Renesas Develops RS-4 Series 16-Bit Secure MCUs for Smart Cards

Renesas Technology has announced the development of the new RS-4 Series of 16-bit secure MCUs for smart card applications in fields requiring a high level of security, such as credit or debit cards issued by banks or finance companies and ID cards. The new RS-4 Series of 16-bit secure MCUs is the successor to the AE-4 Series of 16-bit secure MCUs, which has a solid track record. The RS-4 Series maintains CPU instruction code compatibility with its predecessor while delivering approximately five times the processing performance. This increased processing power enables the RS-4 Series to handle tasks that were beyond the AE-4 Series and would previously have required developers to employ a 32-bit MCU. The new secure MCUs can perform complex processing at high speed, making it possible for them to run a multi-application OS such as Java Card or MULTOS faster, which is necessary to implement multiple functions on a single smart card.

The RS-4 Series implements encryption processing, required in the financial field, based on that of the AE-4 Series. In addition, the RS-4 Series adds a coprocessor supporting stronger AES encryption and other security features. The final product versions will offer smart card MCU security level EAL5+ certification as defined under the latest version of the Common Criteria for IT Security Evaluation, an attestation of high-level security demanded by the target market.

STMicroelectronics Introduces Free Self-Test Software for STM32 MCU

STMicroelectronics has introduced a new software library for the recently-announced STM32 Flash microcontroller family, designed specifically to simplify the testing and securing end-product approval and compliance with the demands of the IEC 60335-1 standard when the MCU is used in household appliances. Since October 2007, IEC 60335-1 requires the software of MCU-based appliances to be evaluated according to its impact on overall consumer and application safety. When some of the fault detection relies on the microcontroller, the embedded code must contain self-test routines, and must be evaluated under the so-called Class B requirements for its ability to detect safety critical failures.

The new self-diagnostic software modules developed by ST for the STM32 family have been approved by the VDE (German Association for Electrical, Electronic & Information Technologies) testing and certification institute, which is recognized globally for its efforts. Now, when a manufacturer uses these modules in an application, the application will not need to be completely re-evaluated by VDE as part of the final product certification, thereby saving significant time for the appliance manufacturer. ST is the first semiconductor manufacturer to receive this certification for routines based on 32-bit MCUs.

The software library, with associated documentation, is available free of charge from ST on request. It includes a complete safe-boot sequence, plus self-diagnostic modules for the CPU, non-volatile memory, RAM, and the clock frequency. Transparent RAM tests are also carried out during run-time. In addition, the STM32 embeds safety-related hardware, including dual internal watchdogs and fail-safe clock circuitry, which simplifies certification by reducing the number of self-test routines actually required and decreasing the software overhead.

The new ST21F family will enable card manufacturers to react quickly and cost-effectively to the fast-changing needs of the mobile market, customizing applications late in the production process, at the card personalization stage, and addressing the requirements of multiple Mobile Network Operators with a single product. Supply chain risk and complexity can be reduced, as the silicon is not linked to a specific operator profile.

The ST21F384 is based on an enhanced 8/16-bit CPU core with 16 MByte linear addressing range, running typically at 21 MHz. It embeds 7 kBytes of user RAM, plus 384 kBytes of Flash memory, organized as 128-byte pages, with an erase capability similar to that of the EEPROM used in earlier devices in the secure family. Current consumption complies with 2G and 3G specifications to meet the requirements of (U)SIM applications. The microcontroller includes a hardware DES accelerator and a user-accessible CRC calculation block.

Samples of the ST21F384 are available now, with volume production starting this month. The ST21F384 is available as sawn or unsawn wafers, and in 6-contact (D17) and 8-contact (D95) RoHS-compliant modules, with contact assignment compatible with ISO 7816-2. In wafer form it is priced at $0.45 in quantities of 100,000 units.
