DescriptionThe TDA8000 is a complete, low-cost analog interface which can be positioned between a smart card or a memory card (ISO 7816) and a microcontroller. It is approved for banking, telecom and pay TV applications.
The complete supply, protection and control functions are realized with only a few external components, which makes the TDA8000 very attractive for consumer applications. Application suggestions and support is available on request (see examples in Chapter "Application information").
