MICROCHIP SEC1210-I/PV-UR2

The SEC1110 and SEC1210 provide a single-chip solution for a Smart Card bridge to USB 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.

• Smart Card
  • The SEC1110 provides one Smart Card interface and the SEC1210 provides two
