Product details
Overview
F28P650DK9NMR from Texas Instruments is a dual-C28x DSP + CLA real-time microcontroller for high-precision power electronics control, featuring 200MHz C28x CPUs (IEEE 754 double-precision FPU, TMU, VCRC), 1.28MB ECC-protected flash, 248KB parity-protected RAM, and 36 HRPWM channels with 150ps resolution - deployed in servo drives, string inverters, and EV DC fast charging stations.
For engineers reviewing the F28P650DK9NMR datasheet, F28P650DK9NMR pinout, F28P650DK9NMR application, or F28P650DK9NMR equivalent, key selection criteria include lockstep CPU2 support, EtherCAT SubDevice Controller integration, 169-ball nFBGA (NMR) package compatibility, and functional safety certification up to ASIL B/SIL 2.
Technical Context
The F28P650DK9NMR implements a deterministic dual-C28x architecture with lockstep comparison on CPU2 for fault detection, paired with an independent 200MHz CLA for parallel control law execution. Its analog subsystem integrates three 16-bit/12-bit ADCs (1.19MSPS/3.92MSPS), 11 windowed comparators with slope-compensated DAC references, and hardware oversampling (up to 128×) with outlier rejection.
Control peripherals include 36 ePWM channels with MINDB and ICL logic for multilevel converter topologies, seven eCAP modules (two with HRCAP), six eQEP interfaces, and 16 SDFM input channels. Communications include two CAN FD controllers, EtherCAT SubDevice Controller, USB 2.0, FSI (200Mbps), four SPI, two UART, two I²C, and PMBus.
