  • active Active

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 SC000™ core brings great performance and excellent code density thanks to the Thumb®-2 instruction set.

MR31 and MG31 devices implement MIFARE DESFire™ EV1 or MIFARE Plus™ (including MIFARE Classic™) technology. MIFARE and DESFire are registered trademarks of NXP B.V. in the U.S. and other jurisdictions, and are used under licence.

An RF interface including an RF universal asynchronous receiver (RF UART) enables contactless communication up to 848 Kbps compatible with the ISO/IEC 14443 Type A and Type B standards.

Very High Bit Rates (VHBR) up to 3.4 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 1.8V, 3V and 5V 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.
