Winbond’s TrustME® Secure Flash Memory offers robust code and data storage protection through external Secure Flash Memory, enhancing system trusted boot and firmware update reliability. In today’s security-conscious era, providing reliable solutions for trusted boot and firmware updates has become a fundamental requirement for IoT security. TrustME® series not only achieves Common Criteria certification but also ensures secure chip production, software design, and key provisioning services for various connected systems right from the manufacturing stage.
TrustME® series is designed to meet the growing security demands, particularly in IoT devices that require high levels of data protection and system integrity. Leveraging its advanced secure architecture, TrustME® series supports Post-Quantum Cryptography (PQC) and functional safety standards, effectively preventing unauthorized access and data tampering. This ensures that systems remain highly secure during every boot and firmware update cycle.
Additionally, Winbond’s TrustME® Secure Flash Memory provides multi-layer access control and key management, allowing multiple independent memory partitions, each with dedicated keys and encryption policies. This capability is particularly critical for applications with high security requirements, such as automotive electronics, industrial control systems, and embedded devices.
