The TI C2000 C/C++ Compiler and Assembly Language Tools support development of applications for TI C2000 Microcontroller platforms, including the Concerto (F28M3xx), Piccolo (280xx), Delfino Floating-Point (283xx), and C2000 Fixed-Point (2823x/280x/281x) Microcontroller devices.
Available in release 20.12.0.STS:
- Live Firmware Update feature for C28/CLA firmware update support
- Generate CRCs over memory ranges
- C28 has more efficient data accesses for lower 16-bits of memory when using location attribute or literal addresses.
- The Integer Division Unit (--idiv_support=idiv0) has performance updates.
- CLA has a performance improvement with more efficiently loading 16-bit constants.
- Enumerated type changes.
- Misra support deprecated
- Available in release 20.2.0.LTS:
- Hex utility tool new option --cmac (cipher-based message authentication protocol) will apply cmac algorithm to user defined regions and generate cmac tags for secure boot support.

Long-term and short-term support
Long-term support (LTS) releases are actively maintained for approximately two years with reported defects being repaired as follows:
- Production stop defects are addressed within 2 weeks,
- Critical defects are addressed within 90 days, and
- Defect repairs are proactively applied to each release stream
- Only production stop defects may cause patch releases to be created,
- Patch releases for STS releases will not be planned, and
- Defect repairs will not be proactively applied to each release stream
- For more information about the distinction between LTS and STS compiler releases, please see the article: Introduction to LTS and STS Compiler Releases
- Optimizing C/C++ Compiler
- C/C++ standard header files
- C/C++ runtime libraries
- Object file display and manipulation utilities
