It combines a transponder reader interface with built-in configurable power saving, secure data storage, anti-collision control, and level shifting voltage regulator in one chip. It can be used in a variety of applications, such as automotive, industrial, healthcare systems, contactless access control security systems, transportation, and home automation.

AS3953B-BTWT Application Fields

AS3953B-BTWT can be used in applications such as security systems, contactless access control, secure data storage, automotive, industrial, healthcare systems, transportation and home automation. It is widely used in access control systems, such as employee badges, vehicle identification, or any access credential. The chip also can be used for automatic identification solutions, including receiving data from and writing data to RFID tags, as well as bus-level communication between reader and tag. It allows for secure storage of credentials, thus providing trusted access.

AS3953B-BTWT also provides a secure communication feature for security applications, such as cryptographic access control based on password or biometric data. It is also used in a variety of monitoring solutions, such as motion, contact, temperature or light sensors.

AS3953B-BTWT Working Principle

The AS3953B-BTWT is designed to reduce RF noise and interference through the use of a polyphase filter and a sigma-delta modulation technique to reduce RF energy transmission. The chip also incorporates a low-power level shifter voltage regulator that supports a low operating voltages of as low as 1V, making it ideal for battery-powered applications. The power saving feature allows the chip to enter and exit power-down mode in a matter of microseconds.

The chip also supports several industry standards, including ISO/IEC 14443, ISO/IEC 15693, and NFC Forum. It also supports several modular communication protocols, such as USB, I2C, and SPI. This enables the chip to be used in a variety of application scenarios.

The AS3953B-BTWT includes a configurable anti-collision algorithm that can be tailored to the particular application. This ensures that the communication protocol between the reader and the tag is reliable and secure. It also includes an AES-128 encryption engine that provides both secure read and write transactions.

In addition, the chip supports various authentication algorithms, such as three-pass handshake based on ISO/IEC 15693 and AES-128. This ensures secure data exchange between the reader and tag.

Overall, the AS3953B-BTWT is a highly integrated, low power and cost-effective solution for all your RFID, RF access, monitoring and other application requirements.
