This data sheet describes the functionality of the SLRC400 Integrated Circuit （IC）。 It includes the functional and electrical specifications and from a system and hardware viewpoint gives detailed information on how to design-in the device.

　　The SLRC400 is a member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz. This family of reader ICs provide： ? outstanding modulation and demodulation for passive contactless communication ? a wide range of methods and protocols The transmitter module Section 8.9 on page 24 can directly drive an antenna designed for proximity operating distance up to 100 mm without additional active circuitry. The receiver module provides a robust and efficient demodulation/decoding circuitry implementation for compatible transponder signals （see Section 8.10 on page 28）。 All layers of the ICODE1 and ISO/IEC 15693 protocols are supported. The receiver module provides a robust and efficient demodulation/decoding circuitry implementation for ICODE1 and ISO/IEC 15693 compatible transponder signals. The digital module manages ICODE1 and ISO/IEC 15693 framing and error detection （CRC）。 A parallel interface can be directly connected to any 8-bit microprocessor to ensure reader/terminal design flexibility.
