4164E–SCR–02/04

Smart Card Interface Block (SCIB)

Introduction

The SCIB provides all signals to directly interface a smart card. Compliance with the

ISO7816, EMV’2000, GSM and WHQL standards has been certified.

Both synchronous (e.g. memory card) and asynchronous smart cards (e.g. micropro-

cessor card) are supported. The component supplies the different voltages requested by

the smart card. The power-off sequence is directly managed by the SCIB.

The card presence switch of the smart card connector is used to detect card insertion or

card removal. In case of card removal, the SCIB de-activates the smart card using the

de-activation sequence. An interrupt can be generated when a card is inserted or

removed.

Any malfunction is reported to the microcontroller (interrupt + control register).

The different operating modes are configured by internal registers.
