- 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.
