150 MHz C28x core — real-time control loop headroom
The TMS320F28334PGFA is a 32-bit C28x Delfino microcontroller from Texas Instruments. It runs at 150 MHz.
176-LQFP — hand-solderable, no BGA rework
This part comes in a 176-pin LQFP with a 24x24 mm body. No BGA, no underfill, no X-ray inspection. The 88 GPIOs fan out to the four sides, so a 4- or 6-layer board with a solid ground plane is the practical minimum for signal integrity.
Industrial temperature, not automotive
No last-time-buy risk for ongoing designs.
Peripherals and connectivity for system integration
On-chip peripherals include DMA, POR, PWM, and WDT — the PWM module is the key one for three-phase inverter control, with dead-band generation and trip-zone inputs. Connectivity covers CANbus, EBI/EMI, I²C, McBSP, SCI, SPI, and UART/USART, so it can talk to an external ADC, an encoder interface, or a host controller on the same board.
