- Power Supply: Operates at 3.3V (typical).
- Antenna Control: Includes TX/RX drivers and analog front-end for antenna tuning.
- Security: Supports encryption (e.g., MIFARE authentication).
- GPIOs: Configurable for LED, buzzer, or other I/O functions.
Pins include VDD (power), GND, SPI (SCK, MOSI, MISO, NSS), antenna (TX1/TX2, RX), and interrupt (IRQ).

The FM1701 is a highly integrated RFID reader chip, primarily used in:
1. Access Control Systems – For secure entry management.
2. Payment Terminals – Supporting contactless transactions (e.g., NFC payments).
3. Public Transportation – Smart cards for fare collection.
4. Identity Verification – Employee/student ID cards.
5. IoT & Smart Devices – Enabling RFID/NFC communication.
6. Inventory Management – Tracking goods via RFID tags.
It supports ISO/IEC 14443 Type A/B and MIFARE protocols, making it versatile for secure, short-range wireless applications.

The FM1701 is typically available in a TSSOP32 (Thin Shrink Small Outline Package) package. This compact, surface-mount package has 32 pins and is commonly used for RFID and NFC reader ICs due to its small footprint and reliable performance. Suitable for high-density PCB designs.
