C2000™ Family

The TI C2000™ MCU family has been delivering leading, real-time, control performance in digital power and motor control applications for more than two decades. These MCUs integrate flash memory, analog-to-digital converter (ADC) modules for parallel measurements in time-critical applications, high resolution pulse width modulation (HRPWM), digital signal processor (DSP), and more. The applications of the C2000™ family range from standalone inverters up to full powertrain integration, including traction inverters, onboard chargers (OBC), high voltage DC-DC converters, heating ventilation and air conditioning (HVAC).

C2000™ MCUs include a TI proprietary 64-bit C29 CPU for real-time processing along with C2000™ control technology, which is a proven, flexible architecture for advanced control. The measured performance of the execution time of the C2000™ MCUs is outstanding among the competition, see Figure 4-1. Specifically, the C2000™ MCUs included in the F29H85x family of devices offers the following competitive advantages:

  • Functional safety compliant up to ASIL D
  • 4MB of flash
  • A hardware security module (HSM) and configurable logic block (CLB), which supports:
    • AUTOSAR
    • MCAL
    • Third-party basic software modules (BSW)

TI's C2000™ MCUs include the following features to help accelerate control algorithms for traction inverters:

  • A state machine-based 32-bit floating-point control law accelerator capable of independent code execution from the main DSP core field-oriented control
  • Support for 32-bit floating point operations or 64-bit floating point in this family
  • A trigonometric math unit (TMU) that provides intrinsic instructions to support common trigonometric math functions common in transforms and torque loop calculations.
  • Reduced cycle counts for both Viterbi and cyclic redundancy check operations found in complex math equations
