FAQ

What is the maximum operating temperature range for the TMS320F28069PZPA?

The TMS320F28069PZPA is rated for operation from –40°C to 105°C (industrial temperature grade). This range is validated per TI's characterization and supports deployment in demanding environments such as motor drive cabinets and outdoor solar inverters without forced cooling.

Does the TMS320F28069PZPA support hardware-based security features?

Yes, the TMS320F28069PZPA includes a Code Security Module (CSM) with 128-bit password protection, secure OTP ROM, and flash/SARAM locking. These features prevent unauthorized access to firmware and enable secure boot verification - critical for protecting proprietary motor control algorithms.

Can the TMS320F28069PZPA execute control algorithms independently using the CLA?

Yes, the TMS320F28069PZPA integrates a dedicated 32-bit floating-point CLA that runs code concurrently with the main C28x CPU. It accesses shared RAM and peripherals directly, enabling real-time execution of PID loops, Clarke/Park transforms, or observer calculations without CPU intervention.

What ADC configuration options does the TMS320F28069PZPA provide for motor current sensing?

The TMS320F28069PZPA features a 12-bit dual sample-and-hold ADC with 16 input channels and 3.46-MSPS throughput. It supports simultaneous sampling across up to 4 channel pairs, enabling accurate three-shunt or dual-shunt current reconstruction synchronized to ePWM triggers.

Is the TMS320F28069PZPA pin-compatible with other devices in the F2806x family?

Yes, the TMS320F28069PZPA in the 100-pin PZP package shares identical pinout and footprint with TMS320F28069M, TMS320F28069F, and TMS320F28068M/F variants - enabling hardware reuse across designs targeting different feature sets (e.g., InstaSPIN, USB, or VCU).
