Infineon Technologies has unveiled its new product family of security MCUs specifically designed for use in SIM cards.

Offering overall memory capacities of 256-512Kbytes, the SLE 76 family targets the fast-growing high-volume segment of mid-range to high-end SIM cards. The SLE 76 family further advances download execution speeds and improves multi-application capabilities for SIM cards.

At present, the SLE 76 family includes six members with more memory configurations under development. The MCUs cover memory requirements for SIM cards ranging from capacities of 64-256Kbytes of EEPROM available as flash memory and ROM with RAM sizes varying between 6Kbyte and 12Kbytes.

Flash products are configurable in code and data sections with a 4Kbyte granularity and include a powerful bootloader to securely download 512Kbyte of flash content in less than 10s.

The full 16bit architecture allows for the linear addressing of 16Mbyte of virtual memory and independently handles performance optimization by automatic power limitation and highest NVM reliability.

In addition to high performance and ease-of-use, the SLE 76 features high flexibility for current and future applications. The hardware architecture is designed for quick integration of new interfaces, memory technologies and other peripherals. This flexible architecture enables card manufacturers to re-use their existing OS and deploy cards with additional features.

To ease transition from existing applications based on Infineon's SLE 50PE and SLE 66PE 16bit security MCU families, the development tools and instruction set are only different in new features of the SLE 76 family. Training is also available on request.

All SLE 76 devices are available in several package variations including wirebond, flip-chip and SMD.
