Take motor control designs to the next level with new, highly
integrated C2000™ 32-bit Piccolo™ F2805x microcontrollers
HOUSTON, Nov. 26, 2012 /PRNewswire/ -- Taking the
complexity out of motor control designs, Texas Instruments
Incorporated (TI) (NASDAQ: TXN) introduces its latest motor
control solution – new highly integrated C2000™ Piccolo™ F2805x
microcontrollers, motor control software, application-specific
development tools and extensive support. These Piccolo
microcontrollers are optimized for a variety of three-phase
inverter motor control applications to enhance power efficiency and
control performance of electric pumps, fans, traction drives,
textile machines and more.
The new Piccolo F2805x microcontrollers pack a number of analog
components on chip to increase system efficiency and decrease the
number of discrete parts. Piccolo F2805x microcontrollers offer the
intelligence and performance of the TMS320C28x™ digital signal
processing (DSP) core with a C-programmable Control Law Accelerator
(CLA) co-processor on-chip. The CLA is a 32-bit floating-point math
accelerator, designed to work independently of the CPU core to
offload time-sensitive control algorithms or DSP processing,
freeing the CPU to handle motion profiles, system management,
communications and safety checking, resulting in up to a 5x
increase in performance for closed loop applications.
Features and benefits of the Piccolo F2805x
microcontrollers:
- C28x CPU running at 60 MHz with C-programmable, 32-bit
floating-point CLA co-processor running at 60 MHz ease
programming, improve flexibility and enable direct access to
on-chip peripherals for parallel execution of algorithms and
control loops. The CLA enables faster system response, higher KHz
control loops and improved triggering and fault detection.
- Embedded memory for more storage, including up to 128 KB
Flash and up to 20 KB SRAM. Boot ROM and dual 128-bit security key
on protected zones for both Flash and ROM ensure code security for
entire device or mixed-source software development.
- On-chip communication interfaces, such as an SPI module,
I2C bus, CAN 2.0 and 3 SCI/UART modules improve connectivity for
real-time communications.
- Integrated analog to improve system efficiency and reduce
bill of materials cost (BOM):
- 12-bit analog-to-digital converter (ADC) up to 2.3 MSPS for
synchronous motor-phase readings – dual sample and hold.
- 14 enhanced pulse-width-modulation (PWM) channels with fault
management, providing motor control for multiple motors, as well as
power conversion.
- 7 windowed analog comparators with 10-bit digital-to-analog
converters (DACs) provide individual current feedback for each
motor phase, integrated fault protection and accurate, on-time
feedback.
- Dual, zero-pin oscillators increase system robustness by
integrating the clock source on-chip and providing a second, backup
oscillator for smooth recovery from clock failure conditions.
- Voltage regulator decreases system complexity and costs,
enabling a single voltage supply rail to power the
microcontroller.
- Up to 4 programmable gain amplifiers (PGAs) act as variable
resistors to adjust incoming feedback waveforms prior to ADC
conversion, eliminating the costs and reducing board area.
- 32-bit enhanced input capture module (eCAP) and enhanced
quadrature encoder pulse (eQEP) module for sensored motor control
to accurately detect and capture position and speed of rotating
motion systems.
Tools, software, training and support make motor control
development a breeze
Designers can begin development easily with TI's motor control
development kits with free open source motor control software
libraries and examples. These libraries and example projects are
available for both the C28x and CLA cores of the Piccolo F2805x
microcontrollers and include functions covering nearly all
essential motor control mathematical functions, as well as
device-specific peripheral configurations. Designed with simplicity
in mind, the motor control libraries are completely modular and
ideal for all stages of development, enabling designers to connect
together functional software code blocks, similar to connecting
blocks of a block diagram. After connecting the software blocks of
the motor control libraries, designers can simply tune their
parameters, compile the code and flash into the Piccolo F2805x
microcontroller.
C2000 Piccolo-based modular development tools enable
experimentation with various C2000 microcontrollers to fit price
performance and peripheral feature-set requirements. These tools
include: C2000 LaunchPad, controlCARD, controlSTICK and C2000
experimenter kits. All of these tools include TI's Code Composer
Studio v5 integrated development environment and C2000
controlSUITE™ software, providing easy-to-use open
source demonstration GUIs, software examples and documentation for
motor control development. Motor control training is
available online, and 24/7 support can be found on TI's E2E
Community.
Pricing and availability
Piccolo F2805x microcontrollers are available for order now
