100 MHz C28x core — what it buys the control loop
The TMS320F28333PGFA runs a 32-bit C28x single-core at 100 MHz. The 512 KB on-chip Flash and 34K x 16 RAM support control algorithms.
Industrial temperature and package fit
Rated -40°C to 85°C, this part suits factory-floor cabinets with thermal cycling. The 176-LQFP (24 mm x 24 mm) is hand-solderable. The 88 GPIOs break out to three headers.
Peripherals and connectivity for drive control
Peripherals include DMA, POR, PWM, and WDT — the PWM module is key for generating complementary switching patterns with dead-band insertion. Connectivity covers CANbus, EBI/EMI, I²C, McBSP, SCI, SPI, and UART/USART. The CAN interface is typically wired to a drive-to-drive link or a motion-bus controller; the SCI and SPI ports handle resolver-to-digital converter reads and encoder data capture. The 16-channel 12-bit ADC samples three-phase currents and a DC-link voltage in one conversion sequence.
