Introduction
The FM1702/FM1712/FM1715/FM1722/FM1725 is highly integrated reader IC for contactless communication at 13.56MHz. It supports all layers of the ISO14443 includingthe typeAand type Bcommunication scheme.

Highly integrated analog circuitry to demodulate and decode card response Buffered output drivers to connect an antenna with minimum number of external components Proximity operating distance (up to 100 mm) Supports :
•FM1702: ISO14443 type A
•FM1712/ FM1715: ISO14443 type A & B
•FM1722/FM1725: ISO 14443 A&B, ISO15693
•Supports contactless communication with higher baudrates up to 424 kbaud
•Crypto1 and secure non-volatile internal key memory
•Pin-compatible to the MF RC500, MF RC530 and the SL RC400
•Parallel μ-Processor interface with internal address latch and IRQ line
•SPI compatible interface
•Flexible interrupt handling
•Automatic detection of parallel μ-Processor interface type
•Comfortable 64 byte send and receive FIFO-buffer
•Hard reset with low power function
•Power down mode per software
•Programmable timer
• Unique serial number
•User programmable start-up configuration
•Bit- and byte-oriented framing
•Independent power supply pins for digital, analog and transmitter part
•Internal oscillator buffer to connect 13.56 MHz quartz, optimized for low phase jitter
