  • active 活性

Designed for secure ID and banking applications, the SR31Z052 is a serial access microcontroller that incorporates the most recent generation of ARM® processors for embedded secure systems. Its 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 SecurCore® SC000™ core brings great performance and excellent code density thanks to the ARM® Thumb®-2 instruction set.

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 and Type B standards.

Very High Bit Rates (VHBR, Tx = 6.8 Mbps and Rx = 1.7 Mbps) are possible in Type B frames.

A Simultaneous mode where contactless communication can be enabled while the device is in Contact mode is also available.

The SR31Z052 also offers a serial communication interface fully compatible with the ISO/IEC 7816-3 standard (T=0, T=1).

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

The SR31Z052 features 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 crypto-processor efficiently supports the public key algorithm with native operations up to 4096 bits long.

The SR31Z family operates in the –25 to +85 °C temperature range, at 3 V and 5 V supply voltage ranges in Contact mode and complies with ISO/IEC 14443 specification limits. A comprehensive range of power-saving modes enables the design of efficient low-power and contactless applications.
