The MAXQ1065 is a dedicated security coprocessor designed to fortify embedded systems. It integrates cryptographic functions for establishing root-of-trust, robust authentication, data confidentiality, and integrity. Secure boot and firmware update mechanisms are incorporated to mitigate threats. 

It features 8KB of data storage allowing users to store certificates, keys, and other data. It also provides a configurable output pin and a tamper input pin. Moreover, it features the SPI protocol to communicate with external hardware. Additionally, the device offers secure communication capabilities, making it suitable for applications demanding stringent security, such as IoT, medical, and automotive domains.

Low-Power Module Best Suited for Portable and Battery-Operated Embedded Systems

The MAXQ1065 controller offers a low-power option for modern embedded systems. It operates at just 3.3Volts and 100nA and can work in a wide temperature range of -40 to +105 degrees Celsius It connects with any compatible host microcontroller via the SPI communication module. The module operated in multiple configurations at 10MHz. 

Moreover, it’s a 12-pin device with 3mm x 3mm packaging and a reduced footprint. Therefore, it fits with most miniaturized embedded systems like wearable devices, medical devices, and IoT systems. Its small form factor and low power consumption make it a viable option for long-term deployments. 

The controller features an ECC Computer Engine using the Curve NIST P-256, a True Random Number Generator (TRNG), and many device-level security protocols to detect system-level intrusions. 

Advanced Security Features for Applications in Embedded Systems

The MAXQ1065 is a versatile security coprocessor that significantly enhances the security posture of connected embedded systems across diverse sectors. Essentially, it serves as a robust security hardware against cyber threats for infrastructures and connected devices, including network nodes, routers, and gateways. Due to its advanced security features, the controller is most suited for the following applications:

• Secure Communication - Facilitates secure data exchange by implementing robust encryption protocols like TLS and handling key management efficiently. It ensures data confidentiality and integrity during transmission. Moreover, it protects against eavesdropping and tampering.

• Secure Data Storage - Encrypts sensitive data at rest, eventually safeguarding information from unauthorized access, even if the device is compromised. It prevents data breaches and unauthorized disclosure and protects intellectual property and confidential information.

• Mutual Authentication - Enables secure identity verification, preventing unauthorized access and ensuring data integrity. Hence, it establishes trust between communicating parties and mitigates man-in-the-middle attacks.

• Certificate Management - Securely stores and manages digital certificates, essential for authentication and encryption. Therefore, it simplifies certificate lifecycle management. Moreover, it ensures the validity and trustworthiness of certificates.

• Anti-cloning, Anti-counterfeiting, Feature, and Usage Control - Provides mechanisms to protect intellectual property, controls product usage, and prevents unauthorized replication of devices and software. It also facilitates flexible licensing and feature control.

• System-Level Tamper Protection and Integrity - Detects unauthorized modifications to the system, safeguarding its integrity. Hence, it protects against malicious attacks and tampering and ensures system reliability and trustworthiness.

• Secure Boot, Secure Firmware Update -  Guarantees that only authorized software is loaded and that firmware updates are secure. Therefore, it prevents bootloaders and firmware from being compromised. Eventually, it protects against supply chain attacks.

Since these functions are primarily required in most computing areas, its applications span industrial IoT, SCADA, medical equipment, building and home automation, smart cities, and smart metering.
