The ST33Jxxx is a serial access microcontroller designed for secure mobile applications. It 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 ST33Jxxx provides high performance thanks to a fast SC300 processor, crypto-accelerators and improved Flash memory operations.
Cadenced at 60 MHz, the SC300™ core brings great performance and excellent code density thanks to the Thumb®-2 instruction set.
Strong and multiple fault protection mechanisms ensure a guaranteed high-detection coverage that facilitates the development of highly secure software. This is achieved by using two CPUs in locked-step mode, error codes in sensitive memories and hardware logic.
The ST33Jxxx 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 Secure Element (SE) applications. The device also includes an SPI Master/Slave interface as well as two I2C Master/Slave interfaces for communication in non-SIM applications: SPI Slave up to 26 MHz, SPI Master up to 13 MHz, I2C Slave High-speed mode up to 2.4 Mbit/s, I2C Master Fast-mode plus up to 1 Mbit/s. Up to four of these interfaces can run independently.
Three general-purpose 16-bit timers as well as a watchdog timer are available.
One permanent timer (PMT) with a count capability up to 8 days in low-power mode is available.
The ST33Jxxx features hardware accelerators for advanced cryptographic functions. The EDES peripheral provides a secure DES (Data Encryption Standard) algorithm implementation, while the NESCRYPT crypto-processor efficiently supports the public key algorithm. The AES peripheral ensures secure and fast AES algorithm implementation.
The ST33Jxxx operates in the –25 to +85 °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 such as Hibernate mode down to 1 μA for embedded solutions and Standby mode for SIM or embedded applications.
In terms of application, ST offers optional software packages: NesLib public key cryptographic library and MIFARE4Mobile® v2.1.1 with MIFARE® Classic, DESFire® EV1.
