CF45538NSRG4 Application Field and Working Principle

RFID

CF45538NSRG4 is a 13.56 MHz HF RFID Transponder IC. It is characterized with low power consumption, high security, fast data transmission, small size and good anti-interference for RFID eavesdropping. This IC is targeted at indoor environment and on-metal applications, and no special installation requirement or tools are needed for installation.

The RF communication field between the CF45538NSRG4 and the reader is shown below. The antenna first radiates a continuous frequency electromagnetic field at 13.56MHz, and the IC is powered by backscattering in the field. After the IC is powered, it will transmit the encrypted UID and user data by backscattering.

RF Access Control

CF45538NSRG4 supports two types of access control protocols: the first is the basic ISO/IEC 14443 Type A protocol, and the second is the Mifare protocol, supporting the Mifare Classic and Mifare Ultralight Cards. The CF45538NSRG4 main security feature includes an anti-tapping, anti-collision, and authentication functions in addition to its 64 bit UID and 32 bit password system. After the IC is powered, it is able to identify the reader and authenticate its commands from the reader. Once the authentication is successful, the user data stored in the card can be read or modified.

Monitoring ICs

CF45538NSRG4 also supports external sensor integration, such as temperature, pressure, and humidity sensors. The IC can periodically monitor the external environment and send a signal to a reader when a preset threshold is exceeded. This feature of the IC provides more powerful function for smart monitoring system. This feature allows the IC to be used in various applications such as closed space monitoring and inventory.

The CF45538NSRG4 IC offers consistent performance, low power consumption, and high security, making it an ideal choice for embedded applications in a variety of smart applications, such as access control, inventory and asset tracking, as well as smart environmental monitoring.
