ST25R210

概要

Delivering high-end performance in a compact 4 x 4 mm package, the multipurpose NFC reader enables the convenience of contactless interaction and features for various end applications. It is specifically optimized for consumer and industrial end products.

The ST25R210 product is a universal NFC device supporting NFC initiator, NFC target, NFC reader, and NFC card emulation operations. The high output power, up to 1.6 W, facilitates easy integration into applications with small antennas. The reader offers an excellent read range and features improved low-power card detection (LPCD), which increases the detection range in inductive wake-up mode. During this low-power wake-up mode, the system detects the approach or removal of tags. The IC includes an RC oscillator and a programmable timer to automatically scan for cards or other NFC-enabled devices, such as smartwatches or phones, when in wake-up mode.

The device high sensitivity, supported by ST noise suppression receiver (NSR) technology, ensures successful reads even in noisy environments.

The ST25R210 product integrates an advanced analog front-end (AFE) and a highly integrated data framing system for NFC-A/B (ISO14443A/B), including higher bit rates, NFC-F (Felica™), NFC-V (ISO15693) up to 212 kbps, and NFC-A/NFC-F for card emulation mode.

The ST25R210 device achieves long-range and low-power card detection by measuring the I and Q channels, which represent the real and imaginary parts of the antenna signal. This approach minimizes power consumption. It operates across a wide power supply range (2.7 to 5.5 V), an ambient temperature range (-40 to +105°C), and a wide peripheral I/O voltage range (1.65 to 5.5 V). With its combination of high RF output power, low-power modes, and wide supply range, the device is ideal for all NFC applications.

The ST25R210 device is available in a compact 4 x 4 mm 28-pin UQFPN28 package, enabling the integration of NFC technology into small devices.
