dsPIC33C MPT Secure Digital Signal Controllers (DSCs)
dsPIC33 DSCs with Integrated Hardware Security Module
The dsPIC33C MPT family of secure Digital Signal Controllers (DSCs) includes an integrated secure subsystem to address the critical need to add security to automotive, industrial and IoT applications. Offering 100 MHz real-time performance and a rich feature set, dsPIC33C MPT secure DSCs are excellent options for embedded applications requiring time-critical function execution and fast deterministic response.
The security features available in dsPIC33C DSCs protect against remote digital attacks, while the physical anti-tampering and side-channel attack protections available in the integrated secure subsystem block access to embedded system credentials to provide extra security.
Why Choose dsPIC33C MPT DSCs for Your Design?

Security Features
ISO 26262 and IEC 61508 Functional Safety Ready
A connected safety-critical application is not safe if it is not secure. You can use our functional safety ready dsPIC33C MPT DSCs to design safety-critical applications targeting automotive ISO 26262 ASIL B or industrial IEC 61508 SIL 2 compliance. We offer these resources to support your development:
- Hardware safety features
- FMEDA and safety manual
- Functional safety diagnostic libraries
- Functional safety packages and development ecosystem
Automotive and AUTOSAR® Ready
In addition to being AEC Q100 Grade 1 qualified (−40⁰C to 125⁰C), dsPIC33C MPT DSCs are automotive and AUTOSAR ready. Take advantage of these resources for your automotive design:
- Support for AUTOSAR (4.3.x) from our third-party partners
- Production-ready ASIL B and ASPICE-compliant Microcontroller Abstraction Layer (MCAL) drivers
- AUTOSAR crypto driver support for the secure subsystem
Secure Provisioning
Avoid the high risks of exposing your secret keys and reduce the costs of mass production by leveraging our secure key provisioning service. Our Trust Platform provisioning service prevents your credentials from being exposed at any time during product development and production while also eliminating the need for you to have extensive knowledge and the necessary secure networks to handle cryptographic keys securely.
Adding Security Is Easy With dsPIC33C Secure DSCs
MPLAB Code Configurator
MPLAB Code Configurator (MCC) is a free graphical programming environment that generates C code to insert into your secure project. It supports a variety of application libraries that you can use to implement secure boot, secure firmware upgrades, node authentication and secure communication in your design.
TA-CryptoAuthLib Library in MCC
To help you develop secure applications, the TA-CryptoAuthLib Library is compatible with the secure subsystem in the dsPIC33C MPT family of secure DSCs and is supported within MCC. The TA-CryptoAuthLib Library is available under NDA. Use our request form or contact your Microchip sales team for more information.
Secure Boot and Secure Firmware Upgrade
The bootloader in MCC leverages hardware-based CodeGuard™ security and the Flash OTP feature available in dsPIC33C MPT DSCs and works with the secure subsystem to implement immutable secure boot and secure firmware upgrades.
Are You Ready to Get Started?
To prototype with the proposed development kits, use the tutorials and code examples within the Trust Platform Design Suite (TPDS) software available for Windows® and macOS® operating systems.
When you are ready to go to production, order the pre-provisioned devices and download the manifest file from www.microchipDIRECT.com or from our distribution partners. Upload the list of public credentials in the corresponding cloud account.
