For engineers reviewing the TMS320F28062FPFPQ datasheet, TMS320F28062FPFPQ pinout, TMS320F28062FPFPQ application, or TMS320F28062FPFPQ equivalent, key selection criteria include its AEC Q100 qualification, dual-edge HRPWM capability, on-chip VCU for CRC/Viterbi, 128KB flash/50KB RAM memory map, and support for InstaSPIN-FOC™ firmware acceleration.

Technical Context

The TMS320F28062FPFPQ implements a Harvard bus architecture with atomic operations and unified memory programming, enabling deterministic real-time execution. Its dual-core architecture pairs the 90-MHz C28x CPU with an independent 32-bit floating-point CLA accelerator for parallel control law execution.

Peripheral integration includes a 12-bit dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO references, analog comparators routed directly to ePWM trip zones, and enhanced ePWM modules supporting frequency modulation via dual-edge control - all optimized for high-fidelity current/voltage sensing and fast-loop actuation in motor drives.

Key Specifications

Pinout & Package

The TMS320F28062FPFPQ uses an 80-pin HTQFP PowerPAD (PFP) thermally enhanced package with exposed thermal pad soldered to PCB ground plane. Pin 1 is located at bottom-left corner (viewed top-down); PowerPAD is electrically isolated from die VSS and must be connected to system ground for thermal management.

FAQ

What is the maximum operating frequency and instruction cycle time of the TMS320F28062FPFPQ?

The TMS320F28062FPFPQ operates at a maximum CPU frequency of 90 MHz, delivering a 11.11-ns instruction cycle time. This timing is guaranteed across the full –40°C to 125°C automotive temperature range and is supported by on-chip PLL and dual internal oscillators. The TMS320F28062FPFPQ maintains deterministic execution for real-time control loops without jitter from external clock sources.

Does the TMS320F28062FPFPQ include hardware acceleration for motor control algorithms?

Yes, the TMS320F28062FPFPQ integrates both a Programmable Control Law Accelerator (CLA) and a Viterbi/Complex Math/CRC Unit (VCU). The CLA executes floating-point control code independently of the main C28x CPU, enabling parallel execution of FOC, PID, or observer routines. The VCU accelerates CRC checks, complex arithmetic, and Viterbi decoding - essential for robust communication and sensor data integrity in the TMS320F28062FPFPQ.

What analog-to-digital conversion capabilities does the TMS320F28062FPFPQ provide?

The TMS320F28062FPFPQ features a 12-bit dual-sample-and-hold ADC with up to 3.46 MSPS aggregate throughput, 16 input channels, and 289-ns conversion time. It supports ratio-metric referencing (VREFHI/VREFLO), simultaneous sampling across multiple channels via hardware triggers, and direct DMA transfer to RAM - all optimized for current/voltage feedback in high-bandwidth motor control loops executed by the TMS320F28062FPFPQ.

Is the TMS320F28062FPFPQ qualified for automotive applications?

Yes, the TMS320F28062FPFPQ carries AEC Q100 Grade 0 qualification for operation from –40°C to 125°C ambient temperature. It meets automotive reliability standards including stress testing, failure mechanism analysis, and lot traceability. The "Q" suffix explicitly denotes this qualification, making the TMS320F28062FPFPQ suitable for under-hood motor control, EV charging, and ADAS-related power systems.

What communication interfaces are integrated into the TMS320F28062FPFPQ?

The TMS320F28062FPFPQ integrates two SCI/UART modules, two SPI modules, one I²C bus, one McBSP, one enhanced CAN (eCAN) controller, and one USB 2.0 interface (full-speed device/host mode). These peripherals support daisy-chain motor control networks, isolated communication with gate drivers, firmware updates via USB, and diagnostics over CAN - all accessible through the TMS320F28062FPFPQ's 54 GPIO pins with programmable input filtering.
