Product details
Overview
TMS320F28062PNT from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and advanced motor control peripherals including 16 ePWM channels (8 HRPWM-capable), 3 eCAP, 4 HRCAP, 2 eQEP, and a 12-bit 3.46-MSPS ADC. It delivers deterministic closed-loop performance for digital power and motor drive applications requiring precise timing, analog sensing, and fast interrupt response.
For engineers reviewing the TMS320F28062PNT datasheet, TMS320F28062PNT pinout, TMS320F28062PNT application, or TMS320F28062PNT equivalent, this device is selected for high-precision PWM generation, real-time sensor acquisition in inverters, and embedded control where floating-point math acceleration and dual-edge HRPWM modulation are required.
Technical Context
The TMS320F28062PNT implements a Harvard-architecture C28x CPU with atomic instruction support and unified memory mapping, enabling efficient C/C++ execution. Its CLA operates independently of the main CPU to offload time-critical control law computations using native 32-bit floating-point arithmetic.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO referencing, analog comparators with internal 10-bit references routed directly to ePWM trip zones, and enhanced ePWM modules supporting dual-edge frequency modulation for high-resolution switching control.
