The AS3956 dynamic tag enables a non-contact connection between any NFC reader, such as a sensor and a smartphone, via a master controller that supports NDEF data exchange protocols that meet NFC Forum requirements to ensure interoperability with any NFC handset, including Apple® iOS devices.
In order to ensure the reliability of AS3956, in the development process Ai Meisi Semiconductor and industrial applications and networking products manufacturers to engage in close interaction in the practical application of a comprehensive test to verify the chip in a series of harsh operating environment Under the superior performance and reliability.
Unlike the dynamic NFC tags currently available on the market today, the AS3956 is ideal for the following applications: • Extremely hot industrial and networking applications, including extreme temperature environments from -40 ° C to 125 ° C • Longer use Life products such as HVAC equipment, hearing aids and wireless sensors for applications such as roads, bridges and public facilities etc. AS3956's built-in EEPROM memory can perform at least 100,000 programming / erase cycles and data at 125 ° C. Year • Key mission products that require zero failure rates
The AS3956's capabilities provide designers with more flexibility in implementing NFC-based applications, including I2C and SPI interfaces for main microcontrollers and wide supply voltages of 1.65V to 5.5V.
In the basic operation, the AS3956 supports NFC communication with the reader as a separate Type 2 tag that conforms to the NFC Forum standard. In addition, the main controller can select two other data transfer modes: • Extended mode, The timed data transfer mechanism uses the standard Type 2 tag commands to minimize the software overhead required by the main controller. • Transparent mode can be implemented in accordance with EMVCo requirements ISO14443A Level 4 PICC Card Analog or Run Customization Protocol
The AS3956 has an energy harvesting capability that absorbs the energy generated by the NFC reader from the RF field and provides up to 5mA of current to the external device. The cost-effective and small footprint energy acquisition function replaces the standard wireless Charging module to help extend the life of the battery in a biometric smart card or to achieve a fully passive wireless sensor solution such as a smart insulin pen.
"Previous generations of generic NFC dynamic tags did not provide the reliability and flexibility required for many applications, while the AS3956 offers superior performance throughout the life of the product," said Giancarlo Cutrignelli, owner of the market for digital sensor products at Aymouth Semiconductor. The quality control process and the numerous validation tests carried out by Aymouth Semiconductor have enabled consumers to be confident that the AS3956 will function and maintain RF, interface and memory functions even in harsh or extreme environments.
The AIUS Semiconductor AS3956 offers a package with a thickness of only 0.3mm, a footprint of 1.8mm x 1.4mm, a small chip-scale package and a 3mm x 3mm MLPD package.
