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 emitter/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 that system-on-chip integrating power reception and management, radio-frequency communication, and signal processing is feasible. It associates analog/digital parts as well as synchronous/asynchronous logics and has been fabricated in a CMOS six metal layers 0.25-μm technology from STMicroelectronics
