90 MHz C28x core — real-time loop headroom
The TMS320F28065PZPS: The C28x core runs at 90 MHz, setting the PWM update rate and ADC sampling window for motor-drive or digital-power loops.
On-chip peripherals include a 16-channel 12-bit ADC, six PWM modules with dead-band generation, and a watchdog timer. Communication interfaces cover CANbus, I²C, SPI, SCI, and UART/USART — enough for a CANopen node with a local sensor bus. The 54 GPIOs can be mapped to most of these interfaces, but the pin-multiplexing table in the datasheet must be checked early in layout to avoid routing conflicts.
This MCU carries an EOL hot lifecycle stage, meaning TI has announced end-of-life and a last-time-buy window is open or closing.
