CoreLink SIE-200 provides IP blocks built on top of the AMBA 5 AHB5 interface that extends TrustZone security to the system. The interconnect and TrustZone controllers provide a hardware-enforced isolation between secure and non-secure applications. The interconnectis configurable to support multiple system architectures, enabling designers to tailor each design to suit a specific application.

As CoreLink SIE-200 is based on the AHB5 protocol, it enables per-transaction security signaling through the system. This allows for hardware-assisted security partitioning of the system with efficient use of memory and peripherals across secure and non-secure applications.Advanced power management features based on the AMBA Low Power Interface enable parts of an MCU to be powered down when not in use, allowing for longer battery life.

Software programmable TrustZone controllers provide hardware enforced partitioning of system resources (memory and peripherals) that can be efficiently and securely shared between secure and non-secure applications.

CoreLink SIE-200 IP provides the lowest-risk route to building Armv8-M SoCs. The CoreLink SIE-200 IP is co-developed and co-tested with Arm v8-M processors. The architecture of the TrustZone controllers in CoreLink SIE-200 provide compatibility with the Arm v8-M software and tools ecosystem including support from Keil MDK, ArmM Socrates IP Tooling, Arm mbed OS, and multiple RTOS.
