Microchip débuts new PICs and dsPICs

17 August 2011 DSP, Micros & Memory

Microchip announced a new series of 16-bit PIC microcontrollers (MCUs) and dsPIC digital signal controllers (DSCs) that bring advanced control to cost-sensitive general purpose and motor control designs.

The new devices enable sensorless motor control designs with support for a wide range of motor control algorithms, plus an on-chip charge time measurement unit (CTMU), 10-bit analog-to-digital converter (ADC) and mTouch capacitive touch sensing to enable intelligent sensor applications. The devices are supported by three new plug-in modules and a single-board motor control starter kit that includes capacitive-touch sliders and an onboard BLDC motor. This makes it possible for designers to create high-performance appliances such as washing machines, medical products such as infusion pumps, and industrial AC induction motors.

The new dsPIC33FJ16 ‘GP’, dsPIC33FJ16 and PIC24FJ16 ‘MC’ devices have specialised features and peripherals optimised for general purpose and motor control applications. In addition to their on-chip CTMU and ADC peripherals, the general-purpose dsPIC33FJ16 ‘GP’ DSCs include a real-time clock/calendar and up to 21 general-purpose output pins, making them ideal for driving intelligent sensors.

The dsPIC33FJ16 and PIC24FJ16 ‘MC’ devices include a 6-channel pulse-width modulation peripheral with synchronised outputs for three-phase operation, enabling support for a wide range of motor-control algorithms and applications. These range from simple sensored motors to advanced sinusoidal field-oriented control, brushless DC, permanent magnet and synchronous AC induction motors.
