Abstract: An integrated circuit for a smart card may include a transceiver for communicating with a host device and a Joint Test Action Group (JTAG) test controller for performing at least one test operation. Further, the integrated circuit may also include a processor for causing the JTAG test controller to initiate the at least one test operation based upon receiving at least one test request from the host device via the transceiver. More particularly, the processor may convert the at least one test request to JTAG data for the JTAG test controller. That is, the integrated circuit advantageously allows communications between the host device and the JTAG controller via a system bus, for example, without the need for a dedicated JTAG test access port (TAP) which is typically required for accessing JTAG controllers.

Abstract: An integrated circuit for a smart card may include a transceiver and a controller for cooperating with the transceiver to receive operating requests from a host device. The controller may perform smart card operations based upon respective operating requests. Moreover, the controller also may cooperate with the transceiver to receive at least one advance request from the host device to indicate that at least one operating request will follow. By way of example, the standby operation may include loading data in at least one buffer, which may be sent to the host device based upon receiving the at least one operating request. Other standby operations may include disabling data transmission to the host device, such as when the communications bus of the host device is preoccupied, and ceasing performing a current smart card operation to allow a higher priority smart card operation to be performed, for example.

Abstract: An integrated circuit for a smart card may include a universal serial bus (USB) transceiver for communicating with a USB host device, and a microprocessor connected to the USB transceiver and operable in a test mode and a user mode. When in the test mode, the microprocessor may perform a test operation based upon receiving at least one test vendor specific request (VSR) from the USB host device via the at least one USB transceiver. By way of example, the test operation may include scan testing the microprocessor's control logic, detecting a status of at least one buffer and communicating the status to the USB host device, writing test data to at least one designated buffer and sending the test data from the at least one designated buffer to the USB host device, and/or operating with reduced power.

Abstract: An integrated circuit (IC) may include at least one smart card memory for storing a set of default requests and at least one alternate request for each default request. The IC may further include a microprocessor connected to the at least one smart card memory for communicating with a host device using the default requests and alternate requests. The microprocessor may selectively switch between using the default requests and the alternate requests when communicating with the host device. As such, this provides a nullmoving targetnull which makes it difficult for would-be hackers to determine which requests are used for which smart card operations and, thus, to decipher and interfere with data communications.
