What this Piccolo MCU brings to a real-time control loop
The TMS320F28067PZPS is a 32-bit C28x Piccolo microcontroller from Texas Instruments, built for closed-loop control in motor drives, digital power supplies, and industrial inverters. Its 90 MHz core, 256 KB Flash, and 50K x 16 RAM give enough headroom for a three-phase FOC algorithm plus a Modbus stack without external memory.
90 MHz — what it buys the loop closure
Running at 90 MHz, the C28x core executes a single-cycle MAC on 32-bit data. The 256 KB Flash stores roughly 64k instructions.
