The device integrates an ARM Cortex-M3 microcontroller core, NFC analog front end, and NCI-compliant host interface in a 64-ball VFBGA (Very Fine-pitch Ball Grid Array) package, designed for mobile devices and NFC-compliant systems. An NFC controller is a contactless-communication transceiver that powers and communicates with NFC tags, smart cards, and peer devices over a short-range 13.56 MHz inductive link. The PN7160A1EV sits between the host application processor (typically running Android, Linux, or Windows) and the NFC antenna, handling modulation, demodulation, framing, anti-collision, and protocol stack execution. Within the broader taxonomy, it belongs to: NFC controller -> RFID reader IC -> RF transceiver -> wireless IC -> semiconductor. Key features include support for all major NFC standards (NFCIP-1, NFCIP-2, ISO/IEC 14443 A/B, ISO/IEC 15693, FeliCa, ISO/IEC 18000-3M3), integrated firmware that offloads host processing, an I2C host interface (1.65V-1.95V / 3V-3.6V logic), and on-chip DC-DC converter for RF output. The device delivers up to 2 W RF output power into the antenna with adaptive automatic antenna tuning. The PN7160A1EV uses a dedicated ARM Cortex-M3 core running NXP's NCI firmware, which exposes a standardized NCI transport to the OS-level NFC service. This architecture lets the host processor treat the PN7160A1EV as a black-box NFC modem while NXP manages the low-level ISO 14443/15693/FeliCa stack internally, simplifying host driver development and accelerating time-to-market for NFC integration. Typical applications include NFC payment terminals (POS), mobile point-of-sale (mPOS), contactless access control, electronic identity verification, NFC-tag-based IoT provisioning, and wireless charging pairing using NFC. In point-of-sale terminals the PN7160A1EV is the contactless reader front-end; in smartphones and tablets it provides the NFC radio for Android HCE and Apple VAS. When designing with this device, follow NXP hardware design guide AN12988 for antenna matching, EMC compliance, and PCB layout for the VFBGA-64 land pattern. The integrated DC-DC converter requires careful inductor and capacitor selection near the IC, and the antenna tuning loop should use NXP's NFC Cockpit configuration tool. This page synthesizes distributor pricing, NCI-compliant alternatives, and reference design notes not found in the bare manufacturer datasheet, giving engineers a faster path to NFC integration than distributor catalog pages.
PN7160A1EV-C100K - NFC Controller, 13.56MHz, NCI, VFBGA-64 | NXP
The NXP Semiconductors PN7160A1EV-C100K is a high-performance NFC (Near Field Communication) plug-and-play controller with integrated firmware and an NCI (NFC Controller Interface) host interface, housed in a 64-ball VFBGA package. It operates at 13.56 MHz and supports the full set of contactless protocols including ISO 14443 (Type A/B), ISO 15693, FeliCa, MIFARE, and NFC Forum modes (Reader/Writer, Peer-to-Peer, Card Emulation). The part supports a wide supply range of 1.65 V to 1.95 V (VDD) and 3.0 V to 3.6 V (VBAT/PVDD), making it compatible with mobile devices and battery-powered systems. An NFC controller is a dedicated mixed-signal IC that handles the 13.56 MHz RF front-end (including modulation, demodulation, antenna tuning, and EMV/NFC framing) so that the host application processor does not need to manage real-time RF timing. Within the broader hierarchy, the PN7160A1EV sits as an NFC controller -> contactless reader/writer -> RF front-end IC -> wireless connectivity semiconductor. By offloading the entire ISO stack and providing integrated firmware (with NCI 2.0 host commands), the part enables fast integration into Android, Linux, RTOS, and bare-metal hosts without RF design expertise. Key features include up to 1.5 W RF output power, integrated EMVCo 3.1 and NFC Forum certification-ready firmware, automatic antenna tuning via an external variable capacitor bridge, integrated temperature monitoring, and low-power card-detection polling. The VFBGA-64 (4 mm x 4 mm) package supports compact PCB layouts typical of smartphones, tablets, payment terminals, and IoT devices. The host communicates over standard I2C up to 3.4 MHz, simplifying integration with most application processors. Architecturally, the PN7160A1EV uses a dedicated ARM Cortex-M0 microcontroller core running the integrated NFC firmware, an RF analog front-end supporting all major modulation schemes (ASK 10%/100%, BPSK), a power management unit with multiple LDO regulators, and an integrated balun-less transmitter requiring only an EMC filter. The device automatically manages RF collision avoidance, CRC, and anti-collision, reducing host MCU load. The /C100K suffix indicates firmware revision and packaging variant; the /C100 firmware is the latest production release, while the trailing K denotes a specific reel or production line code. Typical applications include NFC contactless payment terminals, smartphone and tablet NFC modems, smart wearables with payment/ticketing, IoT devices with tap-to-pair or NFC commissioning, and access-control readers. The combination of high RF output and integrated EMVCo-compliant firmware is especially valuable for payment-grade terminals where certification time is critical. When designing with this part, antenna matching is the single most important step: use the NXP NFC Cockpit configuration tool to tune the matching network and TXLDO voltage to the specific antenna geometry. The two VDD rails (1.8 V host I/O and 3.3 V RF/transmitter) must be decoupled with 100 nF + 1 µF ceramic capacitors placed within 2 mm of the supply balls. Always reserve GPIO/DWL_REQ for the host-to-controller interrupt handshake, and follow the reference PCB layout in the datasheet (controlled-impedance differential feed to the antenna pads, solid RF ground plane under the IC). This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, providing engineers with a single-source reference for NFC controller selection.

