Description

The ST32GxxxA (see Table 1) is a serial access microcontroller designed for machine-to-

machine (M2M) applications in the car 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 ST32GxxxA 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 ST32GxxxA 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.
