Product Summary

The TDA8007BHL is a low cost card interface for dual smart card readers. Controlled through a parallel bus, it takes care of all ISO 7816, EMV and GSM11-11 requirements. It may be interfaced to the P0/P2 ports of a 80C51 family microcontroller, and be addressed as a memory through MOVX instructions. It may also be addressed on a non-multiplexed 8-bit data bus, by means of address registers AD0, AD1, AD2 and AD3. The applications of the TDA8007BHL include Multiple smart card readers for multiprotocol applications (EMV banking, digital pay TV, access control, etc.).
