C28x Piccolo for real-time control — what the 90 MHz core and memory mean
The TMS320F28063UPNT: Its 90 MHz C28x core delivers the compute headroom for nested PID loops and space-vector modulation without stalling the control law. The 128 KB (64K x 16) Flash and 34K x 16 RAM provide enough code space and data buffer for a typical three-phase motor control stack plus a CANopen or Modbus stack over the integrated CANbus and UART interfaces. The 12-bit ADC with 12 channels maps directly to phase current sensing on a shunt or Hall-effect transducer; paired with the PWM module, the part can trigger a synchronized conversion at the PWM carrier peak, eliminating the jitter that plagues software-triggered sampling in a 16 kHz current loop.
Obsolete — read the PCN before you commit a BOM line
That means TI has stopped manufacturing this exact package and speed grade; no further last-time-buy windows are open. For a production BOM, the only supply channel is independent distribution — surplus or new-old-stock (NOS) lots that were pulled before the EOL date. Date-code provenance matters here: stock that surfaced years after the official last-time-buy deserves a careful counterfeit screen, especially on a part with a 12x12 mm 80-LQFP that can be re-marked.
80-LQFP footprint and supply rails — board-level fit
The part comes in an 80-LQFP package (12x12 mm) with 40 usable I/O.
