Overview
TMS320F28P650DK6PTP 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, 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 TMS320F28P650DK6PTP datasheet, TMS320F28P650DK6PTP pinout, TMS320F28P650DK6PTP application, or TMS320F28P650DK6PTP equivalent, key selection criteria include lockstep safety support, EtherCAT SubDevice capability, CAN FD dual-controller integration, and 176-pin HLQFP thermal performance at 125°C ambient.
Technical Context
The TMS320F28P650DK6PTP implements a deterministic real-time control architecture with two independent 200MHz C28x DSP cores (one lockstep-capable), a dedicated 200MHz CLA CPU, and tightly coupled analog subsystems-including three 16-bit/12-bit ADCs (1.19MSPS @16-bit), 11 windowed comparators with slope-compensated DAC references, and hardware oversampling up to 128×.
Its control peripherals include 36 ePWM channels with Minimum Dead-Band Logic (MINDB) and Illegal Combo Logic (ICL), seven eCAP modules (two with HRCAP), six eQEP interfaces, and a Configurable Logic Block (CLB) with six logic tiles-enabling FPGA-like custom PWM generation and encoder interface offload without external logic.
