CR95HF-VMD5T - 13.56MHz Multi-Protocol RFID Reader IC | STMicroelectronics
MPN: CR95HF-VMD5T ✓ فعالCR95HF-VMD5T نمای کلی
An RFID reader IC is the active analog and digital subsystem that generates the 13.56 MHz carrier, conditions reader signals through an antenna interface, detects tag responses, and transfers decoded data to a host processor. The CR95HF belongs to the contactless-communications and NFC/RFID transceiver hierarchy, combining RF analog front-end functions, protocol handling, and serial host connectivity in one surface-mount device.
The device provides multi-protocol coverage for ISO/IEC 14443 Type A and B, ISO/IEC 15693 with single or double subcarrier operation, and ISO/IEC 18092 communication. Its NFC capabilities include detection, reading, and writing for NFC Forum Type 1, 2, 3, and 4 tags. These features make it useful for systems that must handle more than one contactless-tag family without relying on separate reader electronics.
Communication with a host is available through SPI and UART interfaces, allowing integration with embedded processors and controllers. The listed operating supply range is 2.7 V to 5.5 V, which supports designs using common low-voltage digital rails. The package is a 32-pin VFQFN with an exposed pad, requiring careful land-pattern, thermal-pad, and high-frequency layout implementation.
Typical uses include access-control terminals, payment and ticketing readers, asset-tracking equipment, industrial identification systems, consumer NFC readers, and embedded contactless interfaces. The 13.56 MHz operating frequency and protocol support align the part with short-range RFID and NFC applications where a reader must communicate with passive tags or cards.
Designers should follow the manufacturer’s antenna, matching, decoupling, and exposed-pad guidance. Because this is a high-frequency RF device, trace geometry, ground continuity, supply filtering, antenna geometry, and exposure to nearby metal or noisy sources can materially affect read range and reliability. Validate the complete reader path with representative tags rather than relying only on digital communication tests.

کاربردهای معمول
CR95HF-VMD5T مناسب است برای 6 کاربردs: Access-Control Reader, Payment and Ticketing Terminal, Asset-Tracking Reader, Consumer NFC Interface, Industrial Identification Gateway, Contactless Reader Development Platform.
Access-Control Reader
The CR95HF-VMD5T fits 13.56 MHz access-control readers that must handle contactless credentials across ISO/IEC 14443 and NFC tag families. Its 2.7 V to 5.5 V operating range can align with common embedded supply rails, while SPI or UART provides a path to the controller. The design still needs an antenna, matching network, firmware, and credential-management layer. Validate read distance with the intended cards and account for enclosure, metal, and human-body detuning.
پیشنهادی
Payment and Ticketing Terminal
For payment and ticketing terminals, the CR95HF-VMD5T provides a 13.56 MHz contactless reader core and supports the listed ISO/IEC and NFC Forum tag operations. SPI can suit an embedded processor, while UART can simplify connection to a compact controller or service interface. The part does not provide the complete secure payment product; firmware, host cryptography, antennas, and system certification remain application responsibilities. Benchmark read latency and reliability with the actual credential population and target enclosure.
پیشنهادی
Asset-Tracking Reader
The CR95HF-VMD5T is appropriate for industrial asset-tracking readers using passive 13.56 MHz tags. Multi-protocol support can simplify deployments that include ISO/IEC 15693 tags alongside ISO/IEC 14443 credentials. The 32-VFQFN exposed-pad package requires careful PCB construction and thermal-pad assembly, while the RF path requires a correctly designed antenna and matching network. Read range is system-dependent and should be characterized with the selected tag, housing, mounting distance, and operating environment.
پیشنهادی
Consumer NFC Interface
A consumer NFC reader can use the CR95HF-VMD5T when the product needs detection, reading, and writing for NFC Forum Type 1 through Type 4 tags. The device’s 13.56 MHz operating frequency aligns with common contactless phone and tag ecosystems, while SPI or UART provides host connectivity. Firmware must manage tag selection, protocol timing, user feedback, and security requirements. The final antenna must be tuned around the enclosure because plastic, metal, cables, and nearby loads can substantially change coupling and usable range.
پیشنهادی
Industrial Identification Gateway
The CR95HF-VMD5T can serve as the contactless reader stage in an industrial identification gateway. Its 2.7 V to 5.5 V supply range supports integration into embedded equipment, and its protocol coverage provides flexibility across ISO/IEC 14443, ISO/IEC 15693, and ISO/IEC 18092 devices. The gateway must provide antenna control, RF calibration, host communication, diagnostics, and production provisioning. Use the exposed-pad footprint as specified by STMicroelectronics and verify thermal performance under the enclosure’s worst-case ambient condition.
پیشنهادی
Contactless Reader Development Platform
The CR95HF-VMD5T is useful in a development platform when engineers need to prototype 13.56 MHz RFID and NFC reader behavior across several protocols. SPI and UART interfaces allow host-control experiments, firmware development, and antenna characterization without building the RF front end from discrete blocks. The developer should use the manufacturer reference design and exposed-pad layout guidance, then measure receive margin, field strength, tag detection time, and behavior with the intended tag population. This makes the device suitable for both firmware and hardware bring-up.

یادداشت‌های طراحی
Treat the exposed pad as a thermal and electrical land feature, not as an optional package detail. Follow the STMicroelectronics land pattern and paste recommendation exactly, including exposed-pad vias and solder mask clearance. The supplied sources identify a 32-VFQFN with exposed pad but do not provide the full footprint drawing, so use the manufacturer package data before releasing artwork rather than copying a generic QFN footprint.
Place the RF transceiver, matching components, antenna feed, and grounding structure as a tightly controlled RF subsystem. Minimize discontinuities and long return paths, keep supply filtering close to the device pins, and follow the manufacturer antenna and layout guidance. For 13.56 MHz designs, enclosure plastics, nearby metal, cable loading, and human-body proximity can alter matching and read range, so validate the assembled product rather than only the bare PCB.
Confirm whether the selected host uses SPI or UART and route that interface according to the datasheet timing and signal-level requirements. The supplied data confirms both interfaces but does not include complete pin functions, timing tables, or absolute maximum ratings. Before firmware freeze, verify wake-up, reset, clock, interrupt, and serial behavior with the exact package pinout and validate interface levels against the host device.
Do not treat protocol compatibility as equivalent to guaranteed interoperability. Confirm the tag type, operating mode, memory behavior, security requirements, and regulatory environment expected by the end product. Also verify read/write permissions and antenna performance with representative samples. The CR95HF supports several ISO/IEC and NFC Forum tag families, but a successful protocol connection does not guarantee a specified read distance or user experience inside the final enclosure.
