产品概述
描述
The ST33Jxxx 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 ST33Jxxx provides high performance thanks to a fast SC300 processor, crypto-accelerators (DES, AES and MIFARE Classic® ) and improved Flash memory operations. Cadenced at 60 MHz, the SC300™ core brings great performance and excellent code density thanks to the Thumb®-2 instruction set.
Strong and multiple fault protection mechanisms ensure a guaranteed high-detection coverage that facilitates the development of highly secure software. This is achieved by using two CPUs in locked-step mode, error codes in sensitive memories and hardware logic.
