Frequently asked questions
Are there second-source or cross-compatible options?
The TMS320F28069MPZT is a TI C2000 part with no ledger-listed cross-reference or second-source MPN. Sourcing through franchised distributors is the traceable path; independent channel stock at this lifecycle stage carries authenticity risk. Full traceability documentation — COO, date code, CofC — is required for BOM compliance and audit.
For a motor-control design, do I need an external ADC or is the 16x12b on-chip ADC sufficient?
The 16-channel 12-bit ADC is the on-chip feedback path for most inverter and servo drive designs. It handles current sensing for FOC and voltage feedback for digital PWM without requiring an external SAR ADC, provided layout practice keeps PWM noise out of the analog section and the 12-bit ENOB meets your current loop precision requirement. If your design demands more than 16 sense channels or finer current resolution, an external converter becomes necessary.
