TI’s latest Piccolo MCUs feature new Control Law Accelerator (CLA) floating point unit

Texas Instruments announced TMS320F2803x Piccolo
microcontrollers (MCUs) featuring the Control Law Accelerator (CLA).
Unique to TI's F2803x Piccolo MCUs, the CLA is a 32-bit floating-point
math accelerator that operates independently of the C28x core, allowing
for direct access to on-chip peripherals and parallel execution of
algorithms. The CLA has it's own register set, memory bus structure and
processing unit. It's interrupt driven architecture can perform the
operations of reading the result of the analog to digital conversion
and then adjusting
the output of the ePWM–all without involving the main C28x processor
  Three particular applications that this MCU is geared towards
are variable speed motor control, digital power control, and LED
lighting control.

The F2803x MCUs are an extension to TI's Piccolo series and are 100
percent code-compatible across the TMS320C2000 MCU platform, making
switching within the family much easier. Currently there are more than
30 Piccolo
configurations available.

F2803x Piccolo MCU key features and benefits

  • 60 MHz C28x core and 60 MHz CLA provide performance
    execute complex control algorithms with a single Piccolo MCU
  • Flexible
    control peripherals such as high-resolution PWMs, high-speed 12-bit ADC
    and 32-bit captures reduce sample-to-output delay 
  • 32-bit Control Law Accelerator
    • Direct access to on-chip control peripherals for
      parallel execution
      of algorithms
    • Fully programmable IEEE floating-point unit
      reduces scaling and
      saturation burden
    • Operates independently of the C28x core for software
  • Wide range of F2803x configurations provides
    to scale designs: 64KB to 128KB flash, 64-pin/80-pin packages, 1050C
    and 1250C

Pricing and availability

The F2803x series will start at $3.50 at 1KU
pricing. The TMX320F28035 is the superset of the F2803x series and is
sampling today. The F28035 controlCARD (TMDXCNCD28035) and F28035
Experimenter's Kit (TMDXDOCK28035) are also immediately available for
order entry and are priced at $59 and $89, respectively. These tools
build on TI's controlCARD concept, jumpstarting development through
removable daughtercards with general and application specific target
