The ST32F384 is a serial access microcontroller designed for secure mobile applications that incorporates the most recent generation of ARM processors for embedded systems. Its Cortex™-M3 32-bit RISC core operating at a 20-MHz frequency brings great performance and excellent code compacity to the application thanks to the Thumb®-2 instruction set.
The high-speed embedded Flash 384-Kbyte memory introduces more flexibility to the system.
The ST32F384 also offers a serial communication interface fully compatible with the ISO/IEC 7816-3 standard (T=0, T=1) .
Two general-purpose 16-bit timers are available.
A hardware Data Encryption Standard (DES) accelerator can be used to the user to optimize the application performance. A software library is provided for Advanced Encryption Standard (AES) implementation.
The ST32F384 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.主要特性
