The CEC173x Trust Shield family is the Real Time Root of Trust Controller for Servers, Telecommunications, Networking and Industrials. The CEC173x is a highly-configurable, mixed-signal, advanced I/O controller. It contains a 32-bit 96MHz ARM® Cortex- M4 processor core with closely-coupled memory for optimal code execution and data access. The immutable Boot ROM, embedded in the design, is used to store the power on/boot sequence and APIs available during run time. When VTR_REG power is applied to the device, the secure boot loader API is used to download the firmware image from internal Flash storage. Programming capability for this Flash is provided by various means, thereby allowing system designers to customize the device’s behavior while maintaining the integrity of the image by cryptographic signatures.
