Its SecurCore® SC300™ 32-bit RISC core is built on the Cortex™ M3 core with additional security features to help to protect against advanced forms of attacks. The SC300™ core brings great performance and excellent code density thanks to the Thumb®-2 instruction set. The high-speed embedded Flash memory introduces more flexibility to the system. The ST33G1M2 also offers a serial communication interface fully compatible with the ISO/IEC 7816-3 standard (T=0, T=1) and a single-wire protocol (SWP) interface for communication with a near field communication (NFC) router in SIM/NFC applications. An SPI Master/Slave interface is also available for communication in non-SIM applications. The ST33G1M2 features hardware accelerators for advanced cryptographic functions. The EDES peripheral provides a secure DES (Data Encryption Standard) algorithm implementation, while the NESCRYPT crypto-processor efficiently supports the public key algorithm. The AES peripheral ensures secure and fast AES algorithm implementation. The ST33G family operates in the –25 to +85°C temperature range and 1.8V, 3V and 5V supply voltage ranges. A comprehensive range of power-saving modes enables the design of efficient low-power applications. Software development tools description Dedicated SecurCore® SC300™ software development tools are provided by ARM and Keil. This includes the Instruction Set Simulator (ISS) and C compiler. The documentation is available on the ARM and Keil web sites. Moreover, STMicroelectronics provides: A time-accurate hardware emulator controlled by the Keil debugger and the STMicroelectronics development environment. A complete product simulator based on Keil’s ISS simulator for the SecurCore® SC300™ CPU. A secured ROMed Flash Loader with very high-speed software downloading capabilities.
