Introduction

AI Translation

FM17522 is a highly integrated contactless reader/writer chip operating at 13.56 MHz, supporting contactless reader/writer mode compliant with the ISO/IEC 14443 Type A protocol. It also provides a low-power external card detection function, making it ideal for battery-powered reader/writer devices that require low-power operation and real-time handling of external cards entering the RF field at any time. The FM17522 features low voltage, low power consumption, strong drive capability, and multi-interface support. It is suitable for contactless reader/writer applications with low-power, low-voltage, and low-cost requirements.
