| DEMO90121LR RFID Long Range Demo User Manual Output power of 1Watt Supports ISO15693 international standard RS232 communication BOM cost target Application Examples Asset tracking Library’s book inventory control Bicycle rental checkout Ordering Information Part No. DEMO90121LR Description Long Range Demonstrator 1 Scope The DEMO90121LR is a turnkey contactless long range reader example based on the RFID transceiver IC MLX90121. Once set up, it can inventory and access ISO15693 compliant tags and cards by sending corresponding commands. The DEMO90121LR is connected to a computer through its RS232 serial interface. The Melexis user interface program UT121 can be used for easy and fast evaluation of the demonstrator. The form factor is minimized to demonstrate the high level of integration allowed by the MLX90121. The bill of material for DEMO90121LR targets a cost of per component set for 1000 modules. Complete schematics, bill of material and layout are annexed to this document allowing a fast start for development work. Source code of the firmware is based on the FW90121 library and is available on the CD ROM provided with the DEMO90121LR. This device is based on ISO15693 RFID standard, maximizing the operating distance. This document includes fast start instructions, describes the performance of the demo and explains its hardware and software. The demo and documentation are a starting point for building customized long range reader systems by adapting the functions and performance to meet specific requirements. 2 Related Melexis product MLX90121 13.56MHz transceiver Important note The device is for demonstration purpose and has not been tested for compliance with FCC, ETSI or any other regulations.
