CST56I01 (Sim/Uim Card Interface)

▶ Overview
Sniper-II는 ISO7816-3(Identification Card)standard의 Asynchronous T0,T1을 지원한다.Parallel Data,Address, Command을 이용하여 Host와 Interface한다. Smart Card의 Control은 Software의 관여없이 Hardware(Smart Card Control Block)가 Card Insertion, Auto Activation Sequence, De-Activation Sequence(Card Removal/Finish), Data 처리를 효과적으로 Control하고, 모든 처리는 Interrupt Status을 이용하여 Interrupt Routine에서 처리하게 Design되어 있다. 따라서 SIM, UIM등의 Application에 적합하다.

▶ Features

◆ 32 SOP/32 LQFP
◆ Up to 64Mhz operation
◆ 2 channel ISO/IEC 7816-3 Aysnc. Communication Controller(ACC)
    - Data length : 8 bits
    - Parity bit generation and checking
    - Transmission of error signal (parity error) in receive mode
    - Error signal detection and automatic data retransmission in transmit mode
    - Direct convection and inverse convection both supported
    - Built-in baud rate generator allows any bits rate selected
    - Half duplex communication
    - Each channel have 8 interrupt source
      * De-bounce check complete interrupt
      * Interval interrupt between the leading edges of two consecutive characters
      * First ATR sequence not assert interrupt within 4000 smart card clock
      * Transmit buffer empty interrupt
      * Transmit parity error retry time our interrupt
      * Receive buffer full interrupt
      * Receive parity error retry time out interrupt
      * Auto de-activation complete interrupt
