STMicroelectronics ST32 and ST33 Smart Card Processors

STMicroelectronics (NYSE: STM) recently announced the ST32 and ST33 smart card processor families for cellular phone SIM cards. The features enabled by the two new families enable mobile network operators to enhance differentiation and expand revenue growth by delivering richer services to subscribers. The ST32 and ST33 smart card processors feature the ARM Cortex-M3 32-bit processor architecture, and its SC300 secure version, combined with large embedded-Flash memory capacities. All the new devices use ST’s 90nm embedded Flash technology, delivering the combined benefits of increased capabilities, lower power, competitive price, and smaller chip dimensions. The ST32F416 and ST32F512 are sampling now, with production availability scheduled for early 2009. The ST33F1M will begin sampling in February 2009, with volume ramp-up expected in mid 2009.

The ST32 family uses the 32-bit ARM Cortex-M3 processor and contains two devices offering a choice of memory sizes. The ST32F416 and ST32F512 offer 416 Kbytes and 512 Kbytes of embedded Flash, respectively, and address the 128 K and 256 K 2G and 3G markets. Additional ST32 devices will be introduced with lower memory densities in the future.

The ST33 family targets the high-end SIM market, which requires the highest level of security. This family is based on the SC300 highly secure version of the ARM Cortex-M3 32-bit core. The ST33F1M, the first product in this range, features 1.2 Mbytes of embedded Flash with 30 Kbytes of RAM, an SWP (Single-Wire Protocol) interface for NFC (Near Field Communication) connectivity, and the most advanced cryptographic coprocessor (Nescrypt). With its intrinsic security level and wide availability of interfaces, the ST33F1M targets innovative (U)SIM markets such as Mobile Banking and Mobile TV. In addition, the large embedded-Flash memory size available will allow telecom operators to enrich the multimedia content of their (U)SIM cards.

All of the new devices meet industry standards for SIM card interfaces and communication, including ISO7816-3. In addition, ST33F1M also targets the highest security levels, such as CC-EAL5+ and EMVCo certifications. The devices also support standard power-management features laid down for cellular handsets, and achieve current consumption defined by GSM and ETSI standards.
