Product Summary

The FM1702NL is a contactless reader IC based on ISO14443. It takes 0.6μm CMOS EEPROM processing technology. The device supports all layers of ISO14443 typeA and ISO15693 on 13.56MHz. M1 and SH security arithmetic are both supported. The FM1702NL internal highly integrated analog circuitry for modulating/demodulating and thus it can work with the least peripheral circuitry. It supports six types of μ-processor interface. The FM1702NL is optimized for use in public transport, variously charging payment card and comparable applications using contactless communication.

Parametrics

FM1702NL absolute maximum ratings: (1)Tamb.abs Ambient or storage temperature range: -40 to 150℃; (2)DVDD AVDD TVDD DC supply voltages: -0.5 to 6V; (3)Vin.abs Absolute voltage on any digital pin to DVSS: -0.5 to DVDD+0.5V; (4)VRX.abs Absolute voltage on RX pin to AVSS: -0.5 to AVDD+0.5V.

Features

FM1702NL features: (1)Highly integrated analog circuitry for modulate/demodulate, only require the least peripheral circuitry; (2)Proximity operating distance(up to 100mm, depend on the antenna); (3)Supports ISO14443 typeA protocol; (4)Supports ISO15693 protocol; (5)512 byte EEPROM; (6)Support M1 and SH security arithmetic; (7)Support six types of μ-processor interface; (8)64 byte FIFO; (9)Two voltage operation modes of digital module: TTL/CMOS; (10)Support standby/soft power down mode.
