C28x core at 60 MHz — real-time control loop headroom
The TMS320F28051PNT is a Texas Instruments C28x Piccolo 32-bit single-core MCU built for real-time control applications — motor drives, digital power supplies, and industrial inverters. Its 60 MHz C28x core delivers the MAC throughput needed for sensorless field-oriented control (FOC) loops and digital filter stages without an external DSP. The 64 KB (32K x 16) on-chip Flash and 8K x 16 RAM hold a moderate control firmware image; expect to fit a single FOC algorithm with commutation tables and a CAN stack, but not a multi-axis motion controller. The 16-channel 12-bit ADC samples three-phase currents and a DC-link voltage in one conversion sequence — no external mux or sample-and-hold required for most drive topologies.
Core logic runs from a 1.71 V to 1.995 V supply.
Peripherals and connectivity — what the on-chip blocks cover
CANbus is the primary fieldbus for industrial drives; the I²C, SCI, SPI, and UART interfaces handle sensor bridges, local HMI, and debug.
