EM Microelectronic, an electronic systems company of the Swatch Group, unveiled a family of flash memory-based smart card ICs designed for use in SIM cards for low-end mobile telephony.

According to the press release, memory flexibility is a key advantage of the EMTG30 and EMTG56, which contains 31KB and 57KB, respectively, of pure flash memory. These two devices also have a memory architecture that is 100 percent re-programmable. "The flexibility of using flash memory opens up a new field of applications, where smart cards can be truly 'smart,' allowing them to be fully reprogrammable in the field, adapting to changing applications, operating systems and user requirements," said Mougahed Darwish, president of the management board of EM Microelectronic. "For the manufacturer, it means that one card design can be used for a wide variety of applications, and inventories of cards can be quickly personalized at low cost to meet market demands."

Compatible with the ISO7816-3 IC card (smart card) specification, the EMTG30/56 feature a high-performance 8-bit market standard 8051 microcontroller (MCU) core that is implemented in hardware, allowing it to process instructions four times faster per clock cycle than typical microcode-based 8051 core designs. An internal tamper-proof clock operates at up to 30MHz and provides better security than designs that require an external clock. Security is also enhanced by the EMTG30/56's built-in analog, hardware-protected memory partitioning and tamper notification.

The EMTG30's flash memory structure is only one section of 31KB General Purpose NVM organized in 248 pages of 128 Byte. For the EMTG56, the GPNVM is organized in 448 pages of 128 Byte. They have a minimum guaranteed endurance of 100k cycles.

In addition, EM Micro said, the EMTG30/56's flexible memory architecture enables low cost smart cards to interoperate with equipment from different service providers and regional standards, making them suitable for banking and communications in developing countries worldwide.

The 8051 MCU core is a proven, robust and widely supported architecture, allowing code re-usability and faster development. The EMTG30/56 are supported by various development tools, including a compiler, link editor, code and data download, and Emulation platform that is fully integrated with the Keil uVision2 development environment.

The EMTG30/56 smart card ICs are available as backlapped and distressed 8-inch wafers down to 180?m thickness, as sawn wafers on frame, and in packaged 6-pin module form.
