120 MHz C28x core — real-time control throughput
The TMS320F28075PTPQR is a 32-bit C28x fixed-point MCU from Texas Instruments, clocked at 120 MHz. That core speed, paired with the 512 KB Flash and 50K x 16 RAM, handles multiple control loops.
Automotive grade and temperature range
AEC-Q100 qualified and rated for -40 to 125 °C, this part is built for under-hood electronics — engine management, transmission controllers, and electric-drive inverters. The same temperature range also suits industrial motor drives and outdoor telecom power supplies where ambient heat soaks the enclosure. The 1.14 V to 1.26 V core supply is tight; the board design needs a clean rail, typically from a dedicated LDO or a switching regulator with low ripple.
Lifecycle and sourcing reality
The product status is listed as Active, but the EOL hot flag in the record signals that a phase-out notice is imminent or already issued. For a BOM line that depends on this exact order code, the window for last-time buys may be closing.
Peripherals and connectivity
On-chip peripherals include DMA, POR, PWM, and WDT — the PWM module is the key for three-phase inverter control with dead-band insertion. Connectivity covers CANbus, EBI/EMI, I²C, McBSP, SCI, SPI, UART/USART, and USB, so the MCU can talk to a CAN transceiver for vehicle networks, an external memory via EBI, or a host PC over USB for firmware updates. The 97 GPIOs leave room for local sensor interfaces and relay drivers without an external expander.
Analog conversion resources
Seventeen 12-bit ADC channels and one 12-bit DAC cover the analog front-end for current sensing, voltage feedback, and analog set-point outputs. The ADC samples simultaneously on multiple channels — useful for three-phase current measurement where you need a snapshot of all phases at the same switching instant.
