A new Contactless Smart Card IC using an on-chip antenna and an asynchronous microcontroller

This paper describes a new generation of Contactless Smart Card Chip which integrates an on-chip coil connected to a power reception system and an emi tter/receiver module compatible with the ISO 14443 standard, together with an asynchronous quasi-delay insensitive (QDI) 8-bit microcontroller, Beyond the Contactless Smart Card application field, this new chip demonstrates t hat system-on-chip integrating power reception and management, radio-freque ncy communication, and signal processing is feasible. It associates analog/ digital parts as well as synchronous/asynchronous logics and has been fabri cated in a CMOS six metal layers 0.25-mum technology from STMicroelectronic s.
