Description

The ST33GxxxA (see Table 1) is a serial access microcontroller designed for secure mobile

applications that incorporates the most recent generation of ARM® processors for

embedded secure systems. Its 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.

The SC300™ core brings great performance and excellent code density thanks to the

Thumb®-2 instruction set.

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

The ST33GxxxA 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.

The ST33GxxxA 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 ST33GxxxA’s automotive grade is AEQ100 compliant and provides user Flash memory

capability up to 500 kcycles with 15 years’ data retention.

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.
