ST32F32A:ST32 Contact ARM Cortex-M3 Secure Microcontroller

The ST32F32A 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 320 Kbyte memory introduces more flexibility to the system.

The ST32F32A also offers a serial communication interface fully compatible with the ISO 7816-3 standard (T=0, T=1) for smartcard applications.

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 ST32F32A 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.

In order to meet environmental requirements, ST offers these devices in different grades of ECOPACK®packages, depending on their level of environmental compliance. ECOPACK®specifications, grade definitions and product status are available at: www.st.com. ECOPACK®is an ST trademark.
