Description

The ST33GxxxM (see Table 1) are serial access microcontrollers designed for machine-to-

machine (M2M) applications in the industrial environment. They incorporate the most recent

generation of ARM® processors for embedded secure systems. Their 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.

Cadenced at 25 MHz, the SC300™ core brings great performance and excellent code

The high-speed embedded Flash memory introduces more flexibility to the system.

The ST33GxxxM also offers a serial communication interface fully compatible with the

ISO/IEC 7816-3 standard (T=0, T=1) and a single-wire protocol (SWP) interface for

communication with a near field communication (NFC) router in SIM/NFC applications.

An SPI Master/Slave interface is also available for communication in non-SIM applications.

Three general purpose 16-bit timers are available; one is configurable as a watchdog.

The ST33GxxxM features hardware accelerators for advanced cryptographic functions. The

EDES peripheral provides a secure DES (Data Encryption Standard) algorithm

implementation, while the NESCRYPT cryptoprocessor efficiently supports the public key

algorithm. The AES peripheral ensures secure and fast AES algorithm implementation.

The device 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.

The ST33GxxxM is delivered in wafer form and in ECOPACK®-compliant DFN8 packages.

In order to meet environmental requirements, ST offers these devices in different grades of
