Microchip’s dsPIC33CK family of secure digital signal controllers (DSCs) with integrated Hardware Security Module (HSM) features a single 100 MHz dsPIC® DSC core with integrated DSP, enhanced on-chip peripherals and secure subsystem.

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

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 CodeGuard Flash Security (immutable secure boot) and Flash OTP by ICSP™ Write Inhibit 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 dsPIC33C DSCs such as CodeGuard based Immutable Secure Boot, Flash OTP and others 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. The secure DSCs provide robust security measures for industrial and automotive environments, including code authentication (aka secure boot), message authentication via MAC generation, support for trusted firmware updates, Qi 1.3/2.0 wireless charging authentication, multiple key management protocols including TLS and other root-of-trust based operations to enable a high level of security for industrial and automotive systems. Additionally, these controllers enable developing secure power supplies with digital power capabilities satisfying the security requirement of the Open Compute Project (OCP) compliant power supply implementing SPDM protocol.

These DSCs enable the design of high-performance, precision motor control systems that are more energy efficient, quieter in operation and provide extended motor life. They can be used to control BLDC, PMSM, ACIM, SR and stepper motors. These DSCs are also ideal for switched mode power supplies such as AC/DC, DC/DC, UPS and PFC, providing high-precision digital control of Buck, Boost, Fly-Back, Half-Bridge, Full-Bridge, LLC and other power circuits to reach the highest possible energy efficiency. These devices are also ideal for advanced sensing and control, touch, high-performance general-purpose and robust applications.

The dsPIC33CK product family has many hardware features that help simplify functional safety certifications for ASIL-B and SIL-2 focused automotive and industrial safety-critical applications. The family offers ISO 26262 and IEC 61508 Functional Safety packages containing FMEDA report, safety manual, diagnostic libraries and more. Learn more about Functional Safety capabilities including hardware, software, and supporting collateral.
