The K82 sub-family extends Kinetis products with new hardware security mechanisms including decryption from serial NOR flash memory, AES128, AES256 with side band attack protection, and Elliptical Curve Cryptography acceleration. These advancements are done while maintaining a high level of compatibility with previous Kinetis devices. The MCUs range in total flash space upto 256KB and have 256KB of SRAM. The QuadSPI interface supports connections to Non-Volatile Memory for data or code. The extended memory resources and new security features allow developers to enhance their embedded applications with greater capability.