It operates the RF front-end at 13.56 MHz, supports FeliCa, ISO/IEC 14443 Type A/B, ISO/IEC 15693, MIFARE and the NFC Forum NCI specification, and is qualified for 1.65 V to 1.95 V digital I/O and 3.0 V to 3.6 V RF supply rails. An NFC controller is the analog/digital interface that powers the contactless radio in a host device. The PN7160A1EV integrates the RF front-end, the protocol stack, and a low-power NCI host interface so the application processor can drive tags, readers, peer-to-peer and card-emulation modes through a standardized I2C command set instead of a proprietary driver. It belongs to the broader taxonomy of NFC/RFID reader ICs -> contactless front-ends -> secure connectivity ICs, and complements NXP's PN71xx family by adding integrated, signed firmware. Key features include on-board load modulation drivers for card-emulation mode, automatic antenna tuning via the integrated VDD_TX and VDD_PA regulators, dynamic power control for battery-powered designs, a low-power standby mode with wake-up via the NCI interface, and integrated firmware that supports all NFC Forum tags and peer modes out of the box. The part also exposes GPIO and IRQ lines for host integration, and includes an integrated temperature sensor for thermal protection. The PN7160A1EV uses an ARM Cortex-M0 core for firmware execution, with hardware accelerators for crypto and framing. The integrated firmware is signed and field-upgradable through NCI, allowing OEMs to support new NFC Forum specifications and proprietary tag types without changing silicon. Designers benefit from the standardized NCI command set, which removes the need for a closed driver on the host processor. Typical applications include NFC payment terminals, mobile point-of-sale (mPOS) readers, secure pairing for Bluetooth/Wi-Fi accessories, ePassport and eID reader kiosks, smart-home commissioning via NFC, and automotive in-cabin wireless charging authentication. The plug-and-play firmware makes it especially attractive for OEMs that lack deep NFC protocol expertise. When designing with the PN7160A1EV-C100Y, observe the VFBGA-64 PCB layout guidelines for the 0.5 mm ball pitch: matched-impedance differential routing between the IC and the antenna matching network, a clean RF ground, and bulk capacitors close to VDD_TX and VDD_PA are essential for radiated performance and EMC compliance.

PN7160A1HN - NFC Plug & Play Controller, NCI 2.0 | NXP
The NXP PN7160A1HN is an NFC Plug and Play Controller with integrated firmware and NCI 2.0 host interface, housed in a 40-pin HVQFN (6 x 6 mm) package with exposed thermal pad. Operating from 1.65 V to 1.95 V (digital) and 3.0 V to 3.6 V (RF/analog), it supports 13.56 MHz contactless communication and is compliant with ISO 14443, ISO 15693, FeliCa, and NFC Forum standards. The device integrates a new-generation RF contactless front end, an ARM Cortex-M0 microcontroller core with pre-loaded NFC firmware, and an I2C (or SPI) NCI 2.0 host interface, eliminating the need for proprietary device drivers. What is an NFC controller? An NFC (Near Field Communication) controller is a contactless interface IC that drives an external antenna to communicate with tags, smartcards, and peer devices at 13.56 MHz. Compared to a bare RFID frontend, an NFC controller stacks an integrated ARM core + NCI firmware on top of the RF transceiver, exposing only a standardized host interface. NFC controllers sit within the broader hierarchy: NFC controller -> contact/contactless combo IC -> secure element -> NFC Forum-certified modules. NXP's PN7160 family specifically adds Plug & Play behavior so the host reads device descriptors and capability lists automatically, accelerating Linux/Android integration. Key features of the PN7160A1HN include I2C address 0x28 (hardware-fixed), support for card emulation, peer-to-peer, and reader/writer modes, automatic RF field detection with low-power polling down to a few microamps, and broadcast of NDEF message Type 2/3/4/5 tags. The integrated ARM Cortex-M0 executes NXP's NCI 2.0 firmware directly from internal ROM, removing external flash requirements and shortening design-in time. The I2C bus can be reconfigured to SPI through EEPROM settings. Technically, the PN7160A1HN combines an RF analog front end (with sub-1% carrier amplitude stability for card-emulation stability), a digital protocol engine that handles framing, CRC, and anti-collision per ISO 14443-3, and an embedded Cortex-M0 running the NCI stack. Differential TX outputs and two RX inputs drive a passive matched network; an external balun is not needed. Internal LDO blocks keep the analog, RF, and digital rails isolated for maximum PSRR on the RF driver supply. Typical applications include payment terminals, EMVCo contactless readers, NFC tablets and laptops, USB NFC dongles, smart home hubs with tap-to-pair, industrial tag readers, and access control panels. The wide 3.0 V to 5.5 V tolerant RF supply range and high output power help drive antennas through enclosures and PCBs. Designers should place the matching network within 5 mm of the TX1/TX2/RX1/RX2 pins and keep the 27.12 MHz crystal within 2 mm of XTAL1/XTAL2 with a guarded ground ring. The I2C SDA/SCL lines need 4.7 kohm pull-ups to VCC_IO; the IRQ pin should be wired to a host GPIO that can wake the system. Decoupling capacitors must be placed tightly across VBAT, VBAT_PA, and VDDIO pins. This page synthesizes current distributor pricing, same-package drop-in alternatives (PN7161B1HN variants, PN7150 families with different firmware), and practical PCB layout guidance not consolidated in the manufacturer datasheet, helping engineers compare the PN7160A1HN against its siblings and third-party equivalents in a single view.

