Provides maximum size embedded memory, maximum clock speed, and built-in encryption accelerator

STMicroelectronics has introduced the ST33J2M0, the first product of the third generation of the industry-leading security microcontroller ST33 series based on the 32-bit ^{ARM® SecurCore®} SC300™ processor.

This product takes security microcontrollers to the next level by providing 2 megabytes of flash program memory, the largest in the industry. This is because the memory size has nearly doubled compared to existing security microcontrollers. For cost efficiency, ST’s state-of-the-art 40nm embedded flash technology is applied to the entire process. It features an integrated cryptographic accelerator boasting the best performance, boasting the industry’s fastest clock speed and delivering top performance suitable for fast application execution.

In addition, it features a new hardware architecture that provides robust multi-fault protection mechanisms for the CPU, memory, and bus, enabling support for the development of highly secure software.

Application of Embedded Secure Element (eSE)

The latest ST33 product family meets the growing demand for security applications, such as embedded Secure Elements (eSE), Single Wire Protocol (SWP) SIMs for NFC applications, and embedded Universal Integrated Circuit Cards (UICC). This function is essential for protecting transaction activities in various fields, such as payment applications, the Internet of Things, and wearable consumer products, as well as Industry 4.0 factory automation standards, M2M communication, V2X, and in-vehicle communication.

Marie-France Florentin, Group Vice President and Head of the Security Microcontrollers Group at ST, said, “ST’s third-generation security microcontrollers are a versatile platform designed to be suitable for a multitude of security applications across various electronic products,” adding, “The ST33J2M0 can support a wide range of sensitive applications, including finance, transportation, authentication, biometrics, M2M, and automotive, with a single device.”

The ST33J2M0 is equipped with a variety of hardware accelerators for advanced encryption functions. It can securely implement the DES (Data Encryption Standard) algorithm with the EDES peripheral and efficiently support public key algorithms with the NESCRYPT encryption processor. The AES peripheral can securely and quickly implement the AES algorithm.

Samples of the ST33J2M0 are available in wafer, VQFN, and WLCSP packages, and information regarding sample requests and pricing can be obtained through ST Korea.
