Product details
Overview
TMS320F28062UPFPS from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and 12-bit 3.46-MSPS ADC, designed for closed-loop motor control in industrial inverters and EV charging power modules. It features 64KB flash, 34KB RAM, 8 ePWM channels (4 HRPWM-capable), 3 eCAP, 2 eQEP, USB 2.0, and eCAN.
For engineers reviewing the TMS320F28062UPFPS datasheet, TMS320F28062UPFPS pinout, TMS320F28062UPFPS application, or TMS320F28062UPFPS equivalent, key selection criteria include HRPWM dual-edge modulation capability, on-chip temperature sensor, 128-bit security key, VCU support for CRC/Viterbi, and compatibility with InstaSPIN-FOC™ firmware libraries.
Technical Context
The TMS320F28062UPFPS implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory model, paired with a dedicated 32-bit floating-point CLA that runs control law code independently of the main CPU. Its VCU extends the instruction set for complex math, CRC, and Viterbi decoding - all accessible via DMA.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO references, analog comparators with internal 10-bit DACs routed directly to ePWM trip zones, and dual 4L-FIFO SCI/UART modules supporting asynchronous serial communication at up to 3 Mbps.
