What this 90 MHz C28x MCU brings to a motor-drive BOM
The 90 MHz core clocks the control law fast enough for high-pole-count PMSM and induction motors; paired with the 16-channel 12-bit ADC, you can sample all three phase currents plus the DC-link voltage in a single interrupt window. The 128 KB on-chip Flash holds a full sensorless FOC library plus CAN and SPI stacks, leaving room for a bootloader and fault tables.
Rated -40 to 105 °C. The core supply is 1.71 V to 1.995 V.
What the 90 MHz and 128 KB Flash mean for fit
At 90 MHz, the C28x pipeline executes a single-cycle MAC. The 128 KB Flash (64K x 16) is the mid-density option in the Piccolo family.
