SEC1110/SEC1210 Smart Card Bridge to USB and UART Interfaces - Protocol timers (Guard, Timeout, and CWT) General Description for EMV-defined timing parameters The SEC1110 and SEC1210 provide a single-chip Detection of an unresponsive card solution for a Smart Card bridge to USB and UART Activation/deactivation sequences interfaces. These bridges are controlled by an Cold/warm resets Monitoring for all EMV timing constraints enhanced 8051 micro controller and all chip peripher- 16-bit general purpose down counter for software als are accessed and controlled through the SFR or TM timing use XDATA register space.
