Description

ST31H320, ST31H256, ST31H192, ST31H128

Description

Designed for secure ID and banking applications, the ST31H platform products (ST31H320,

ST31H256, ST31H192 and ST31H128) are serial access microcontrollers that incorporate

the most recent generation of ARM processors for embedded secure systems. Their

SecurCore® SC000™ 32-bit RISC core is built on the Cortex™ M0 core with additional

security features to help to protect against advanced forms of attacks.

Cadenced at 28 MHz, the SC000™ core brings great performance and excellent code

density thanks to the Thumb®-2 instruction set.

The ST31H platform offers a serial communication interface fully compatible with the

ISO/IEC 7816-3 standard (T=0, T=1).

Three 16-bit general-purpose timers, as well as a watchdog timer, are available.

The devices feature hardware accelerators for advanced cryptographic functions. The AES

accelerator provides a high-performance implementation of AES-128, AES-192, AES-256

algorithms. The 3-key Triple DES accelerator (EDES+) peripheral enables Cipher Block

Chaining (CBC) mode, fast DES and triple DES computation based on three key registers

and one data register, while the NESCRYPT cryptoprocessor efficiently supports the public

key algorithm with native operations up to 4096 bits long.

The ST31H platform operates in the –25 to +85 °C temperature range at 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.

Software development tools description

Dedicated SecurCore® SC000™ software development tools are provided by ARM® and

Keil . This includes the Instruction Set Simulator (ISS) and C compiler. The documentation

is available on the ARM and Keil web sites.

Moreover, STMicroelectronics provides:



A time-accurate hardware emulator controlled by the Keil debugger and the ST

development environment.

A complete product simulator based on Keil’s ISS simulator for the SecurCore®

SC000™ CPU.
