Introduction

AI Translation

The ST25R100 multi-function NFC transceiver in a compact 4x4 mm package delivers high-end performance, bringing the convenience and capabilities of contactless interaction to a wide range of end applications. It is specifically optimized for consumer and industrial terminal products. The ST25R100 supports NFC reader mode, and its high output power makes it easy to integrate into applications using small antennas. The reader offers excellent read range and features improved Low Power Card Detection (LPCD) with extended detection range in inductive wake-up mode. In low-power wake-up mode, the system can detect tag approach or removal. The IC incorporates an RC oscillator and a programmable timer to automatically scan for cards or other NFC-enabled devices — such as smartwatches or mobile phones — in wake-up mode. The ST25R100's high sensitivity is achieved through STMicroelectronics' Noise Suppression Receiver (NSR) technology, enabling successful reads even in noisy environments. The device includes an advanced AFE and a highly integrated data framing system for reading NFC-A/B (ISO 14443A/B) and NFC-V (ISO 15693) cards. The AFE's transparent mode can be used to implement additional custom protocols in reader mode. The ST25R100 is housed in a compact 4x4 mm 24-pin TQFN package, enabling NFC integration into small form-factor devices. The ST25R100 is designed to operate over a wide supply voltage range (2.7 to 5.5 V) and a wide peripheral IO voltage range (2.7 to 5.5 V), with an ambient temperature range of -25°C to +85°C.
