Abstract

For proper communication with various types of IC-Card, multiple IC-Card interface complying with the IC-Card standard (ISO7816) is embedded and realized as a peripheral on the 32-bit RISC based system-on-a-chip. It provides the generation of either 3.3V or 5V power supply for the operation of the inserted IC-Card as well. IC-Card interface is divided into an analog front-end (AFE) and a digital back-end (DBE). The embedded DC-DC converters suitable for driving IC-Cards are incorporated in the AFE. The chip design for multiple IC-Card interface is implemented on a standard 0.35${\mu}{\textrm}{m}$ triple-metal double-poly CMOS process and is packaged in a 352-pin plastic ball grid array (PBGA). The total gate count is about 400,000, excluding the internal memory. Die area is 7890${\mu}{\textrm}{m}$ $\times$ 7890${\mu}{\textrm}{m}$.
