The TMS320F28065PFPS is a 32-bit C28x core clocked at 90 MHz. It carries 128 KB of program Flash and 50K x 16 of RAM, with 12-bit ADC across 12 channels, CAN, I²C, SPI, and UART connectivity.
This part is flagged end-of-life hot (EOL hot). Texas Instruments has not published a formal last-time-buy window on this specific variant.
The TMS320F2806x family (e.g., TMS320F28069) is the natural migration path within the Piccolo series. Pin compatibility and software migration guides are documented in TI application notes. No exact alternate MPN is listed in this evidence, but the C2000 design ecosystem supports drop-in evaluation.
The core runs at 90 MHz. That is the C28x clock rate for the arithmetic logic unit and control-law accelerator, not the system bus — the bus operates at the same frequency for zero-wait-state Flash access.
