The SEC1100 provide a single-chip solution for a Smart Card bridge to USB, SPI, and UART interfaces. These bridges are controlled by an enhanced 8051 micro controller and all chip peripherals are accessed and controlled through the SFR or XDATA register space. SMSC’s TrustSpanTM Technology enables digital systems to securely communicate, process, move and store information on system boards, across networks and through the cloud.The SEC1100 provides one Smart Card interface Fully compliant with ISO/IEC 7816, EMV, and PC/SC standards Versatile ETU rate generation, supporting current and proposed rates (up to 826 Kbps) Full support of both T=0 and T=1 protocols Full-packet FIFO (259 bytes), for transmit and receive Half-duplex operation (no software intervention required between transmit and receive phases of exchange) Loose real-time response required of software (approximately 180 ms) Dynamically programmable FIFO threshold with byte granularity Time-out FIFO flush interrupt, independent of threshold Programmable Smart Card clock frequency UART-like register file structure, expanded to 4 banks of 16 registers Supports Class A, Class B, Class C, or Class AB Fully compliant ESD protection on card pins Full-speed (12 Mbps) USB operation compliant to the USB 2.0 Specification 5.0 V tolerance on user accessible IO pins Self-clocking internal oscillator, no external crystal required 3.0 V - 5.5 V supply input
