Product details
Overview
F28P650DK6ZEJR 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, solar string inverters, and EV on-board chargers.
For engineers reviewing the F28P650DK6ZEJR datasheet, F28P650DK6ZEJR pinout, F28P650DK6ZEJR application, or F28P650DK6ZEJR equivalent, key selection criteria include lockstep safety support, EtherCAT SubDevice capability, CAN FD dual-controller integration, and nFBGA-256 (ZEJ) package compatibility with industrial thermal requirements (–40°C to 125°C).
Technical Context
The F28P650DK6ZEJR implements a dual-C28x architecture with independent CLA execution, enabling concurrent real-time signal processing: CPU1 handles primary control law execution while CPU2 operates in lockstep mode for functional safety validation, and the CLA offloads floating-point-intensive tasks like PWM modulation and observer calculations without CPU intervention.
Its analog subsystem integrates three 16-bit/12-bit ADCs (1.19 MSPS @16-bit), 11 windowed comparators with slope-compensated DAC references, and hardware oversampling (up to 128×) - all tightly coupled to ePWM and eCAP peripherals via dedicated crossbars to minimize latency in closed-loop motor and power converter control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
