PIC32CX  high performance micro-controller series features a 32-bit ARM® Cortex®-M4 processor with Floating Point Unit (FPU), running up to 120 MHz ,up to 1 MB Dual Panel Flash with ECC, and up to 256 KB of SRAM with ECC .It also adds a 10/100 Ethernet MAC and 2 CAN-FD ports targeted for industrial automation ,automotive applications and general purpose applications requiring Wired connectivity. Flash has an OTP region that be used for developing immutable secure boot. It also offers secure debug, chip erase protection, IP Protection and Boot Protect feature.

Common Criteria Joint Interpretation Library (JIL) high-rated secure subsystem provides hardware-based cryptographic key storage and crypto accelerators for multiple asymmetric, symmetric, and hashing security protocols. The secure subsystem combined with MCU's integrated security features supports an ultra-secure method for key agreement, sign-verify authentication for automotive in-vehicle networking, industrial and consumer applications. The security features in the PIC32CX SG MCUs protect against remote digital attacks while the integrated secure subsystem provides extra security with physical anti-tampering and side channel attack protections to block access to embedded system credentials. Usecases Supported include code authentication (aka secure boot), message authentication via MAC generation, trusted firmware updates, multiple key management protocols including TLS and other root-of-trust based operations.

The documentation and additional resources related to the secure subsystem is available under NDA. Contact your local Microchip sales team for more information or our Client Success Team (Schedule a Call) to get assistance with your design.
