32bit ARM SC300 secure core with SPI interfaces and Nescrypt cryptoprocessor

The SC33F1M0 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.

Cadenced at 22.5 MHz, the SC300™ core brings great performance and excellent code density thanks to the Thumb®-2 instruction set.

The high-speed embedded Flash with up to 1280 Kbytes of memory introduces more flexibility to the system.

The SC33F1M0 also offers a serial communication interface fully compatible with the ISO/IEC 7816-3 standard (T=0, T=1).

An SPI Slave interface is also available for communication in non-SIM applications. Note that this interface is not available when ISO/IEC 7816 communications are required.

Three general purpose 16-bit timers are available; one configurable as a watchdog.

The SC33F1M0 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 ST33F 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.
