Smart Card Interface 24-Pin QFN T/R

The SEC1210 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. TrustSpanTM Technology enables digital systems to securely communicate, process, move and store information on system boards, across networks and through the cloud.
