NFC-Reader and Discovery Kit from STMicroelectronics Gives Head-Start to Faster, More Efficient Contactless Applications, Free Discovery Kit available from Anglia
STMicroelectronics has combined its ST25R3911B NFC reader IC and STM32L476RE ultra-low-power microcontroller in a Discovery kit, ST25R3911B-DISCO, accelerating time to market for contactless applications that deliver superior communication range, speed, and energy efficiency with simplified design and reduced bill of materials. The new discovery board provides a reference for RF circuit layout, and with the included STM32 MCU software, can be quickly up and running as an HF reader or NFC initiator.
At the heart of ST’s new discovery kit is the ST25R3911B NFC reader IC that offers differentiating features to help simplify design-in, streamline manufacturing, and ensure superior user experiences.
Exceptional features for optimized power consumption include Dynamic Power Output, which avoids wasting energy by supplying the minimum needed to communicate with the target: a key advantage for portable devices and payment terminals. Capacitive wake-up allows detecting card presence while drawing less than 5µA in sleep mode to preserve battery energy in equipment such as hotel card-key readers. Inductive wake-up is also supported.
The ST25R3911B RF receiver is approximately five times more sensitive than typical devices, while up to 1.4W output power allows extended range without requiring an additional amplifier. Automatic Antenna Tuning (AAT) enables OEMs to fine-tune the antenna settings of end-user equipment efficiently on the production line. In addition, the ST25R3911B is the only device on the market that enables a single-chip solution for Very High Bit Rate (VHBR) operation, which boosts download speeds from 848kbit/s to 6.8Mbit/s, making it ideal for applications such as eGovernment systems including passports.
All major contactless and RFID standards are supported, including ISO 18092 (NFCIP-1) Active P2P, ISO14443A, ISO14443B, FeliCa™ and ISO 15693 contactless standards, allowing use in applications such as ticketing, asset tracking, device authentication, sensor-data collection, and access control.
The companion STM32L476RE ultra-low-power microcontroller on the Discovery kit board features the 80MHz ARM® Cortex®-M4 core with DSP extensions and floating-point unit, and achieves aggressive power savings through features such as smart architecture with FlexPowerControl, dynamic voltage scaling, and seven power-management modes with sub-mode options. An embedded memory protection unit enhances application security. The Discovery kit helps developers leverage the strengths of the MCU and reader IC together, and connects with the powerful STM32 ecosystem, including sample code, IP blocks, and expansion boards.
