Arm SecurCore SC300

The Arm SecurCore SC300 processor is designed specifically for high-performance smartcard and embedded security applications. 


The SC300 combines the benefits of the industry standard Cortex-M3 processor with the proven security features of Arm SecurCore processors. This enables a high assurance level certification for security-critical applications. Arm SecurCore processors are the most widely licensed 32-bit processors for smartcards worldwide. The programmers’ model is the same as the Cortex-M3. Therefore, the Cortex-M3 documentation listed below can be used for software development. However, explanation of anti-tampering features requires a SecurCore NDA.

Key benefits

  • High performance. The processor executes the Thumb-2 instruction set, including hardware division, single cycle multiply, and bit-field manipulation with low dynamic power.

  • Fast time to market. Based on the same architecture as the industry standard Cortex-M3, software development is straightforward.

  • Ecosystem. Developers also benefit from the Arm partnership extensive ecosystem of embedded tools, software, and knowledgebase.

** The first result abides by all of the ‘ground rules’ laid out in the Dhrystone documentation. The second result permits inlining of functions, not just the permitted C string libraries. The third result also permits simultaneous (multi-file) compilation. All are with the original (K&R) v2.1 of Dhrystone.
