[FAQ] CC13x2, CC26x2 Revision E and SDK version compatibility

Please note, Texas Instruments has just released Revision E of pre-production silicon for the following SimpleLink™ devices:


Additionally, the following LaunchPads have been updated with Revision E silicon:

To determine the silicon revision of your device, please reference the following diagram:

With the pre-production release of Revision E silicon, Texas Instruments would like to highlight several key compatibility considerations:

  • All silicon released before the device production will be “x” marked and can either be Revision C or Revision E
  • All silicon released post-device production will not have the “x” marking and will be Revision E or later.

All users must migrate to the “non-X”, Revision E silicon immediately after RTM to develop with the latest features and ensure software and hardware compatibility.

Several things will not change between Revision E silicon and Revision C silicon:

  • Device pin out
  • Overall functionality and behavior of the device

Several things will change between Revision E silicon and Revision C silicon:

  • Errata
  • TI will embed the latest software into ROM to increase available flash for application development. This includes:
    • BLE Stack
    • TI-RTOS
    • 15.4 high layer MAC
