New PIC32 MCUs Optimized For Motor Control Applications

The latest family of PIC32 microcontrollers (MCUs) is now available from Microchip Technology, The PIC32MK family features four highly integrated MCUs for precision dual Motor Control applications (PIC32MK MC) and eight MCUs packed with serial communication modules for General Purpose (PIC32MK GP) applications. All MC and GP devices feature a 120 MHz 32-bit core that supports Digital Signal Processor (DSP) instructions. Additionally, to ease control algorithm development, a double-precision floating point unit is integrated into the MCU core enabling customers to utilize floating-point based modeling and simulation tools for code development.

 

To increase efficiency and decrease the number of discrete devices needed in motor control applications, the high-performance PIC32MK MC devices combine 32-bit processing with advanced analog peripherals such as a quad 10 MHz op amp, high-speed comparators and motor-control optimized Pulse Width Modulation (PWM) modules. The devices also have Analog-to-Digital Converter (ADC) modules capable of total throughput of 25.45 Mega-Samples Per Second (MSPS) in 12-bit mode or 33.79 MSPS in 8-bit mode, enabling higher precision in motor control applications. The devices come with up to 1 MB Live Update Flash, 4 KB of EEPROM and 256 KB SRAM.

The devices have up to four independent CAN 2.0 ports as well as six Universal Asynchronous Receiver/Transmitter (UART) modules, Local Interconnect Network (LIN) 1.2 and six Serial Peripheral Interface (SPI) or Inter-IC Sound (I2S) modules. Additionally, two complete full-speed USB modules are included on select devices enabling simultaneous USB host and USB device to be active at the same time.  A single MCU can be used to communicate to multiple bus protocols for reduced design complexity and cost, making PIC32MK devices ideal for dual-USB applications such as digital audio or CAN-based implementations in the automotive and industrial markets.

 

Development Support

 

The family is supported by the MPLAB Harmony Integrated Software Framework, MPLAB X Integrated Development Environment (IDE), MPLAB XC32 Compiler for PIC32, MPLAB ICD 3 In-Circuit Debugger and MPLAB REAL ICE™ In-Circuit Emulation system.

 

The PIC32MK devices have peripheral block support for MathWorks® MATLAB® and Simulink® as well as open-source-based Scilab for customers interested in numerical computation computing environments for engineering and scientific applications.

 

Pricing and Availability

 

Devices in the PIC32MK family are offered with up to 1 MB Flash and 256 KB SRAM in 64- and 100-pin TQFP and QFN packaging options. All devices are available today in volume production starting at $4.50 in 10K quantities.
