ST32G256M：Enhanced ST32 secure micro for M2M
The ST32GxxxM is a serial access microcontroller designed for machine-to-machine (M2M) applications in the industrial environment that incorporates the most recent generation of ARM®processors for embedded systems. Its Cortex®-M3 32-bit RISC core operating at a 15-MHz frequency brings great performance and excellent code compacity to the application thanks to the Thumb®-2 instruction set.
The 512-Kbyte high-speed embedded Flash memory introduces more flexibility to the system. This Flash memory has an improved cycling capability compared to the ST32F512-M.
The ST32GxxxM 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 ST32GxxxM operates in the –40 to +105 °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.
