It runs at 150 MHz, carries 512 KB of Flash program memory organized as 256K x 16, and has 34K x 16 of RAM on die. This is a DSP-optimized core with a full set of control peripherals: PWM, DMA, POR, WDT, plus CAN, I²C, SPI, UART, McBSP, and an external memory interface. The 16-channel 12-bit ADC is built in. It is meant for motor drives, power conversion, digital power supplies, and automotive subsystems like engine management or transmission control where deterministic loop response matters.
The 150 MHz clock rate on the C28x core enables a single-cycle 32x32 multiply-accumulate. This supports PWM switching frequencies and current-loop bandwidths typical for motor drives.
AEC-Q100 and the automotive BOM
The AEC-Q100 qualification covers high-temperature operating life, temperature cycling, ESD, latch-up, and moisture sensitivity.
Memory and peripherals — what fits
The 34K x 16 RAM covers data buffers, lookup tables, and stack for interrupt-heavy loops. The 88 GPIOs and the full set of serial interfaces (CAN, SPI, I²C, SCI, McBSP) mean this part can serve as the central controller in a multi-node automotive network without external expanders.
