GENERAL DESCRIPTION
The 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”).
