FAQ

What is the maximum operating frequency and instruction cycle time of the TMS320F28062FPZT?

The TMS320F28062FPZT operates at a maximum CPU frequency of 90 MHz, delivering an instruction cycle time of 11.11 ns. This timing is guaranteed across the full –40°C to 105°C industrial temperature range and enables sub-microsecond execution of critical control loops. The TMS320F28062FPZT achieves this performance using a zero-wait-state memory architecture for on-chip flash and RAM.

Does the TMS320F28062FPZT include a floating-point unit (FPU) and programmable control law accelerator (CLA)?

Yes, the TMS320F28062FPZT integrates both a single-precision IEEE 754 floating-point unit (FPU) and a programmable control law accelerator (CLA). The CLA is a fully independent 32-bit floating-point processor that executes control code in parallel with the main C28x CPU - enabling simultaneous current regulation (on CLA) and communication stack handling (on CPU) without timing conflict. This dual-core architecture is confirmed in the SPRS698J datasheet Section 1.

What ADC specifications does the TMS320F28062FPZT support?

The TMS320F28062FPZT features a 12-bit analog-to-digital converter with dual sample-and-hold capability, achieving up to 3.46 million samples per second (MSPS) and supporting up to 16 input channels. Conversion time is fixed at 289 ns, and the ADC accepts a 0–3.3-V input range with ratio-metric reference support via VREFHI/VREFLO pins. These parameters are explicitly listed in Table 5-1 of the SPRS698J datasheet.

How many ePWM channels does the TMS320F28062FPZT provide, and which support high-resolution mode?

The TMS320F28062FPZT provides 14 ePWM output channels across seven modules, with 8 channels supporting high-resolution PWM (HRPWM) mode. HRPWM enables <150-ps duty-cycle resolution - critical for precise dead-time control in SiC and GaN power stages. This configuration is documented in the Device Comparison table (Table 5-1) of the SPRS698J datasheet under "ePWM channels" and "High-resolution ePWM Channels" rows.

What package type and thermal requirements apply to the TMS320F28062FPZT?

The TMS320F28062FPZT uses a 100-pin HTQFP package with PowerPAD™ (PZP), measuring 14.0 mm × 14.0 mm. Its exposed thermal pad must be soldered to the PCB ground plane using ≥9 thermal vias (0.3-mm diameter) to meet junction-to-board thermal resistance requirements. The PowerPAD is not electrically connected to internal VSS and serves only thermal conduction - failure to connect it properly risks thermal shutdown during sustained 90-MHz operation.
