TDA8000T Description
The TDA8000 is a plete, 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, tele and pay TV applications. The plete supply, protection and control functions are realized with only a few external ponents, which makes the TDA8000 very attractive for consumer applications.
TDA8000T Key Features