It comes in a 40-pin HVQFN (6x6 mm) exposed pad package and operates from dual voltage rails: 1.65 V to 1.95 V for the host interface section and 3 V to 3.6 V for the main analog/digital section. An integrated DC-DC converter can be supplied directly from a 2.8 V to 5.5 V battery, simplifying power tree design in portable devices. An NFC controller is a dedicated mixed-signal IC that handles the analog RF front end (transmitter, receiver, AFE, antenna matching) plus the digital protocol stack required to communicate with contactless cards, tags, peer devices, and NFC readers. It sits between the host application processor (which speaks I²C, SPI, or NCI) and the external NFC antenna. Compared to host-side software implementations, an external NFC controller offloads timing-critical protocol handling, improves RF performance, and reduces host CPU load. The PN7160 belongs to the NFC controller (RFID reader IC) product family, with hypernyms: contactless transceiver -> RFID reader -> NFC front-end -> wireless connectivity IC. Key features include full ISO/IEC 14443 Type A/B, ISO/IEC 15693, FeliCa, and MIFARE Classic/Plus/Ultralight/DESFire support, integrated firmware for plug-and-play operation via the standardized NCI 1.0 host interface, automatic antenna tuning (AAT), low-power card detection (LPCD) modes, and support for Reader/Writer, Peer-to-Peer, and Card Emulation modes. The C100 firmware variant is the standard production firmware configuration as released by NXP. The integrated DC-DC and LDO architecture eliminates many external passives and supports direct battery connection between 2.8 V and 5.5 V. Architecturally, the PN7160 combines a high-efficiency RF output stage, an ARM Cortex-M0 core for protocol stack execution, on-chip non-volatile memory for the NCI firmware image, and integrated capacitive sensing for low-power card polling. The device implements the NCI 1.0 specification as defined by the NFC Forum, allowing it to be paired with any NCI-compliant host stack on Linux, Android, Windows, or RTOS-based platforms without modification. This abstraction layer means the same PN7160 silicon can be dropped into designs running NXP, ST, Linux, or third-party NFC middleware. Typical applications include NFC payment terminals (POS), mobile and wearable point-of-sale accessories, Bluetooth pairing and Wi-Fi handover via NFC tap, electronic door locks and access control readers, transit ticketing terminals, and consumer electronics pairing. The low-power card detection mode suits battery-powered access readers and IoT devices that must wake only on tag approach. Design consideration: antenna matching is critical for read range and regulatory compliance. Use NXP's PN7160 hardware design guide (AN12988) reference matching network. Provide adequate copper thermal relief under the exposed pad and ensure the I²C/SPI host lines include pull-ups per the bus specification.

PN7160A1HN/C100Y - NFC Plug & Play Controller 13.56MHz | NXP
The NXP PN7160A1HN/C100Y is a 13.56 MHz Near Field Communication (NFC) plug-and-play controller with an integrated NCI 2.0 host interface and on-chip firmware, packaged in a 40-pin VFQFN exposed-pad (HVQFN-40, 6x6 mm) form factor. It supports ISO/IEC 14443-A/B, ISO/IEC 15693, FeliCa, MIFARE Classic, MIFARE DESFire, MIFARE Ultralight, and NXP's proprietary NFC-DEP protocols at the air interface, and operates from a 1.65-1.95 V host-side (VDD) supply plus a 3.0-3.6 V NFC front-end (VBAT/VIN) supply over an I2C bus up to 1 MHz. The on-chip firmware handles RF collision resolution, NFC-A/B/F polling loops, and Type 1-5 tag emulation without host CPU involvement, enabling a true drop-in NFC front-end for Linux, Android, Windows, and RTOS systems. What is an NFC controller? An NFC controller is a contactless front-end IC that manages the 13.56 MHz RF link between a device and a contactless card, phone, or tag, offloading the RF protocol stack, AFE/DCI conditioning, and frame-level error handling from the application processor. Within the broader taxonomy, an NFC controller is a subcategory of RFID reader/transponder ICs, itself a subcategory of wireless connectivity ICs within RF & Wireless semiconductors. NXP's PN71xx family targets high-volume consumer and industrial integration where BOM simplification, certified RF performance, and host-CPU offload are critical. The PN7160A1HN/C100Y integrates a high-efficiency RF front-end capable of delivering up to 1 W of TX power to an externally tuned antenna while supporting autonomous low-power card detection. Integrated DC-DC converter and LDO blocks minimize external component count; the part needs only a single 3.3 V supply and a tuned 13.56 MHz antenna loop with EMC filter components. Host connectivity is over I2C with a standardized NCI 2.0 command set, so firmware upgrades and protocol additions are delivered as controller firmware updates rather than host driver rewrites. Typical applications include NFC payment terminals, EMVCo-compliant point-of-sale readers, access control readers, Bluetooth-pairing tap interfaces, IoT provisioning gateways, and industrial identification/logging systems. The PN7161 variant adds Apple Enhanced Contactless Polling (ECP) authorization; the PN7160A1HN/C100Y firmware (C100) does not include ECP and is therefore the default choice for non-Apple-certified designs. Design tip: route the I2C and IRQ lines away from the antenna loop and keep the antenna matching network within 5 mm of the TVSS pin. Provide a solid ground plane beneath the exposed pad (EP) and stitch it with 4-8 thermal vias for thermal relief - the PN7160 dissipates up to 500 mW during continuous RF transmission.

