摘要: This paper describes a new generation of contactless smart card chip which integrates an on-chip coil connected to power reception system and emitter/receiver module compatible with the ISO 14443 standard, together asynchronous quasi-delay insensitive (QDI) 8-bit microcontroller. Beyond application field, this demonstrates that system-on-chip integrating management, radio-frequency communication, signal processing is feasible. It associates analog/digital parts as well synchronous/asynchronous logics has been fabricated in CMOS six metal layers 0.25-/spl mu/m technology from STMicroelectronics.
