  1. 2008/05/27 SLRC400 - I·CODE Reader IC

General Description
The SL RC400 is member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz.
This new reader IC family utilises an outstanding modulation and demodulation concept completely integrated for all kinds of passive contactless communication methods and protocols at 13.56 MHz.
The SL RC400 supports all layers of I*CODE1 and ISO 15693.
The internal transmitter part is able to drive an antenna designed for proximity operating distance (up to 100 mm) directly without additional active circuitry.
The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from I*CODE1 and ISO 15693 compatible transponders.
The digital part handles I*CODE1 and ISO 15693 framing and error detection (CRC).
A comfortable parallel interface which can be directly connected to any 8-bit μ-Processor gives high flexibility for the reader/terminal design.

* Highly integrated analog circuitry to demodulate and decode label response
