Product details
Overview
TMS320F28069MPFPQ from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and VCU, designed for high-precision motor control and digital power conversion. It delivers 11.11-ns instruction cycle time, 128KB flash, 50KB RAM, 16-channel ePWM (8 HRPWM-capable), 3.46-MSPS 12-bit ADC, and AEC Q100 qualification for automotive inverter modules.
For engineers reviewing the TMS320F28069MPFPQ datasheet, TMS320F28069MPFPQ pinout, TMS320F28069MPFPQ application, or TMS320F28069MPFPQ equivalent, key selection criteria include HRPWM dual-edge modulation capability, on-chip temperature sensor, 128-bit code security, USB 2.0 device/host support, and Q-grade thermal range (–40°C to 125°C) for under-hood automotive power electronics.
Technical Context
The TMS320F28069MPFPQ implements a Harvard architecture C28x CPU with atomic operations and unified memory programming, enabling deterministic real-time execution. Its CLA executes floating-point control law code independently of the main CPU, while the VCU accelerates complex math, CRC, and Viterbi operations-critical for field-oriented control (FOC) and predictive current regulation.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric reference support, analog comparators routed directly to ePWM trip zones, and six-channel DMA for zero-CPU-overhead data movement. The device uses internal voltage regulation for single 3.3-V supply operation and features two zero-pin oscillators plus PLL for flexible clock tree configuration.
