Conclusion

This application note gives an introduction to the AES hardware accelerator embedded in

STM8L16x microcontrollers which can be used for data encryption/decryption with minimal

CPU load and memory usage. The main operating modes have been presented in Section 1

on page 3.

A description has been given of the software available for the AES with this application note.

Section 2 on page 13 described the peripheral driver with an abstraction layer for easy use

of the peripheral, Section 3 on page 15 described a set of examples that can be used as a

quick start for developing your own code and an in-depth example using AES block chaining

modes.
