FAQ

What is the maximum operating frequency of the C28x CPUs in the F28384DPTPS?

The F28384DPTPS integrates two TMS320C28x 32-bit DSP cores, each operating at 200 MHz. This frequency applies to both CPU1 and CPU2, enabling deterministic execution of floating-point and fixed-point control algorithms with sub-microsecond interrupt response times critical for high-switching-frequency power converters.

Does the F28384DPTPS support EtherCAT communication?

Yes, the F28384DPTPS includes a dedicated EtherCAT Slave Controller (ESC) within its Connectivity Manager (CM) subsystem. The ESC supports full EtherCAT protocol handling-including distributed clocks, process data exchange, and mailbox communication-without burdening the C28x real-time control cores.

What analog-to-digital converter performance does the F28384DPTPS provide?

The F28384DPTPS features four independent ADCs, each configurable for 16-bit resolution at 1.1 MSPS or 12-bit resolution at 3.5 MSPS. Each ADC includes a dedicated sample-and-hold, hardware post-processing, and supports up to 24 single-ended or 12 differential inputs with simultaneous sampling capability.

How is functional safety implemented in the F28384DPTPS?

The F28384DPTPS is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. It includes hardware safety mechanisms such as lockstep-capable watchdog timers, dual-clock comparators, memory ECC/parity protection, BGCRC, ERAD, and HWBIST-enabling systematic development of safety-critical motor control and power conversion systems.

What package and thermal characteristics apply to the F28384DPTPS?

The F28384DPTPS uses the 176-pin HLQFP (PTP) package with PowerPAD™ thermal enhancement. Its 24 mm × 24 mm body includes an exposed thermal pad for low-thermal-resistance PCB mounting, supporting continuous operation at junction temperatures up to 125°C under industrial conditions.
