PN5120A0HN1/C1,151

• Application Field
  The PN5120A0HN1/C1 is suitable for a wide range of applications. It is capable of providing power, modulation and demodulation, protocol stack and application for contactless smart card and data transfer. It can be used in contactless smart card reader/writers, NFC-enabled mobile phones, and consumer electronics. The PN5120A0HN1/C1 enables secure NFC communication such as payment, access control, contactless ticketing, authentication, etc. It supports most popular communication protocols such as SPI, I2C, UART, and HCI.
  
  
• Working Principle
  The PN5120A0HN1/C1 operates by using a passive near field communication (NFC) RFID transponder, which is used to transfer data between two points. The transponder consists of an integrated circuit (IC) that contains its own power source, modulation and demodulation, protocol stack, and application. When the transponder is placed close to an NFC reader, the electromagnetic energy emitted by the reader is picked up by the transponder’s antenna, and the IC powers up and communicates with the reader, enabling the secure transfer of data.
  
  
• Features
  The PN5120A0HN1/C1 has numerous features. It offers a high level of integration, cost saving, and extremely low power consumption. It includes an antenna detection logic, which can detect the presence of an external antenna. It is also capable of detecting and blocking malicious NFC traffic, including Man In The Middle (MITM). Additionally, it supports various communication protocols such as SPI, I2C, UART, and HCI, and is also compatible with most industry standard interface protocols such as ISO 14443 Type A/B and ISO 15693.
