A New Contactless Smartcard IC using an On-Chip Antenna and an Asynchronous Micro-controller

摘要

A new generation of Contactless Smartcard Chip is described. The Contactless Smartcard Chip 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 micro-controller. Beyond the Contactless smartcard application field, this new chip demonstrates that System-on-Chip integrating power reception and management, radio-frequency commu-nication and signal processing are feasible. The chip associates analog/digital parts as well as synchronous/asynchronous logics and has been fabricated in a CMOS 6 metal layers 25 μm technology from STMicroelectronics.
