Introduction

FM17610 is a highly integrated contactless communication IC operating at 13.56 MHz with low-power card detection capability. It supports reader/writer mode compliant with ISO/IEC 14443 Type A and Type B protocols. The IC features low voltage, low power consumption, single-ended driving, and multi-protocol support, making it suitable for contactless reader applications with strict requirements on power consumption, voltage, and cost. Its low-power card detection function is particularly well-suited for battery-powered devices that require low power consumption and real-time detection of cards entering the field.