PN7160B1HN - NFC Plug & Play Controller with NCI | NXP
The NXP Semiconductors PN7160B1HN is an NFC Plug and Play Controller with integrated firmware and an NCI (NFC Controller Interface) interface, designed for rapid integration into a wide range of NFC-enabled systems. It operates at 13.56 MHz, supports FeliCa, ISO 14443, ISO 15693, and MIFARE standards, and connects to the host MCU through an SPI interface. Supply voltage is dual-rail at 1.65 V to 1.95 V (host interface) and 3 V to 3.6 V (RF/analog), and it ships in a 40-VFQFN exposed-pad package. According to the manufacturer datasheet, it supports all NFC Forum modes and includes native drivers for Android, Linux, and Windows. A Near Field Communication (NFC) controller is a contactless short-range radio transceiver that operates at 13.56 MHz and conforms to ISO/IEC 14443, ISO/IEC 15693, FeliCa, and NFC Forum specifications. NFC controllers sit in the wireless connectivity hierarchy between simple RFID readers and full application processors, providing peer-to-peer, reader/writer, and card-emulation functions to a host MCU via a standardized NCI command set. The PN7160 family targets consumer, industrial, and embedded-payment use cases where offloading the RF stack, low power draw, and fast host integration are priorities. Key features include integrated firmware that removes the need for host-side stack development, a high RF output power that enables reliable operation even with small antennas, and on-board dynamic power control (DPC) that adjusts transmit power based on field strength to limit current consumption. The device is qualified to operate over the -40 C to +85 C industrial range, and it supports extended-length APDUs required by EMVCo L1. A hardware reset pin, multiple GPIO lines, and an IRQ output simplify host bring-up. From an architecture standpoint, the PN7160 uses a dedicated firmware-controlled state machine with an embedded RF front-end. Because all protocol handling is on-chip, the host only needs to send standardized NCI commands; this keeps the host driver footprint small and lets the same firmware support multiple host operating systems. The exposed thermal pad on the 40-VFQFN package is essential for RF performance and must be soldered to the ground plane. Typical applications include contactless payment terminals, access-control readers, IoT provisioning, Bluetooth-pairing helpers, and e-Government document readers. The MPN suffix B1 denotes the integrated firmware variant. Design considerations center on antenna matching, EMC compliance, and PCB layout: the RF loop must be kept short, the exposed pad must be well-grounded, and the host SPI lines should be length-matched to avoid signal-integrity issues at high speeds.

NXP's PN7160 family sits at the RF front-end layer of an embedded system, typically positioned between the application processor (which runs the NFC application stack) and the antenna matching network. Unlike bare NFC frontends that require extensive firmware development, the PN7160 ships with pre-integrated firmware executed on an embedded Arm Cortex-M0 core, exposing a standardized NCI interface to the host. Key features include integrated firmware supporting reader/writer, peer-to-peer (P2P), and card-emulation modes, support for all NFC Forum NXP-specified modes, dedicated host interfaces including SPI/I2C, and built-in support for Android, Linux, and Windows host drivers. The HVQFN-40 package with exposed thermal pad provides good RF grounding and thermal dissipation for the integrated TX driver stages. The PN7160 also includes secure boot, secure firmware update, and hardware cryptographic accelerators for tag authentication in payment and access-control applications. Architecture-wise, the PN7160 uses an embedded Arm Cortex-M0 microcontroller running NXP's NCI firmware, an analog RF front-end supporting the full 13.56 MHz band, a digital protocol engine handling ISO 14443 type A/B, FeliCa, ISO 15693, NFC-DEP, and NFC Forum tag type 1/2/3/4/5, plus power-management circuitry. The integrated TX current limiter and dynamic power-control loops maintain regulatory compliance for radiated emissions across global RF standards.

PN7161A1EV - NFC Plug & Play Controller, 13.56MHz | NXP Semiconductors
The NXP Semiconductors PN7161A1EV is a near field communication (NFC) controller IC with integrated firmware and an NCI (NFC Controller Interface) host interface, housed in a 64-pin VFBGA package. The device operates at an RF frequency of 13.56 MHz and supports FeliCa, ISO 14443, ISO 15693, MIFARE, and NFC Forum protocols, making it a drop-in NFC frontend for embedded systems. It communicates with the host processor through an I2C interface at 1.65V to 1.95V (core) and 3.0V to 3.6V (I/O) supply rails. An NFC controller is a contactless communications IC responsible for the analog RF signal generation, modulation/demodulation, and protocol framing required to communicate with NFC tags, contactless smart cards, and NFC peer-to-peer devices. NFC controllers sit below the host application processor in the system hierarchy (NFC controller -> NFC frontend -> short-range wireless IC -> RF semiconductor) and rely on the host to run the upper NFC stack and application layer. Compared with discrete reader designs, an integrated NFC controller with embedded firmware reduces BOM count, accelerates time-to-market, and eases regulatory compliance for EMVCo and NFC Forum certification. Key features include a built-in antenna driver, integrated non-volatile memory for firmware and configuration, low-power wake-up via host-controlled polling, and native support for Apple Enhanced Contactless Polling (ECP) on the C100 firmware variant. The device targets USB, UART, SPI, and I2C hosts through a single NCI-compliant interface, and integrates the RF matching network driver output, eliminating many external components. The PN7161A1EV variant specifically enables Apple ECP after formal authorization, distinguishing it from the baseline PN7160 firmware builds. Typical applications include payment terminals (EMVCo contactless), point-of-sale readers, access control systems, and industrial NFC tag commissioning where reliable 13.56 MHz RF performance, low standby power, and minimal host CPU overhead are required. The integrated NCI interface also enables easy integration with Linux/Android NXP-NCI stacks and Windows NFC class extension drivers. When designing with the PN7161A1EV, ensure the antenna matching network is tuned for the chosen coil and the host platform's NCI driver stack supports the loaded firmware revision. Power-rail sequencing must place the 1.8V VBAT rail before VDDIO to avoid inrush into the RF section.
