Abstract

A multi-mode IC is provided for operating in a first mode such as an ISO mode in accordance with International Standards Organization 7816 (ISO 7816) protocol, and a second, non-ISO mode, such as a USB mode in accordance with Universal Serial Bus (USB) protocol. The multi-mode IC is preferably in a smart card and includes a microprocessor and an external interface. The external interface comprises a voltage supply pad, a ground pad, a first set of pads for the first mode, and a second set of pads for the second mode. The first set of pads preferably include a reset pad, a clock pad an an input / output pad in accordance with the ISO 7816 protocol, and may also include a variable supply voltage pad in accordance with the ISO 7816 protocol. The IC further includes a mode configuration circuit for detecting a mode condition on one pad of the first set of pads, and configuring the IC in the ISO mode or the non-ISO mode depending on the result. Once the IC is configured ina particular mode, it will operate in only that mode until the next power-on reset sequence.

Description

technical field [0001] The present invention relates to information processing and storage, and more particularly to smart card systems. Background technique [0002] A smart card (SC) is a plastic card with a built-in integrated circuit (IC). The integrated circuit can be a logic circuit with corresponding memory, or a microcontroller with corresponding memory and software, or a microcontroller with corresponding memory and software coupled with a generic custom module. [0003] In order to apply the computing power of integrated circuits, smart cards use a full range of packaging processes. Package size (die size) from 1mm 2 to 10mm 2 wait. Package size is limited mechanically in line with the plastic texture of a smart card. The integrated circuit is attached to a lead frame (lead frame) lead frame, and a wire bonding method is used to weld the pins of the integrated chip to the lead frame lead frame. Potting and other reinforcement methods protect integrated chips ...
