Description

Designed for secure ID and banking applications, the ST31P320 and ST31P450 devices are serial access

help to protect against advanced forms of attacks.

Cadenced at 55 MHz, the SC000™ core brings great performance and excellent code density thanks to the

An RF interface including an RF universal asynchronous receiver (RFUART) enables contactless communication

up to 848 kbps compatible with the ISO/IEC 14443 Type A standard.

The devices also offer a serial communication interface fully compatible with the ISO/IEC 7816-3 standard (T=0,

T=1).

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

The devices feature hardware accelerators for advanced cryptographic functions. The AES accelerator provides a

high-performance implementation of the AES-128, AES-192 and AES256 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 devices operate in the –25 to +85 °C temperature range, in the 2.7 V and 5.5 V supply voltage ranges in

Contact mode, and comply with ISO/IEC 14443 specification limits. A comprehensive range of power-saving

modes enables the design of efficient low-power and contactless applications.
