ST33G1M232bit ARM SC300 secure core with Mifare ClassicTM Accelerator, Nescrypt cryptoprocessor and SWP, SPI, GPIO interfaces
The ST33G1M2 is a serial access microcontroller designed for secure mobile applications that incorporates the most recent generation of ARM® processors for embedded secure systems. 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.
