7. SMART CARD READER INTERFACE (SCR)
7.1 Features
Winbond's implementation of Smart Card Reader interface is based on ISO/IEC 7816-3 standard and
fully compliant with PC/SC Specifications 1.0. Except for pins specified in ISO/IEC 7816-3,
W83637HF's SCI also includes SCPSNT (Smart Card Present) monitoring status of card
insertion/extraction, SCLED (Smart Card traffic LED display) which is active high when host is
accessing information to/from card, and two general-purpose I/O pins SCC4 and SCC8 (only available
in W83637HF) for users to design application-specific functions.
Register file (control and status registers) of Winbond's Smart Card interface is designed in an UART-
like structure so that users with previous UART experience should have no trouble to implement
Winbond's SCI applications.
Power consumption is minimized by sophisticated device's operation scheme.
