STMicroelectronics' ST25R100 Near Field Communication (NFC) reader chip is unique in the industry. It combines advanced technical functions, stable and reliable communication connections, and low cost. It can be used in large-scale manufacturing of consumer electronics and industrial control equipment. Increase the value of contactless interactive features.
Measuring only 4mm x 4mm, the ST25R100 combines high performance, reliability and low power consumption to support mainstream contactless use cases. The small package is easy to integrate into end products such as printers, power tools, game consoles, home appliances, medical equipment and access control systems.
Sylvain Fidelis, Integrated Market Business Line Manager of STMicroelectronics, said: "For various products and equipment, contactless communication is a good way to achieve equipment interaction, such as verifying the authenticity of accessories, purchasing consumables, and monitoring usage. The ST25R100 product itself has more Highly cost-effective, our firmware ecosystem helps customers speed up application development, so it’s a cost-effective and easy-to-integrate data read solution.”
The ST25R100 supports advanced control functions needed to improve signal quality and power management efficiency, ensuring stable and reliable wireless connections and strong signals even in devices with limited space that can only accommodate small antennas. In addition, ST25R100 also adds an enhanced low-power card recognition function (LPCD), which can significantly extend the detection distance compared with existing new products and provide a good user experience.
ST25R100 integrates an advanced analog front end (AFE) and data framing system, supporting standard NFC specifications, NFC-A/B (ISO 14443A/B, maximum rate 106kb/s) and NFC-V (ISO 15693, maximum rate 53kbit) /s) reads data on the card.
The power supply voltage of the new reader chip and the peripheral I/O voltage are between 2.7V and 5.5V. Multiple working modes and power management functions can reduce the chip current to a minimum of 1µA, thus extending the life of battery-powered devices. . There is also a reset mode that consumes only 0.1µA.
Samples of the ST25R100 are now available in a 4mm x 4mm 24-pin TQFN compact package. The small package allows small-size devices to have contactless reading functions.
