90 MHz C28x core for real-time control loops
The TMS320F28069FPZTR: It integrates a 16-channel 12-bit ADC, PWM timers, and CAN, I²C, SPI, SCI, and UART serial interfaces. Typical applications include industrial motor drives, digital power supplies, and automotive control modules where deterministic interrupt response and PWM resolution matter.
Flash and RAM sizing for control firmware
256 KB of Flash (128K x 16) and 50K x 16 of RAM provide enough space for field-oriented control (FOC) algorithms, sensorless observer code, and communication stacks without external memory. The 90 MHz clock gives a 11.1 ns instruction cycle, which keeps the current-loop update rate above 10 kHz for most motor-pole counts. The 12-bit ADC with 16 channels can sample three-phase currents and DC-link voltage in a single trigger sequence, reducing software overhead.