PN7161A1EV-C100K - NFC Plug & Play Controller with Apple ECP | NXP
The NXP Semiconductors PN7161A1EV-C100K is an NFC Plug and Play controller with integrated firmware and NCI interface, supporting FeliCa, ISO 14443, ISO 15693, MIFARE, and NFC Forum tag types at 13.56 MHz. It operates from a dual voltage rail (1.65 V to 1.95 V host interface, 3.0 V to 3.6 V RF supply), draws up to 290 mA peak, and is housed in a 64-ball VFBGA package. The /C100K variant adds Apple Enhanced Contactless Polling (ECP) support on top of the standard PN7161 firmware. What is an NFC controller? An NFC (Near Field Communication) controller is an integrated circuit that handles the 13.56 MHz RF front-end, the ISO 14443/ISO 15693/FeliCa protocol layers, and exposes a digital host interface (I2C, SPI, or NCI in the NXP case) so an application processor can read/write NFC tags, emulate cards, or perform peer-to-peer data exchange without writing low-level driver code. NFC controllers sit hierarchically under NFC/RFID ICs -> wireless transceivers -> semiconductor. The PN7161 family targets the higher level of this stack by integrating the RF matching network, antenna driver, and a complete NCI firmware image so OEMs can drop it onto a board and ship an NFC reader in days. Key features include a built-in antenna driver with adjustable output power, integrated non-volatile memory for firmware storage, hardware low-power wake-up via an NFC-field detector, and a high-output RF stage capable of driving typical antennas at over 1.5 W conducted. The /C100K firmware build supports Apple ECP, which is required for certain Apple Wallet terminal modes (Apple VAS, Apple ECP) and is otherwise identical to the /C100 build in terms of electrical and mechanical characteristics. The PN7161 architecture combines an Arm Cortex-M0 core for host-side command processing, an 80C51 core for real-time RF protocol handling, dedicated hardware for ISO 14443 A/B, ISO 15693, FeliCa, and NFC-Forum tag-type demodulation, and a silicon-graded RF front-end. The internal NVM stores the NCI firmware image, allowing field upgrades over the NCI interface and removing the need for an external flash on the smallest designs. Typical applications include NFC reader modules for point-of-sale (POS) terminals, Apple Wallet-compliant contactless payment readers, NFC tag reading/writing for access control, Bluetooth pairing via NFC, and consumer electronics such as printers and wearables. The integrated antenna driver simplifies BOM and PCB layout versus discrete RF front-end designs. When designing with this part, ensure a well-matched 50 ohm antenna network, follow NXP reference design (H/NXP-NXP-DRP-REF) layout guidelines for the RF matching area, and respect the moisture sensitivity level (MSL 3, 168 hours floor life) for VFBGA-64 handling. Use the NXP NCI host library on Linux, Android, or Windows to issue commands without writing low-level RF driver code.

PN7161A1EV-C100Y - NFC Plug & Play Controller, Apple ECP, VFBGA-64 | NXP
The NXP Semiconductors PN7161A1EV-C100Y is an NFC Plug and Play Controller with integrated firmware and NCI (NFC Controller Interface), housed in a 64-ball VFBGA package. It is a 13.56 MHz RFID reader IC supporting FeliCa, ISO 14443, ISO 15693, MIFARE, and NFC Forum protocols via an I2C host interface, supplied from a 1.65V-1.95V or 3.0V-3.6V dual-rail input. The /C100Y variant adds Apple Enhanced Contactless Polling (ECP) support on top of the standard PN7161 feature set, targeting iPhone-based wallet and access-control use cases. An NFC controller is a mixed-signal IC that handles the physical-layer (RF front-end, modulation/demodulation) and low-level protocol stack of an ISO 14443/ISO 15693 reader system, offloading these real-time tasks from the host application processor. The host communicates via NCI (a standardized command set defined by the NFC Forum) over I2C, and the PN7161 family adds integrated firmware (Plug and Play) so designers do not need to develop or certify a contactless stack themselves. This places the PN7161 in the taxonomy: NFC controller -> contactless reader -> 13.56 MHz RF IC -> wireless/RFID IC -> semiconductor. Key features include integrated RF front-end, automatic ECP polling per Apple specification, support for all major contactless standards (ISO 14443 A/B, ISO 15693, FeliCa, MIFARE Classic/Ultralight/DESFire, NFC-DEP), NCI 2.0-compliant host interface, and low-power standby/Polling loop modes. The integrated DC-to-DC control supports direct battery supply in the 2.8V-5.5V range when paired with an NXP PCA941xA companion, simplifying power-tree design in portable terminals. Architecturally, the PN7161 integrates an ARM Cortex-M0 core for on-chip firmware execution, an AGC-controlled RF transmitter, multiple receiver inputs for better small-antenna performance, and a high-efficiency PMU. Compared with discrete reader ICs, the integrated firmware removes a major certification risk and reduces time-to-market for OEM payment, access, and pairing products. Typical applications include NFC payment terminals, point-of-sale (POS) readers, access control and identity readers, Bluetooth/NFC pairing, and Apple Wallet VAS/Value-Added Services. The wide host interface and OS-agnostic NCI make it compatible with Linux, Android, Windows, and RTOS-based hosts. Design consideration: select an external DC-DC such as the PCA9410A/PCA9411A/PCA9412A when VIN exceeds 5.5V or when higher output power is required. Without a DC-DC, the part operates from a clean 1.8V or 3.3V rail.

