Introduction

SL3S1205FUD/HAZ is a product of STMicroelectronics, a leading provider of RFID, RF Access, Monitoring ICs (Integrated Circuits). Specifically, it is a 125kHz contactless reader IC, ideal for applications for contactless access control, ID for user, animal, and asset identification, providing a cost-effective solution. This article will explain the application field and working principle of SL3S1205FUD/HAZ.

Application Field

The SL3S1205FUD/HAZ is suitable for access control, ID for user, animal, and asset identification, providing a cost-effective solution. The product is typically used in automatic gate opener, car locks, and electronic bathrooms, etc. It is also ideal for smart home and building automation, industrial automation, secure contactless transaction, health care, and retail application.

The SL3S1205FUD/HAZ can be applied in the following fields, such as automatic parking systems, connection to industry 4.0 machines, automatic payment systems, automatic tickets for public transportation, etc. The product can also be used for RFID-based asset tracking, livestock identification, access control, and biometric authentication. SL3S1205FUD/HAZ also supports integration into existing systems for remote access and secure transactions, enabling products to be used in any application where online authentication is required.

Working Principle

The SL3S1205FUD/HAZ operates at a frequency of 125kHz and has a low-noise amplifier, an 8-bit ALOHA RF data acquisition module, a wide-band RF transmitter, and a high-gain receiver with an improved signal-to-noise ratio. It works by using the 35-bit Manchester code standard, and uses a unique 16-bit field while a Manchester-coded byte is being sent.

Moreover, the SL3S1205FUD/HAZ utilizes a secure encryption scheme to provide an additional layer of protection. It utilizes a 16-bit field containing the Hall cover and data reference to provide a unique ID to authenticate. It also uses digital signal processing technology to reduce the influence of interference, enabling reliable signal transmission.

The card SL3S1205FUD/HAZ is supplied with a Mifare 64-bit memory. It includes an additional 8-bit checksum to make sure that the data is intact and can only be modified internally by STMicroelectronics. It also allows for anti-piracy measures in contactless payment operations, enabling secure transactions.

Conclusion

In conclusion, SL3S1205FUD/HAZ is an integrated circuit suitable for use in RFID, RF Access, Monitoring ICs. It is preferred for its application fields and working principles, such as automatic parking systems, connection to industry 4.0 machines, automatic payment systems, and livestock identification. It can be used for access control and biometric authentication, as well as secure contactless transaction. It utilizes a secure encryption scheme and digital signal processing technology to provide reliable signal transmission.
