New16-bit PIC MCUs and dsPIC DSCs for
low-cost, sensorless motor-control apps
Microchip Technology has announced a new series of 16-bit
PIC microcontrollers (MCUs) and dsPIC Digital Signal Controllers
(DSCs) for designing low-cost, sensorless motor-control
designs with support for a range of motor-control algorithms,
and include an on-chip Charge Time Measurement Unit (CTMU),
and10-bit Analog-to-Digital Converter (ADC), to enable intelligent
sensor applications, and mTouch capacitive touch sensing.
The devices are supported by three new Plug-In Modules (PIMs)
and a single-board motor-control starter kit that includes
cap-touch sliders and an onboard BLDC motor for applications
in the appliance (e.g. washing machines), medical (e.g.
infusion pumps) and industrial (e.g. AC-induction motors)
markets, among others.
The general-purpose dsPIC33FJ16 "GP" devices
include a Real-Time Clock/Calendar and up to 21 general-purpose
output pins. The dsPIC33FJ16 and PIC24FJ16 "MC"
devices include a 6-channel Pulse-Width Modulation (PWM)
peripheral with synchronised outputs for 3-phase operation.
"Customers are always looking for ways to incorporate
more features and functionality into their designs without
increasing costs," said Sumit Mitra, vice president
of Microchip's High-Performance Microcontroller Division.
"The dsPIC33FJ16 DSCs and PIC24FJ16 MCUs meet these
needs, with the 'MC' versions enabling customers to enjoy
the benefits of advanced motor control, such as higher efficiency,
quieter operation, smoother torque and higher reliability."
Packaging and availability:
The dsPIC33FJ16GP101 DSC is available in 18-pin PDIP and
SOIC packages, as well as a 20-pin SSOP packages. The dsPIC33FJ16GP102
and dsPIC33FJ16MC102 DSCs, and PIC24FJ16MC102 MCU, are available
in 28-pin QFN-S, SDIP, SOIC, and SSOP packages, as well
as a 36-pin VLAP package. The dsPIC33FJ16MC101 DSC and PIC24FJ16MC101
MCU are available in 20-pin PDIP, SOIC and SSOP packages.