It supports FeliCa, ISO 14443-A/B, ISO 15693, MIFARE Classic, MIFARE DESFire, and NXP NTAG/NFC Forum Type 1-5 tag protocols through its integrated transceiver, AFE, and on-chip matching network. An NFC controller is a mixed-signal semiconductor that combines a 13.56 MHz RF front-end (transmitter, receiver, and antenna matching) with a digital protocol stack. It sits below the application processor in a connected device's architecture: host SoC -> NCI/I2C -> NFC controller -> RF field -> contactless tag/reader/P2P peer. Within the broader taxonomy the PN7161A1HN belongs to: NFC controller -> contactless front-end IC -> wireless connectivity -> semiconductor. Offloading RF and protocol handling from the host reduces BOM count, firmware effort, and EMC risk for OEMs integrating contactless features. Key features include a single supply input (1.65-3.6 V with internal DC-DC supporting 3.0-5.5 V VBAT variants on related part numbers), up to 1.5 W output power delivered to the antenna load, ultra-low-power card-detection polling modes that draw roughly 100 uA in LPCD, integrated firmware loadable over I2C, and hardware cryptographic accelerators for MIFARE Classic Crypto1 and AES-128. An exposed thermal pad keeps theta_JA low enough for handheld and POS-terminal designs without an external heatsink. The PN7161A1HN embeds an Arm Cortex-M0 core that runs the NCI framing, AFI/anti-collision, and proprietary NXP extensions. The integrated TX LDO and current-limiting circuitry protect against antenna detuning and foreign-field events, while the embedded matching network simplifies PCB antenna design - external components are limited to a single EMC filter and the antenna coil itself. Typical applications include NFC tap-to-pay terminals, smartphone and tablet accessory sidecar PCBs, Bluetooth-pairing smart speakers, POS/PIN-pad readers, eBike and EV-charging authentication, and contactless firmware-update kiosks. Apple ECP enables a deterministic contactless handshake with iOS 17+ for wallet card selection and digital car-key workflows. When designing with this part, follow NXP application note AN12364 for the recommended antenna matching network and EMC filter component values. Keep the antenna trace loop area below 1 cm² away from the IC to minimize stray coupling, and provide a low-impedance ground plane under the exposed pad using at least nine thermal vias to the inner ground layer. This page consolidates distributor pricing, verified pin-compatible alternatives from the PN7160/PN7161 family, and practical layout notes not aggregated on the manufacturer datasheet.
PN7161A1HN-C100E - NFC Plug & Play Controller with Apple ECP | NXP
The NXP Semiconductors PN7161A1HN-C100E is an NFC (Near Field Communication) Plug and Play controller with integrated firmware, an NCI (NFC Controller Interface) host interface, and native support for Apple Enhanced Contactless Polling (ECP), housed in a 40-pin HVQFN (6 mm x 6 mm) exposed-pad module. It targets a 13.56 MHz RF carrier and supports FeliCa, ISO 14443 (Type A/B), ISO 15693, MIFARE, and NFC Forum tag types, while exposing an I2C host interface at addresses selectable between 1.65V-1.95V (host) and 3.0V-3.6V (RF/PMU) supply domains. An NFC controller is a mixed-signal IC combining an RF analog front-end, a digital protocol stack (NCI 1.0 / 2.0), and an embedded firmware state machine that offloads host-side polling, anti-collision, and tag/RFID reader transactions. The PN7161 belongs to the broader NXP NFC controller family (PN5180, PN5190, PN7220, PN7150, PN7160), positioned as a drop-in upgrade for designers migrating from PN7150/PN7159 and seeking lower host CPU overhead. It is a key subcategory of RFID Reader ICs inside RF Identification, which sits in the Wireless / Sensor Network technology stack alongside Wi-Fi and BLE combo parts. Key features include full NCI 1.0/2.0 host compliance, embedded firmware for autonomous polling, Apple ECP support, support for all NFC Forum modes (Reader/Writer, Peer-to-Peer, Card Emulation), an integrated LDO/DC-DC for the RF section, and a single I2C interface. The integrated firmware reduces host code size and minimizes the need for host CPU interrupts, accelerating Linux, Android, and RTOS porting on i.MX, LPC, and Kinetis MCU platforms. The 40-pin HVQFN exposed pad also provides a low-thermal-resistance path, supporting continuous RF field generation. Architecturally, the PN7161A1HN-C100E pairs an ARM Cortex-M0 core with NXP's proven analog demodulator IP, on-chip tuning capacitors, and direct battery connection support through the integrated VANT (antenna supply) booster. This reduces external BOM (no external LDO required) and simplifies PCB layout for POS terminals, access control readers, and IoT-NFC bridges. Apple ECP authorization (NDA-gated firmware variant) requires registration with Apple MFi to enable ECP features - the silicon supports it but the firmware unlock is a software/license step. Typical applications include payment terminals (POS), physical access control readers, NFC tag readers in printers/consumer electronics, automotive infotainment NFC pairing (AEC-Q100 subscription grade not in -C100E suffix), and IoT commissioning bridges. Designers choose it over PN7150 for lower BOM, lower host CPU load, and Apple ECP readiness, and over PN5180/PN5190 when a higher-level NCI interface is preferred over a register-level PHY. When designing with this part, ensure the PCB antenna matching network targets 13.56 MHz with a Q below 35 to meet ISO 14443 bandwidth, and route the exposed thermal pad with at least 9 thermal vias to a continuous ground pour. Because the I2C SDA/SCL lines require pull-ups per the NCI specification, populate them per the typical application schematic and verify the host MCU's I2C clock-stretching tolerance - NCI polling bursts can stretch the clock longer than naive I2C controllers tolerate.
