GENERAL DESCRIPTION
The TDA8001 is a complete, low-cost analog interface
which can be positioned between an asynchronous smart
card (ISO 7816) and a microcontroller. It is directly
compatible with the new Datacom chip verifier.
The complete supply, protection and control functions are
realized with only a few external components, making this
product very attractive for consumer applications
(see Chapter “Application information”).
