FAQ

What is the maximum ADC sampling rate supported by the TMS320F28063UPNT?

The TMS320F28063UPNT supports a maximum ADC sampling rate of 3.46 MSPS with its 12-bit dual sample-and-hold architecture. This enables synchronized acquisition across up to 16 input channels, critical for real-time current reconstruction in three-phase motor control. The 289-ns conversion time ensures minimal latency in feedback loops, directly supporting high-bandwidth control algorithms executed on the C28x core or CLA. TMS320F28063UPNT maintains this performance across its full –40°C to 105°C operating range.

Does the TMS320F28063UPNT include a floating-point unit (FPU)?

Yes, the TMS320F28063UPNT integrates a native single-precision floating-point unit (FPU) alongside its C28x 32-bit CPU. This allows direct execution of IEEE 754-compliant floating-point arithmetic without software emulation, significantly accelerating mathematical operations used in motor control (e.g., Park/Clarke transforms, PID tuning). The FPU is fully accessible to both the main CPU and CLA, enabling consistent numerical precision across parallel control tasks. TMS320F28063UPNT leverages this for seamless C/C++ development in TI's C2000™ ecosystem.

Is USB functionality available on the TMS320F28063UPNT?

No, USB functionality is not available on the TMS320F28063UPNT. According to the official Device Comparison table (SPRS698J), USB 2.0 is only implemented on TMS320F2806xU, TMS320F2806xM, and TMS320F2806xF variants. The TMS320F28063UPNT lacks the USB0DP/USB0DM pins entirely in its 80-pin LQFP package. For host/device connectivity, designers must use SCI/UART, SPI, I²C, or eCAN peripherals. TMS320F28063UPNT retains full compatibility with TI's standard debug interface via JTAG (TCK/TDI/TDO/TRST).

What is the role of the CLA in the TMS320F28063UPNT?

The Control Law Accelerator (CLA) in the TMS320F28063UPNT is a 32-bit floating-point co-processor that executes control algorithms independently of the main C28x CPU. It accesses shared RAM and peripherals-including ePWM, ADC, and GPIO-enabling concurrent execution of inner current loops while the CPU handles outer position/speed loops and communication. This eliminates scheduling conflicts and guarantees sub-microsecond interrupt latency. TMS320F28063UPNT uses the CLA to achieve deterministic real-time performance essential for servo drives and high-frequency digital power converters.

How many ePWM modules does the TMS320F28063UPNT support?

The TMS320F28063UPNT supports eight Enhanced Pulse-Width Modulator (ePWM) modules, providing a total of 16 PWM output channels. Eight of these channels feature High-Resolution PWM (HRPWM) capability for sub-nanosecond timing control-critical for SiC/GaN gate driving and soft-switching topologies. Each ePWM module includes independent 16-bit timers, dead-band generation, and trip-zone inputs linked to analog comparators. TMS320F28063UPNT maps all ePWM signals to multiplexed GPIO pins, with pin assignments confirmed in the 80-pin PN package diagram (Figure 6-1).
