描述 Description

The device is a serial access microcontroller designed for secure mobile applications. It incorporates the most recent generation of ARM processors for embedded systems. Its SecurCore? SC000? 32-bit RISC core is built on the Cortex? M0 core with additional security features to help to protect against advanced forms of attacks. The SC000? core brings great performance and excellent code density thanks to the Thumb?-2 instruction set. The CPU interfaces with the on-chip RAM, ROM and NVM via a 32-bit internal bus.

The high-speed, 480-Kbyte, embedded Flash memory introduces more flexibility to the system.

The device also offers a serial communication interface fully compatible with the ISO 7816-3 standard (T=0, T=1) for smartcard applications. In addition, it includes two general-purpose 16-bit timers, an ISO 3309 CRC calculation block and a watchdog timer. Finally, it has a hardware Data Encryption Standard (DES) accelerator that the user can use to optimize the application performance.

The device operates in the –25 to +85 °C temperature range, and the 1.8 V and 3 V supply voltage ranges. A comprehensive range of power-saving modes enables the design of efficient low-power applications.

The device is delivered in D18 micromodules. It is also available in wafers.
