The device is a serial access microcontroller designed for secure mobile applications. It 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 device 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 device features hardware accelerators for advanced cryptographic functions. The EDES peripheral provides a secure DES (Data Encryption Standard) algorithm implementation, while the NESCRYPT cryptoprocessor efficiently supports the public key algorithm. The AES peripheral ensures secure and fast AES algorithm implementation.
The device operates in the –25 to +85 °C temperature range and 1.8 V, 3 V and 5 V supply voltage ranges. A comprehensive range of power-saving modes enables the design of efficient low-power applications.
