Microcontrollers turn to motor control
Microchip has expanded its product range for the electronic motor control market with a new PIC microcontroller, the PIC16F716, and three new MPLAB-compatible development tools.
Microchip has expanded its product range for the electronic motor control market with a new PIC microcontroller, the PIC16F716, and three new MPLAB-compatible development tools With over seven billion motors manufactured every year, and only about 20% of them controlled electronically, Microchip's system solutions for a broad range of motor types allow companies to cost-effectively add electronic control to their motor-driven products

Easy interfacing to faster microcontrollers
Microchip has added two new devices to its PIC16C92X family of 8bit one-time-programmable microcontrollers with integrated liquid-crystal display controller.
These manufacturers are under increasing pressure, due to environmental regulations, to increase the energy efficiency of motor-driven products, and by adding variable speed control using Microchip's PIC and dsPIC products, designers can achieve typical energy savings of 14-30% in a number of motor control applications.
One of many microcontroller devices from Microchip targeted at motor control, the new 18-pin PIC16F716 features an enhanced capture/compare/PWM module, which supports bidirectional brushed DC motor control.
The module offers four PWM outputs, programmable dead-band control and auto shutdown for enhanced safety.

Micropower op amp shrinks into SOT-23 package
Microchip's new 2.5 V micropower operational amplifier is available in a tiny SOT-23 package.
The device also features programmable brownout reset and four channels of 8bit analogue to digital conversion.
Other devices well-suited to motor control applications include the PIC18Fxx31 family, ideal for low cost, advanced brushless DC and AC induction motor control; the 16bit dsPIC30F DSC motor control and power conversion family, ideal for higher performance applications such as sensorless control; and the PIC16F7x7 family, ideal for open-loop control of induction motors.
Microchip also offers a complete line of analogue and interface products, including mosfet drivers, fan managers, temperature sensors and operational amplifiers.
Microchip has created a Windows based software environment for the development of electronic motor control applications.
The Motor Control Graphical User Interface (MC-GUI) is available to download at no cost from the Microchip website.
Compatible with MC-GUI, the new PICDEM MC development board supports brushless DC and AC induction motor control designs using the PIC18Fxx31 family.
This PIC microcontroller family features three advanced motor control modules, including a three-phase PWM module with fault detection, and a quadrature encoder interface.
The PICDEM MC provides electrical isolation from the power circuitry, allowing users to fully utilise the MPLAB ICD2 in-circuit debugger and MPLAB ICE2000 in-circuit emulator for programming, debugging and emulation.
In addition, an isolated serial connection to the MC-GUI software enables users to modify their application parameters "on the fly".
The board also includes hex, assembler and C source files to provide a complete reference design.
The dsPIC30F motor control development system is a complete set of modular development tools and software libraries to support motor control designs using the seven dsPIC30F devices that are targeted at motor control and power conversion applications (the dsPIC30F2010, 3010, 3011, 4011, 4012, 5015 and 6010).
These products are ideal for motor control applications that require higher precision, higher-speed operation or sensorless control, and this development system provides simple prototyping and validation of brushless DC, permanent magnet, AC induction and switched reluctance motor applications.
The dsPICDEM MC1 motor control development board forms the core of the system, and features a plug-in dsPIC30F6010 device module preprogrammed with commutation routines for brushed and brushless DC motors, and a variable voltage/frequency routine for AC induction motors.
Sensorless brushless DC motor software is also available.
The board is also fully compatible with the MPLAB ICD2 in-circuit debugger and MPLAB ICE4000 in-circuit emulator.
The PICDEM MC development board (DM183011) is available now for $299.
The dsPIC motor control development system is also available now.
The dsPICDEM MC1 motor control development board (DM300020) costs $300 and combines with either the dsPICDEM MC1H 3-phase high voltage power module (DM300021) at $800, or the dsPICDEM MC1L three-phase low voltage power module (DM300022) at $700.
