Please note, Texas Instruments has just released Revision E of pre-production silicon for the following SimpleLink™ devices:
- SimpleLink Sub-1 GHz CC1312R Wireless MCU supporting proprietary Sub-1 GHz development as well as the SimpleLink Sub-1 GHz stack
- SimpleLink Multi-Band CC1352R Wireless MCU supporting Sub-1 GHz and 2.4 GHz proprietary solutions as well as Bluetooth® low energy, Thread, and Zigbee
- SimpleLink Bluetooth® low energy CC2642R wireless MCU supporting Bluetooth® 5
- SimpleLink Multi-Standard CC2652R Wireless MCU supporting 2.4 GHz proprietary, Thread, Zigee, and Bluetooth® low energy
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:
- Revision E silicon will only be compatible with SDK v2.40.00.xx and later
- Revision C silicon will only be compatible with SDK v2.30.00.xx and earlier
- Revision E silicon is currently available on the TI store for the following devices:
- 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.
Reference the following chart for a summary of software compatibility:

Rev. C Silicon
No longer available on TI store
Please see the SDK documentation migration guide for guidance on migrating to the latest version of the SDK. This is also available in Resource Explorer on dev.ti.com: Migration GuideSeveral 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