PN7161A1HN-C100Y - NFC Plug & Play Controller | NXP | 40-VFQFN
The NXP Semiconductors PN7161A1HN-C100Y is an NFC Plug and Play controller with integrated firmware and NCI (NXP NFC Controller Interface), operating at 13.56 MHz and supporting FeliCa, ISO 14443, ISO 15693, and MIFARE contactless protocols in a 40-pin HVQFN (SOT1655-1) exposed-pad package. This PN7161 variant specifically adds support for Apple ECP (Enhanced Contactless Polling), enabling seamless integration with Apple devices. The device operates from dual supply rails of 1.65V to 1.95V (typically 1.8V) and 3.0V to 3.6V for the host interface and RF analog sections respectively. The integrated firmware eliminates the need for a host-resident NFC stack, dramatically reducing host code size and design-in complexity. Host communication is handled via I²C, supporting standard MCUs from NXP's LPC, Kinetis, and i.MX families as well as third-party controllers. Background: An NFC (Near Field Communication) controller is a specialized mixed-signal IC that manages the physical and protocol layers of 13.56 MHz contactless communication, including RF field generation, demodulation, modulation, anti-collision, and cryptographic authentication for tags/cards. NFC controllers sit within the broader hierarchy of RF identification ICs -> RFID reader/transponder ICs -> wireless connectivity -> semiconductor, providing the lowest-level hardware interface while higher software layers (NCI, NFC Forum, NDEF) handle application logic. Modern plug-and-play NFC controllers integrate the full firmware stack so the host processor only needs to issue high-level commands, making them functionally distinct from RFID reader chips that require an external stack. Key features include a high RF output power supporting typical NFC reader ranges, low standby current suitable for always-on applications, support for EMVCo and NFC Forum compliance, and a single 40-pin package that consolidates all functions to minimize external BOM. The exposed thermal pad enables efficient heat dissipation in compact designs. The C100Y variant is the Apple ECP-enabled firmware configuration shipped in production packaging quantities, while the base PN7160 supports the same hardware without Apple-ECP-specific code extensions. The integrated ARM Cortex-M0 core handles all on-chip processing, offloading real-time NFC protocol timing from the application processor. An on-chip LDO and DC-DC converter generate internal supply rails from a single external 3.3V feed, simplifying power-tree design. The device also includes EEPROM for firmware patches and configuration storage, so field updates do not require external memory components. Typical applications include NFC payment terminals, Bluetooth pairing via NFC, smart home commissioning, wireless charging authentication, access control readers, and OEM authentication tags. The Apple ECP support specifically targets iPhone-based tap-to-pair and tap-to-pay use cases. When designing with this controller, follow NXP's reference antenna design guidelines and ensure proper impedance matching for the matching network components to achieve the rated RF output power across all supported protocols.

Typical applications include NFC payment terminals, mobile point-of-sale (mPOS) devices, Bluetooth-pairing tags, automotive digital key systems, eGovernment / eID readers, and IoT provisioning via NFC. The combination of NCI host interface and integrated firmware makes it especially attractive for platforms running Android or Linux where Linux NCI drivers are already available. When designing with the PN7161B1EV, note that it requires an external matching network and antenna tuned to 13.56 MHz; bypass capacitors on VCC are mandatory and the exposed pad must be soldered to the ground plane for thermal dissipation and RF return. Avoid routing digital signal traces beneath the antenna area to minimize detuning. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the NXP datasheet.

An NFC controller is a contactless front-end IC that manages RF communication with NFC tags, smart cards, and peer devices at 13.56 MHz, exposing the wireless protocol stack to a host processor through a command-based interface such as NCI. Within the system hierarchy, the PN7161 sits between an application processor (the host) and the antenna matching network, falling into the RF & Wireless > NFC Controllers category. It enables payment terminals, access control, and consumer electronics to add NFC functionality without exposing the host to low-level RF protocol handling. Key features include integrated FW, hardware support for Apple ECP (after formal authorization), SPI/host interface, and dynamic power control of the RF output stage. The integrated matching-capable TXLDO and automatic EMD (electromagnetic disturbance) handling simplify antenna design and EMC compliance for OEM integrators building payment or peer-to-peer products. The PN7161B1 architecture builds on NXP's NCI 2.0 standard, exposing a standardized host command set that abstracts the RF protocol stack. The C100K firmware differentiates it from the C100 (PN7160 baseline) and C100Y firmware variants in the same VFBGA-64 footprint, allowing PCB reuse while selecting the feature set needed for Apple-ecosystem interoperability. Typical applications include payment terminals, NFC point-of-sale readers, access control readers, and consumer electronics such as printers, smart appliances, and IoT gateways that need to interact with contactless cards or phones. Industrial HMI panels, EV charging stations, and access control readers also benefit from its peer-to-peer and card-emulation modes. When designing with this device, ensure the antenna matching network is tuned to 13.56 MHz with a Q-factor appropriate for the target card types. Because the ECP feature requires Apple authorization, the firmware image provisioned at NXP must match the integrator's license before ECP commands are accepted by an iPhone or Apple Watch in field. This page synthesizes distributor pricing, drop-in firmware variants within the PN7161 family, and practical RF design notes that are not consolidated in the manufacturer datasheet.

An NFC controller is a radio-frequency identification transceiver that implements the ISO/IEC 14443 and ISO/IEC 15693 contactless protocols, allowing a host processor to read/write NFC tags and emulate contactless smart cards. NFC controllers sit below the operating system NFC abstraction layer, above the antenna matching network, and within the broader category of RFID reader ICs and short-range wireless transceivers. By integrating the analog front end, protocol stack, and firmware, parts such as the PN7161 remove the need for the application MCU to handle millisecond-level RF timing. The PN7161B1 supports automatic RF output power configuration up to +15 dBm into a 50 ohm load, a host-controlled SPI interface (PN7160 also offers I2C), and integrated dynamic power control (DPC) that adjusts output power to compensate for detuned antennas. Supply domains include 1.65 V to 1.95 V (host IO) and 3.0 V to 3.6 V (RF analog), with deep-sleep current below 15 uA. The C100Y firmware extends standard PN7161 NCI polling by enabling Apple ECP, which speeds up iPhone reader interactions for payment, loyalty, and identity applications. This part fits best in point-of-sale terminals, mobile point-of-sale (mPOS) dongles, NFC-Forum peer-to-peer accessories, and smart-home commissioning hubs that must interoperate with iOS devices in addition to Android. The VFBGA-64 footprint is a low-profile package suited to space-constrained products, and the integrated firmware drastically shortens host-side development cycles compared to discrete RF front-ends. Designers do not need prior RF expertise - NXP provides reference antenna matching values and pre-tuned firmware images. Key design trade-offs include the 0.8 mm BGA pitch, which requires assembly with ENIG or ENEPIG surface finish and controlled-impedance routing, plus a separate reset logic to enter download mode for firmware updates. Because the PN7161B1 uses SPI while the PN7160 supports both SPI and I2C, verify host MCU peripherals before substituting. For Apple-only ECP readers the C100Y variant is required; the C100 base firmware omits ECP and is therefore not iOS-optimal.
