Product details
Overview
TMS320F28067PZPS 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 - deployed in industrial inverters, servo drives, and EV charging power modules.
For engineers reviewing the TMS320F28067PZPS datasheet, TMS320F28067PZPS pinout, TMS320F28067PZPS application, or TMS320F28067PZPS equivalent, key selection criteria include HRPWM dual-edge modulation capability, on-chip VCU for CRC/Viterbi acceleration, 54 GPIO with input filtering, USB 2.0 support, and 125°C operation with AEC-Q100 qualification.
Technical Context
The TMS320F28067PZPS implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory mapping, coupled to a dedicated 32-bit floating-point CLA that runs control law code independently of the main CPU. Its clock system integrates two zero-pin oscillators, PLL-based frequency synthesis, and missing-clock detection.
Peripheral integration includes a 12-bit dual-sample-and-hold ADC with ratio-metric reference support (VREFHI/VREFLO), three analog comparators with internal 10-bit DACs routed directly to ePWM trip zones, and enhanced ePWM modules supporting frequency-modulated dual-edge control for high-fidelity motor phase timing.
