Core Architecture: The C28x 32 bit CPU

The C2000 controller uses a central 32 bit CPU core, called C28x, coupled with a highly optimized peripheral and interrupt management bus. As a cross between a general microcontroller and a digital signal processor, the C28x core brings the code density and execution speed of a DSP with the ease of use and accessibility of a microcontroller. Features include:

• Efficient C engine with hardware that allows a C compiler to generate compact code, resulting in industry-leading code density
• Single cycle read-modify-write instructions, single cycle 32 bit multiply.
• Fast interrupt service time (down to 9 cycles) with automatic zero-cycle context save.
• 96 dedicated interrupt vectors that require no software decision making
• 32 bit floating-point unit on select controllers
• On select Piccolo devices, an independent Control Law Accelerator (CLA) processes floating-point control loops to free the CPU for other purposes.
• Three 32 bit general purpose CPU timers brings unprecedented accuracy and flexibility to any applications.
• Code Security Module prevents reverse engineering and protects valuable intellectual property
• VCU increases complex math performance by up to 7.5X and enables intergration of advanced Power Line Communication protocols

Powerful Peripherals

C2000 controllers include advanced integrated peripheral modules that bring more value to systems. Peripherals include:

• Enhanced PWM modules offer high resolution (down to 65ps) duty cycle, period, and phase control. Additionally, fully programmable trip zone detection and dead-time generators offer complete system protection from faults and surges.
• Up to 16 analog input channels with a 12-bit ADC sampling up to 12.5 MSPS – the industry´s leading embedded ADC. Designed for speed and flexibility, C2000´s ADCs feature autosequencing to minimize CPU interruption.
• Enhanced Capture units based on 32 bit timers allow high accuracy sensing and more flexibility.
• Quadrature Encoder Pulse (QEP) modules on select controllers decodes position signals with hardware.
• SPI, UART/SCI, CAN, I2C, and LIN communication modules connect C2000 controllers with the rest of the system.
