Atmel Corp. announced the availability of the Atmel AT73C260 IC, designed to bridge the host and USB UICC. The Atmel AT73C260 IC is for both existing and next-generation cell phone chipsets, supporting the latest SIM standard or the UICC Multimedia SIM.

The AT73C260 may be customized to accommodate one interface from many, utilized for data transfers between a variety of hosts, consisting but not limited to cellular phones, set-top-boxes, PCs, and the USB UICC.

Multimedia SIM is one particular new architecture that has been defined by ETSI (European Telecommunications Standards Institute) which answers the demands for more capacity, higher speeds and better security compared with existing SIM cards. Also known as the USB UICC (IC_USB1.0 based Universal Integrated Circuit Card), this architecture has been standardized as ETSI 102 600. The UICC accommodates web and multimedia cell phones, Digital Rights Management (DRM), multimedia stream decryption for Pay TV and can function as a mass storage device.

Atmel Marketing manager for power management and analog products, Michele Casetta says, "The Atmel AT73C260 IC is the industry's first to support this new ETSI standard and enable more secure, higher-speed data transfers from the SIM interface to the USB UICC." He adds, "The Atmel AT73C260 is also designed so it can fit into designs to complement existing cell phone chipsets, but with a smaller footprint to save board space and to lower the overall bill of materials."

The Atmel AT73C260 is currently the industry's first device to empower cellular phone manufactures with existing product designs which enable interface with the next-generation UICC Multimedia SIM standard. The sole requirement is to add the IC into an already-qualified chipset, to support the new USB UICC features in their current design. This new single-chip IC has multiple PHYs and two 70mA LDO voltage regulators.

Availability and pricing: The Atmel AT73C260 is currently available in production quantities, which comes in a QFN16 3x3 0.5mm pitch package. Pricing for the AT73C260 is $0.78 each in large volumes.
