The TMS320F28068MPNT: Its 90 MHz core clock and 256 KB of on-chip Flash provide enough headroom and code space for a field-oriented control loop with a commutation update every 50 µs. The 50K x 16 RAM holds the state vectors and lookup tables without external memory.
The 40 GPIOs include the PWM outputs, six-channel ADC inputs (12-bit, 12-channel), and the CAN, I²C, SPI, SCI, and UART interfaces.
Pin-compatible alternatives within the same C2000 Piccolo family include parts with different Flash or RAM densities, such as the TMS320F28067 or TMS320F28069. The exact pinout and peripheral set vary by density; check the TI cross-reference guide for your required memory and feature set.
Level shifters are required when interfacing with 3.3 V peripherals.
