  • Each subsystem consists of a C28x CPU and a parallel control law accelerator (CLA), each running at 200 MHz.
  • A resistor with a value from 2.2 kΩ to 10 kΩ should be placed between XRS and VDDIO.
  • If a capacitor is placed between XRS and VSS for noise filtering, it should be 100 nF or smaller.

Topics covered by the datasheet

The document includes sections related to:

  • F28377D-SEP Dual-Core Real-Time Microcontroller datasheet (Rev. A)
  • Package Information

Engineering review checklist

  • Confirm supply rails, clock limits, memory size, peripheral mapping and I/O voltage compatibility.
  • Check package pinout, boot configuration, programming interface and silicon-revision errata.
  • Budget decoupling, thermal margin, startup timing and firmware recovery behavior before release.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
