The DEMO90121DA is a turnkey contactless door access example based on the RFID transceiver IC MLX90121. Once set up, it detects and reads ISO14443A cards and is capable through software configuration of lighting a red or a green LED.
As a stand alone application running on battery, the current consumption is optimized, taking into account an optimized response time. The form factor is minimized to demonstrate the high level of integration allowed by the MLX90121. The bill of material of DEMO90121DA targets a cost of 10$ per component set for 1000 modules.
Complete schematics, bill of material and layout are annexed to User Manual allowing a fast start for development. Source code of the firmware is based on the FW90121 library and is available on the CD ROM provided with the DEMO90121DA. This device is based on ISO14443A RFID standard, but the software library makes it is easy to adapt the firmware to use another ISO protocol.
Important note: The device is for demonstration purpose and has not been tested for compliance with FCC, ETSI or any other regulations. |
