TDA8000T - NXP

TDA8000T Smart card interface

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 co.
