PN7161B1EV-C100K Обзор
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.

Типичное применение
PN7161B1EV-C100K подходит для 6 применениеs: Contactless Payment Terminal, Access Control Reader, Consumer Electronics / IoT Pairing, EV Charging Authentication, Industrial HMI / Diagnostic Reader, Smart Home / IoT Gateway.
Contactless Payment Terminal
The PN7161B1EV-C100K fits payment terminals because it supports all major contactless protocols (ISO 14443 A/B, FeliCa, MIFARE, ISO 15693) at 13.56 MHz and exposes a standardized NCI 2.0 host interface. The Apple ECP firmware profile enables certified interaction with iPhones and Apple Watch for in-app payments and loyalty flows. Placed between the payment application processor and the antenna matching network, it handles modulation, anti-collision, and crypto acceleration offloading the host from real-time RF protocol tasks. Integrated firmware shortens time-to-market versus register-level RF front-ends.

Access Control Reader
Access control readers benefit from the PN7161B1EV-C100K's 13.56 MHz RF front-end and MIFARE DESFire support, which covers corporate badge and student-ID credentials. The integrated NCI host interface offloads protocol handling from the access controller MCU, freeing CPU cycles for door logic and audit storage. The chip's low standby current (10.5 uA typical) suits battery-backed or PoE-powered door readers. Apple ECP support enables mobile-credential readers that accept iPhone/Apple Wallet as a virtual badge.
Рекомендуется
Consumer Electronics / IoT Pairing
The PN7161B1EV-C100K is suited to consumer electronics such as printers, smart speakers, and appliances that need tap-to-pair or NFC-based Wi-Fi/Bluetooth handover. The integrated NCI host interface over SPI simplifies driver development on Linux/Android application processors. The 64-ball VFBGA package and 10.5 uA polling current support compact battery-powered products where standby drain is critical. Apple ECP firmware adds compatibility with iPhone-based pairing and configuration flows beyond standard NFC Forum protocols.
Рекомендуется
EV Charging Authentication
EV charging stations use NFC for user authentication and ISO 15118 plug-and-charge bridging. The PN7161B1EV-C100K's ISO 14443 and NFC Forum peer-to-peer support covers credit-card credentials and PnC token transfer. The 64-ball VFBGA footprint fits inside the station's compact controller module, and the 3.0-3.6 V analog rail aligns with the station's 3.3 V power tree. Apple ECP support enables iPhone-based EV charging session initiation for fleets and consumer charging networks.
Рекомендуется
Industrial HMI / Diagnostic Reader
Industrial HMIs and service tools use the PN7161B1EV-C100K to read NFC tags embedded in field equipment for diagnostics, calibration data, or operator identification. The wide operating temperature and the integrated firmware simplify industrial certifications. The PN7161B1EV/C100K's SPI host interface connects to typical industrial STM32 or i.MX RT host MCUs. Apple ECP support enables technician tablets to authenticate via iPhone for machine setup and audit logs.
Рекомендуется
Smart Home / IoT Gateway
Smart-home gateways and IoT hubs use the PN7161B1EV-C100K to onboard devices via NFC and to read contactless utility/sensor tags. The integrated firmware means no host-side RF stack development, and the SPI host interface works with Linux gateways that already expose /dev/spidev. The Apple ECP firmware lets iPhone users tap to provision Wi-Fi, Thread, or custom IoT credentials into the system, simplifying first-time setup. The chip's low polling current supports always-on gateway operation.

Заметки по проектированию
The PN7161B1EV-C100K requires two supply rails - 1.65-1.95 V (VDDIO/digital) and 3.0-3.6 V (VDD/RF analog). Place 100 nF + 1 uF ceramic decoupling capacitors as close as possible to each supply ball on the 64-ball VFBGA. A bulk 4.7 uF capacitor on each rail reduces ripple injected from upstream DC/DC switching noise, which would otherwise degrade receiver sensitivity at 13.56 MHz.
Route the SPI host interface traces (MOSI, MISO, CLK, CS) with 50 ohm impedance and keep them short to avoid ringing. Place the PN7161B1EV/C100K away from switching DC/DC nodes and noisy clock harmonics. The antenna matching components (L, C) must sit within 5 mm of the TX/RX balls to minimize stray capacitance and preserve the matching network's Q-factor at 13.56 MHz.
Apple ECP functionality is only available after formal Apple authorization - the firmware code (C100K suffix) does not by itself grant ECP interoperability. Verify that the part variant shipped by your distributor matches the firmware code you are licensed to use. Also, the 64-ball VFBGA requires careful PCB land pattern design - refer to the NXP PN7160_PN7161 datasheet land pattern appendix for non-solder-mask-defined (NSMD) pad recommendations to avoid BGA head-in-pillow defects during reflow.
Estimated: at 13.56 MHz with a 50 ohm-controlled impedance RF trace of length ~10 mm, insertion loss is approximately 0.2-0.3 dB based on typical FR-4 substrate loss. Beyond 20 mm of RF trace length, the antenna Q-factor degrades noticeably and the matching network will need re-tuning. Place the PN7161B1EV/C100K such that the trace from TX/RX balls to the EMC filter and matching network is the shortest path on the top side of the PCB.
