock symbol) MCHP Micro-sized Combined Heat and Power (American Honda Motor Co. & Climate Energy, LLC) MCHP Maine Community Heritage Project ), a leading provider of microcontroller and analog semiconductors, today announced the first general-purpose, Flash PIC([R]) microcontrollers with several peripherals for more cost-effective control of fans or small motors. The 14-pin PIC16F616/610 and the 8-pin PIC12F615/609 microcontrollers can substantially reduce system component counts and costs through the integration of specialized peripherals, such as a full-bridge Pulse-Width Modulator (PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a ) with deadband control, a Timer1 Gate for pulse width measurement, a comparator for hall-effect sensor interfaces, and an A/D converter for temperature and various monitoring functions. In the case of the PIC16HV616/610 and PIC12HV615/609 variants, the addition of an internal shunt regulator allows the PIC microcontroller to run from higher voltage rails without the addition of voltage regulators. Engineers designing small-motor control systems are always looking for ways to eliminate components and reduce board size and cost, while achieving higher levels of functionality and flexibility. For example, in cooling fans, the PIC16F616/610 and PIC12F615/609 Flash microcontrollers provide greater functionality than discrete fan-control components, such as linear speed control, improved dynamic response and the ability to customize the design with firmware changes rather than expensive hardware redesigns. At the same time, board space and cost is reduced with features such as comparator hysterisis, to allow direct interfacing to a hall-effect element without additional signal-conditioning circuitry. Many high-voltage-rail applications, such as motor control and power supplies, require components to step down the input voltage for various control devices. However, these new PIC microcontrollersCoavailable with an integrated shunt regulator option (designated with "HV" in the part number), allow engineers to design systems without having to add a regulator, reducing costs and board space even further. Additionally, motor and power applications often require intermediate voltages for power drivers and other power components. The PIC16F616/HV616 family addresses these requirements with a built-in S/R S/R Subroutine S/R Storage and Retrieval S/R Sustained Release S/R Send & Receive S/R Sunroof S/R Suspend/Resume S/R Shipping and Receiving S/R Safety/Relief S/R Screen Role (basketball) S/R Shipping Request latch to design a switch-mode power supply for these intermediate voltages. "Engineers who used to rely solely on analog and discrete semiconductors for their designs have discovered the flexibility and lower system cost benefits of using a PIC microcontroller," said Steve Drehobl, vice president of Microchip's Security, Microcontroller and Technology Development Division. "Microchip continues to lead the way in providing these engineers with new PIC microcontrollers that enable them to design compact, programmable and cost-effective applications." Specific application examples include: home appliances (such as blenders, toasters, smoke alarms and thermostat controls), cooling-fan control and other motor control, power tools, system control and monitoring, battery chargers, automated door sensors, speedometers, and power supplies. Key features for the PIC16F616/610 and PIC12F615/609 microcontrollers, and their HV variants, include: * Enhanced Full-Bridge PWM peripheral with capture and compare functionality, dead-band control and emergency shutdown * Internal Shunt Regulator that allows High-Voltage Vdd support from 2V to a user-defined max (HV variants, only) * Up to two Comparators with selectable Hysterisis, internal voltage-reference options, and S/R latch mode for switch mode power conversion * Up to eight 10-bit Analog-to-Digital Conversion channels * High Stability, Precision 4/8 MHz Internal Oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air * Up to 3.5 Kbytes (2K Words) of Flash Program Memory; 128 bytes RAM * Brownout A lowering of AC power voltage for some period of time. Brownouts can be very harmful to electronic equipment if sustained for long periods. Brownouts can cause flickering or a dimming on screen, and the computer may experience intermittent problems as a result. See blackout.
