Build Larger, More Robust Applications with Microchip’s Expanded Dual- and Single-core dsPIC® Digital Signal Controller (D...

System developers designing high-end embedded control applications
need flexible options to provide scalability as projects increase
in complexity. To meet these needs, Microchip Technology Inc.
(Nasdaq: MCHP) today announced new dual- and
single-core dsPIC33C Digital Signal Controllers (DSCs) with more
options to meet changing application requirements across memory,
temperature and functional safety.
Microchip’s new dsPIC33CH512MP508 dual-core DSC
enables support for applications with larger program memory
requirements. The dsPIC33CK64MP105 single-core DSC
adds a cost-optimized version for applications that require smaller
memory and footprint. Developers can easily scale across product
lines using the new devices, which are pin-to-pin compatible within
the dsPIC33CH and dsPIC33CK families.
The dsPIC33CH512MP508 (MP5) family expands the recently
introduced dsPIC33CH with Flash memory growing from 128 KB to 512
KB and triples the program RAM from 24 KB to 72 KB. This enables
support for larger applications with multiple software stacks or
larger program memory, such as automotive and wireless charging
applications. More memory is needed to accommodate AUTOSAR
software, MCAL drivers and CAN FD peripherals in automotive
applications. Implementing wireless charging in automotive
applications requires additional software stacks for the Qi
protocol and Near-Field Communication (NFC), driving the need for
even more program memory. Using Live Update capability for
real-time firmware updates is essential for high-availability
systems but also doubles the overall memory requirement. In the
dual-core devices, one core can function as a master while the
other is designed as a slave. The slave core is useful for
executing dedicated, time-critical control code while the master
core is busy running the user interface, system monitoring and
communications functions. For example, having two cores facilitates
partitioning of the software stacks for parallel execution of the
Qi protocol and other functions such as NFC to optimize performance
in automotive wireless charging applications.
The dsPIC33CK64MP105 (MP1) family extends the recently
introduced dsPIC33CK family with a cost-optimized version for
smaller memory and footprint applications, offering up to 64 KB
Flash memory and 28- to 48- pin packages. Package sizes are
available as small as 4 mm x 4 mm. This compact device offers the
ideal combination of features for automotive sensors, motor
control, high-density DC-DC applications or stand-alone Qi
transmitters. Both single- and dual-core dsPIC33C devices enable
fast deterministic performance for time-critical control
applications, providing expanded context selected registers to
reduce interrupt latency and bringing faster instruction execution
of math-intensive algorithms.
“With 76 dsPIC33C single- and dual-core devices in the family,
the common tools, common peripherals and footprint compatibility
make it easier for customers to scale as their memory, I/O,
performance or budget needs change,” said Joe Thomsen, vice
president of Microchip’s MCU16 business unit. “In addition, the
dual-core options enable easier software integration for separate
software development teams to focus on control algorithms versus
communications and housekeeping code.”
All devices in the dsPIC33C family include a fully featured set
of functional safety hardware to ease ASIL-B and ASIL-C
certifications in safety-critical applications. Functional safety
features include multiple redundant clock sources, Fail Safe Clock
Monitor (FSCM), IO ports read-back, Flash Error Correction Code
(ECC), RAM Built-In Self-Test (BIST), write protection, analog
peripheral redundancies and more. A robust set of CAN-FD
peripherals, along with the new support for 150°C operation, make
these devices ideally suited for use in extreme operating
conditions such as under-the-hood automotive applications.
Development SupportThe dsPIC33C family is
supported by Microchip’s MPLAB® development ecosystem including
Microchip’s free MPLAB X Integrated Development Environment (IDE),
MPLAB Code Configurator, MPLAB XC16 C Compiler tool chain and MPLAB
in-circuit debugger/programmer tools. Microchip’s motorBench™
Development Suite version 2.0, now supporting high voltage motors
up to 600V, is also available to help customers tune motors using
the Field Oriented Control (FOC) algorithm.
A variety of development boards and Plug-in Modules (PIMs) are
available for the entire family of devices. Development tools for
the new devices include the dsPIC33CH Curiosity Board (DM330028-2),
the dsPIC33CH512MP508 PIM for general-purpose designs (MA330046),
the dsPIC33CH512MP508 PIM for motor control (MA330045), the
dsPIC33CK64MP105 PIM for general purpose designs (MA330047), the
dsPIC33CK64MP105 PIM for external op amp motor control (MA330050-1)
and the dsPIC33CK64MP105 for internal op amp motor control
(MA330050-2).
Pricing and AvailabilityThe dsPIC33CH512MP5
devices are available now in 48-/64-/80-pin TQFP, 64-pin QFN and
48-pin uQFN packages. The dsPIC33CK64MP1 devices are available now
in 28-pin SSOP, 28-/36-/48-pin uQFN and 48-pin TQFP packages.
Pricing for the dsPIC33C devices start at $1.34 each in high
volume. The dsPIC33CH Curiosity development board is available now
for $39.99 each.The dsPIC33C PIM development boards mentioned above
are available now for $25.00 each.
