Description

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.

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.

Note:

For MIFARE library usage, please, refer to the ST33G System ROM user manual.