PN7161B1HN - NFC Controller, 13.56MHz, NCI, VFQFN-40 | NXP
The NXP PN7161B1HN is an NFC controller IC operating at 13.56 MHz with an SPI host interface and NCI (NFC Controller Interface), housed in a 40-pin VFQFN exposed-pad package. It is designed to support EMV L1 compliance, NFC Forum applications, Apple ECP (Enhanced Contactless Polling), FeliCa, ISO 14443, ISO 15693, and MIFARE protocols. The PN7161B1HN is intended for integration into payment terminals, mobile point-of-sale systems, and consumer electronics that require high-performance contactless front-ends. An NFC controller is a near-field communication front-end IC that handles the analog RF layer (antenna tuning, modulation/demodulation) and exposes a standardized digital command interface (NCI) to a host application processor. NCI controllers like the PN7161B1HN offload the timing-critical contactless protocol stack from the host CPU, enabling the application processor to run the user-facing payment, access-control, or pairing logic while the PN7161B1HN manages RF compliance and certification requirements. Within the broader system hierarchy, an NFC controller sits under the wireless connectivity IC category, alongside Wi-Fi and Bluetooth transceivers, and is typically paired with a secure element for payment systems. Key features include integrated firmware supporting EMV L1 and NFC Forum specifications, a host SPI interface up to 15 MHz, support for Apple ECP (Enhanced Contactless Polling), and dynamic power control. The device supports a wide supply range: 1.65 V to 1.95 V for the digital interface (typical 1.8 V) and 3.0 V to 3.6 V for the RF analog and main supply (typical 3.3 V). The exposed thermal pad on the VFQFN-40 package enables efficient heat dissipation during continuous RF operation. Typical RF output power is sufficient to drive standard contactless reader antennas at the 13.56 MHz carrier frequency used across all major contactless standards. The PN7161B1HN integrates a high-performance ARM Cortex-M0 microcontroller core running NXP's certified NFC firmware stack, an AWC (Active Waveform Control) transceiver for improved RF performance, and on-chip tuning capacitor banks. The architecture separates the host-facing digital domain (1.8 V SPI/I2C) from the RF/analog domain (3.3 V), simplifying integration with low-voltage application processors. EMV L1 certification pre-compliance reduces end-product time to market for payment terminal designs. Typical applications include EMV contactless payment terminals, Apple Pay merchant terminals (ECP-enabled), NFC point-of-sale readers, access control readers, and consumer electronics pairing/identification. The PN7161B1HN is also deployed in industrial NFC readers where EMV and NFC Forum certification is required. When designing with the PN7161B1HN, place the matching network and EMC filter components as close as possible to the RFD_TX/RX pins and ensure the exposed pad is soldered to a sufficient ground plane for thermal relief. The host should run NXP's NCI driver stack and validate antenna matching against the target environment (metal housings, ferrite sheets) to achieve EMV L1 compliance.

PN7161B1HN-C100E - NFC Controller with NCI, Apple ECP | NXP
The NXP Semiconductors PN7161B1HN-C100E is an EMV L1 compliant Near Field Communication (NFC) controller with an NCI (NFC Controller Interface) and integrated firmware, supporting 13.56 MHz contactless operation in a 40-pin HVQFN (6x6 mm) exposed-pad package. It operates from 1.65V to 1.95V and 3.0V to 3.6V supply rails, interfaces to the host through SPI, and supports FeliCa, ISO 14443, ISO 15693, MIFARE, and NFC Forum applications with Apple Enhanced Contactless Polling (ECP) authorization. The PN7161B1HN-C100E is the production version designated by the /C100E firmware bundle, optimized for Apple Wallet and EMV L1 use cases. An NFC controller (also called an NFC front-end or NCI controller) is a semiconductor that sits between a host processor and an NFC antenna, handling the 13.56 MHz RF link, ISO protocol stack, and cryptography offload so that the application processor can speak to the reader through a standardized high-level interface (NCI). Within the system hierarchy, it sits at the interconnect layer: NFC controller -> NFC front-end -> wireless connectivity IC -> semiconductor. It enables contactless payments, ticketing, access control, and peer-to-peer data exchange without burdening the application MCU with real-time RF processing. Key features include full EMV L1 compliance, NCI 1.0 host interface, integrated firmware (PN7161B1HN/C100E bundle), Apple ECP support, automatic ECP handling for Apple Pay, automatic antenna tuning via the integrated VDD_TX driver, low-power standby mode with polling, and on-chip EMC filtering. The device supports both 1.8V and 3.3V host logic via separate supply pins (VDD_IO and VDD), simplifying integration with modern application processors without level shifters. The PN7161B1HN/C100E firmware adds turnkey EMV payment stack handling and Apple Wallet ECP behavior, dramatically reducing host-side software development. Compared to the PN7160, the PN7161 adds Apple ECP support after formal authorization. Compared to discrete RF front-ends (e.g. discrete NFC reader ICs without integrated firmware), the PN7161B1HN-C100E delivers a smaller BOM, simpler EMC compliance path, and faster time to market for payment terminals. Typical applications include point-of-sale (POS) terminals, mobile payment readers, access control readers, transit ticketing terminals, NFC-enabled IoT hubs, and Apple Pay-compatible accessory products. In each case the controller integrates seamlessly into designs that already have a host MCU running Linux, Android, or an RTOS, with NCI driver support available from NXP and mainline Android. When designing with this part, follow NXP application note AN11892 for the antenna matching network and reference the OM27160 evaluation board for the certified antenna design. Pay attention to the exposed-pad (EP) PCB land pattern for thermal dissipation and RF grounding, and verify that the host NCI driver is matched to the firmware bundle revision indicated on the top marking.
