Mouser Stocks STMicroelectronics ST25R210 Aliro-Ready NFC Reader IC

Mouser announces ST25R210 availability

Mouser Electronics announced on August 26, 2026 that it is stocking the ST25R210 universal NFC reader from STMicroelectronics. The distributor describes the part as intended for cost-sensitive NFC applications and identifies it as Aliro-ready. The announcement is a distribution-availability event rather than the introduction of a new IC: ST’s datasheet was initially released in February 2026, and ST lists the device as an active product in volume production.

For access-control equipment developers, the listing matters because it adds a catalog distribution route for an NFC reader IC designed to sit between a host controller and a 13.56 MHz antenna. That architecture can support phone- and wearable-based tap credentials as well as compatible cards and tags, subject to the firmware, antenna, secure-element and system-level design decisions made by the reader manufacturer.

What the NFC front end supports

The ST25R210 is a multiprotocol device supporting NFC initiator, target, reader and card-emulation operations. In reader/writer use, ST specifies NFC-A and NFC-B operation up to 848 kbit/s, NFC-F/FeliCa up to 424 kbit/s, and NFC-V/ISO 15693 up to 212 kbit/s. For card emulation, it supports NFC-A at 106 kbit/s and NFC-F at 212 or 424 kbit/s.

ST specifies up to 1.6 W RF output power, low-power card detection, an SPI host interface up to 10 Mbit/s, and support for either one differential antenna or two independent single-ended antennas. The 4 x 4 mm, 28-pin package and -40°C to +105°C ambient operating specification may be especially relevant where reader electronics must fit constrained back boxes, lock escutcheons or industrial enclosures. Actual read performance will remain dependent on antenna geometry, enclosure materials, field tuning, nearby metal and the credential device.

Aliro context: readiness is not finished-reader certification

Aliro 1.0 was released by the Connectivity Standards Alliance on February 26, 2026. The specification defines a mobile access credential and communication approach for access readers and user devices, with NFC for tap-to-access alongside Bluetooth LE and Bluetooth LE plus ultra-wideband options for other access experiences. The Alliance positions the standard for commercial, residential, hospitality and university environments, among others.

ST includes the ST25R210 in its Aliro product portfolio and identifies the IC as Aliro-ready. That designation should not be read as proof that a completed reader, lock or access-control system is Aliro certified. Certification and interoperability are evaluated at the finished-product and implementation level; access OEMs will need to combine the RF IC with an appropriate controller, credential stack, security architecture, antenna design and validation program.

Design and integration considerations

The part’s low-power inductive card-detection function can allow a host system to detect the approach or removal of a credential while using a lower-power wake-up mode. ST also documents dynamic power output, active wave shaping, noise-suppression reception and antenna-tuning provisions. These functions can be useful in reader designs that must manage RF field behavior and tolerate electrically noisy installations, but they do not eliminate the need for on-door RF testing.

Procurement and engineering teams should also treat the IC as one component in a reader bill of materials, not as a complete access-control module. Evaluation requires matching the package, power rails, external antenna network, controller software and desired credential technologies to the intended enclosure and installation conditions. Mouser notes that ST’s X-NUCLEO-NFC13A1 expansion board can be used with a compatible STM32 Nucleo board for testing, offering a potential early evaluation route before a custom reader board is committed.

A component option as Aliro deployment begins

The practical value of the ST25R210 for security integrators will emerge through the reader products built around it, rather than through the IC alone. Still, availability through Mouser provides a sourcing option for OEMs and design partners investigating tap-based credentials as part of an Aliro-oriented product roadmap.

Teams planning deployments should ask finished-reader suppliers for the exact credential technologies supported, the status of any Aliro certification, mobile-wallet compatibility, controller-platform requirements and lifecycle commitments. ST’s product page lists the ST25R210 under its 10-year longevity program, a consideration for access-control hardware that may remain installed for many years.
