描述 Description

The ST33G1M2SC 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 ST33G1M2SC also offers a serial communication interface fully compatible with the ISO/IEC 7816-3 standard (T=0, T=1) 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 ST33G1M2SC 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.
