The 90 MHz clock rate on the C28x core delivers the DSP-style signal processing throughput needed for real-time current-loop closure and sensorless observer algorithms, while the 12-bit ADC with 16 channels handles multi-phase current sensing without an external multiplexer.
A 1.8 V LDO with ±2% accuracy holds the rail inside the spec across load steps. The 1.71 V minimum is the brown-out threshold — the internal POR and brown-out detect reset the core cleanly if the rail dips below that level.
100-HTQFP with exposed pad — thermal and footprint notes
The package is a 100-HTQFP (14x14 mm) with an exposed thermal pad.
Connectivity and peripherals for automotive control
The 54 general-purpose I/O pins provide enough headroom for a motor-drive design with encoder feedback, hall sensors, and auxiliary relay outputs.
