Contact smart card interface operates in 3V supply domain

On-demand services for premium content continue to drive the market for smart card interfaces in Set-Top Box (STB) applications. Through close collaboration with Cisco, the leading provider of secure technology solutions for digital pay-TV, the TDA8037 has achieved certification and validation, thus enabling secure access to premium media content.

As well as providing thermal and short circuit protections on all card contacts, the TDA8037 also integrates activation and deactivation sequences. These sequences can be triggered by software or hardware malfunctions, such as short-circuit, card take off, overheating or a significant drop in operating voltage.

Based on its various features, the TDA8037 also supports other demanding consumer applications besides pay-TV, such as identification, computer security and smart metering.

“Pay-TV today goes beyond simply paying for movies - it’s about offering new ways for consumers to experience and interact with valuable content. Achieving certification enables the TDA8037 to offer access to premium services via a set-top box quickly and securely; a feature that is strongly supported in the CE industry,” said Paul Hubmer, General Manager, Infrastructure & Consumer, NXP Semiconductors. “The ability of the TDA8037 to also operate at 3V is critical as we move to evermore power efficient and reliable systems.”

The TDA8037 is available now. Samples, as well as a full support package including the application notes, evaluation boards, evaluation software and further information, can be accessed on NXP's website.
