Microchip Technology Introduces a New Core in the dsPIC® Digital Signal Controller Family to Enhance Precision and Execution of Real-Time Control
30 Julio 2024 - 4:59AM
As embedded systems become more complex and the need for enhanced
performance increases, Microchip Technology
(Nasdaq:
MCHP) has launched its
dsPIC33A Core family of
Digital Signal Controllers (DSCs). The ability for
engineers to create sophisticated, computationally intensive
embedded control algorithms is crucial for achieving superior
operational efficiency in motor control, power supply, charging and
sensing systems. Built around a 32-bit Central Processing Unit
(CPU) architecture with a 200 MHz operating speed, the dsPIC33A
family’s advanced core includes a Double-Precision Floating-Point
Unit (DP FPU) and DSP instructions for numerically intensive tasks
in many closed-loop control algorithms. The dsPIC33A architecture
offers high-performance and precise real-time control coupled with
a comprehensive development tool ecosystem to streamline and
accelerate the design process.
"The dsPIC33A DSCs are a game-changer for developers because
they are designed to offer the precision, efficiency and advanced
features needed to push the boundaries of embedded system
performance," said Joe Thomsen, vice president of Microchip’s
digital signal controller business unit. "With its ability to
enable complex designs, address safety and security requirements,
integrate advanced functionality and accelerate time-to-market, the
dsPIC33A family positions our clients to secure a larger market
share with innovative, competitive designs."
The dsPIC33A DSCs are enhanced with improved math and data
processing, higher code efficiency, faster context switching and
reduced latency. This lower latency allows for a faster response
time to transient and safety-critical events. New and upgraded
peripherals—such as high-resolution PWMs specifically engineered
for motor control and digital power conversion—are designed to
support progressive technology development in various markets
including automotive, industrial, consumer, E-Mobility, data center
and sustainable solutions segments. The dsPIC33A family features
integrated analog peripherals, including 12-bit ADCs capable of
conversion rates up to 40 Msps, high-speed comparators and
operational amplifiers. These analog peripherals, in conjunction
with Core Independent Peripherals (CIPs), allow for sophisticated
sensing and high-performance control. In addition, the CIPs enable
interaction among the peripherals without the need for CPU
involvement, enhancing the efficiency of a single controller to
manage multiple tasks. The result is more robust real-time control
while reserving the CPU bandwidth for software stacks, functional
safety diagnostics and security functions.
The dsPIC33A device families are outfitted with Flash security
capabilities, including an Immutable Root of Trust, secure
debugging and restricted memory access. The DSCs’ Instruction Set
Architecture (ISA) enables the adoption of software code generated
by model-based designs to simplify code generation. The combined
features make dsPIC33A DSCs well suited for applications that
require efficient motor control for fans, pumps and compressors;
they also manage digital power conversion for applications like AI
servers and on-board chargers in electric vehicles and enable
sensor interfacing for industrial and automotive applications.
The first family of dsPIC33AK128MC1xx DSCs includes 128 KB Flash
and an extensive peripheral set, offered in various packages,
including SSOP, VQFN and TQFP options ranging from 28 to 64 pins,
with package dimensions as small as at 4 × 4 mm. Future dsPIC33A
families with additional memory, peripherals and larger pin counts
will complete the portfolio. Visit Microchip’s Digital
Signal Controllers web page to learn more about the
company’s full line of DSC devices.
Development Tools The dsPIC33A family is
supported by the MPLAB® XC-DSC Compiler, MPLAB Code Configurator
(MCC) and the dsPIC33A Curiosity Development Board (EV74H48A). The
dsPIC33A Curiosity Development Board supports feature expansion by
providing mikroBUS™ and Xplained Pro interfaces that enable
connection to Built-in Self Text Xplained Pro (BIST XPRO) extension
kits, sensors and various Click boards™. Separate dual In-line
modules are available to support development for motor control,
digital power conversion and general-purpose embedded applications.
