12/20/2004 - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced that it has begun volume production of two 16-bit dsPIC® Digital Signal Controllers (DSCs) that offer designers performance speeds of 20 and 30 Million Instructions Per Second (MIPS), self-programming capabilities via Flash memory and industrial and extended temperature ranges. The dsPIC30F4011 and dsPIC30F4012 motor control and power conversion family add 48 Kbytes of Flash program memory and CAN capability, and are ideal for power conversion applications and for motor control applications that require higher precision, higher-speed operation or sensorless control.
The use of sensorless motor control is growing because it eliminates the cost and reliability implications of mechanical sensors. However, sensorless motor control requires increased computing horsepower at cost-effective price points. In addition, engineers are moving toward the combination of motors and control in a single unit, placing extreme size constraints on electronic control components. The dsPIC30F4011 and dsPIC30F4012 provide the cost-effective performance needed for sensorless motor control, with form factors as small as 8x8 mm in QFN packages. In addition, these DSCs have a motor control PWM and a quadrature encoder interface that is ideal for electronic control of brushed permanent magnet, switched reluctance, brushless DC (BLDC) and AC induction motors (ACIM).
Microchip’s dsPIC DSC combines the high-performance of a 16-bit Flash microcontroller with the computation and throughput capabilities of a digital signal processor (DSP). The dsPIC DSCs have the “heart” of a 16-bit microcontroller with robust peripherals and fast interrupt handling capability, and the “mind” of a DSP that manages high-computation activities, creating the optimum single-chip solution for embedded system designs. This allows designers to integrate functions and save board space.
“These two new dsPIC30F devices mark a total of 10 dsPIC DSCs that have been released to volume production this year,” said Sumit Mitra, vice president of Microchip’s Digital Signal Controller Division. “Engineers worldwide are designing in the 16-bit dsPIC DSC because it seamlessly integrates DSP capabilities and microcontroller functionality in a single core, providing the best of both worlds.”
Microchip’s Enhanced Flash self-programming capability features a remote upgrade to the Flash program memory allowing code revisions in end-users’ applications. These features provide flexibility, reduced development time, increased manufacturing efficiency and faster time to market.
The dsPIC30F4011 and dsPIC30F4012 are able to operate at five volts, which is valuable for noise immunity and minimizing voltage translation logic. Additional key features include:
