STMicroelectronics introduces two product families for cellular-phone SIM cards with features that allow mobile network operators to enhance differentiation and expand revenue growth by delivering richer services to subscribers. The ST32 and ST33 smart card processor families use the ARM Cortex-M3 32-bit processor architecture, and its SC300 secure version, combined with large embedded Flash memory capacities. All the devices use proprietary 90 nm embedded Flash technology, delivering lower power and smaller chip dimensions. The ST32 family uses the 32-bit ARM Cortex-M3 processor and contains two devices offering a choice of memory sizes. The ST33 family targets the high-end SIM market that requires the highest level of security. This family is based on the SC300 highly secure version of the ARM Cortex-M3 32-bit core.
