What the 100 MHz C28x core buys you in a control loop
The TMS320F2806NMFA runs a single C28x core at 100 MHz — that is the clock rate that decides whether your digital power loop or motor current regulator fits inside the switching period. With a single-cycle 32×32 multiply-accumulate, the C28x can execute a PID or a Park/Clarke transform in a handful of cycles, leaving headroom for commutation sequencing and fault detection. If your loop time budget is under 10 µs, this part keeps you out of assembly.
32 KB Flash — plan for a fixed-function firmware image
Program memory is 32 KB of Flash — enough for a single control algorithm with a modest parameter table, but not a multi-boot or field-upgradable firmware stack.
16-channel 12-bit ADC — analog front-end without an external mux
The on-chip ADC provides 16 channels at 12-bit resolution. In a three-phase motor drive, that covers three phase currents, a DC-link voltage, and a temperature sensor with channels to spare.
Package and supply — 100-LFBGA, 1.8 V core
The 100-ball LFBGA (10×10 mm) is a fine-pitch BGA. Core supply is 1.71 V to 1.89 V; the -40°C to 85°C temperature range covers industrial enclosures and outdoor telecom cabinets.
