32-bit ARM-Based MCUs for cellular-phone SIM cards

ST Microelectronics introduced two new product families, ST32 and ST33, for cellular-phone SIM cards.

These 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.

Features are listed below:

1. 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
2. The ST33 family provides highest level of security.
3. The ST33 family is based on the SC300 highly secure version of the ARM Cortex-M3 32-bit core.
4. The ST33F1M, 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 cryptographic coprocessor.
5. The large embedded-Flash memory size available will allow telecom operators to enrich the multimedia content of their SIM cards.
6. All of the new devices meet industry standards for SIM card interfaces and communication.
7. The devices also support standard power-management features laid down for cellular handsets

Availability: The ST32F416 and ST32F512 are sampling now, with production
volumes by early 2009.
The ST33F1M will sample by Feb 2009, with production volumes by mid 2009.
