Product details
Overview
PN7161B1HN/C100Y from NXP Semiconductors is a SPI-interface NFC controller with integrated firmware, supporting ISO/IEC 14443A/B, ISO/IEC 15693, MIFARE, FeliCa, and NFC Forum T4T/T5T protocols. It delivers 1.3 W transmitter output power, achieves 20 mV(p-p) card-mode receiver sensitivity, and operates across 2.8–5.5 V battery supply. It enables autonomous card emulation during host shutdown in mobile and portable devices.
For engineers reviewing the PN7161B1HN/C100Y datasheet, PN7161B1HN/C100Y pinout, PN7161B1HN/C100Y application, or PN7161B1HN/C100Y equivalent, key selection criteria include ECP support (Apple-authorized), NCI 2.0 compliance, HVQFN40 package compatibility, low-power polling loop current (100 μA typical), and firmware version 12.50.05 pre-installed.
Technical Context
The PN7161B1HN/C100Y implements an NCI 2.0–compliant host interface over SPI, with embedded ARM Cortex-M0 coprocessor, 128 kB ROM, 28 kB EEPROM, and 8 kB SRAM. Its RF front-end supports active load modulation and Enhanced Dynamic LMA for extended range in card mode.
It integrates a dual-supply transmitter (VDD(TX) 2.7–5.25 V), independent 5° LMA phase adjustment per Type A/B/F, dynamic power control compliant with NFC standards, and autonomous wake-up via RF field or internal timer - all while maintaining Hard Power Down current ≤16 μA at 3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Battery Supply Range | 2.8 V to 5.5 V - enables direct connection to single-cell Li-ion or USB-powered systems without external regulators. |
| Transmitter Output Power | 1.3 W - sufficient for robust reader operation with compact antennas in space-constrained mobile designs. |
| Card Mode Sensitivity | 20 mV(p-p) - ensures reliable detection of weak-field cards and tags, critical for small-form-factor antenna integration. |
| Low-Power Polling Current | 100 μA typical at 3.6 V, 500 ms loop - extends battery life in always-on NFC discovery applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7160B1HN/C100Y | No ECP support; identical pinout, SPI interface, firmware v12.50.05, and HVQFN40 package. | Lacks Apple ECP certification - unsuitable for iOS-integrated payment or authentication workflows. | Select when ECP is not required and cost optimization is prioritized; full hardware compatibility enables drop-in substitution. |
| PN7161B1EV/C100Y | VFBGA64 package (64-ball); same SPI interface, firmware v12.50.05, and ECP capability. | Higher I/O density and smaller footprint (4.0 × 4.0 mm), but requires tighter layout control and BGA rework capability. | Choose for space-constrained designs where PCB real estate is premium and BGA assembly is available. |
Compared with PN7160B1HN/C100Y, PN7161B1HN/C100Y adds ECP for iOS interoperability without changing pinout or power requirements; versus PN7161B1EV/C100Y, it trades BGA miniaturization for QFN manufacturability and thermal performance.

FAQ
What is the primary interface type supported by PN7161B1HN/C100Y?
PN7161B1HN/C100Y supports SPI-bus (High-speed mode) as its host interface, compliant with NCI 2.0 protocol. It does not support I²C - the "B" in the part number explicitly denotes SPI configuration. This interface enables deterministic, low-latency command exchange between the host processor and PN7161B1HN/C100Y for reader, card, and P2P operations.
Does PN7161B1HN/C100Y support Apple's Enhanced Contactless Polling (ECP)?
Yes, PN7161B1HN/C100Y supports ECP as a core differentiator from the PN7160 series. This feature is enabled in firmware versions ≥12.50.05 and requires formal authorization from Apple. ECP improves polling efficiency and reliability with iOS devices, making PN7161B1HN/C100Y suitable for certified mobile payment and authentication applications.
What package type and dimensions does PN7161B1HN/C100Y use?
PN7161B1HN/C100Y uses the HVQFN40 (SOT618-1) package: a 6.0 mm × 6.0 mm × 0.85 mm thermally enhanced quad flat no-lead package with 40 terminals and an exposed center thermal pad (VSS). Pin pitch is 0.5 mm, and the package is RoHS-compliant and halogen-free per marking code "D".
Can PN7161B1HN/C100Y operate autonomously without host processor involvement?
Yes, PN7161B1HN/C100Y supports Autonomous mode: when configured by the host and VDD(PAD) is removed, it maintains card emulation (T4T) using internal EEPROM-stored NDEF data - even with the host fully powered down. Wake-up is triggered by RF field or internal timer, enabling true "always-on" NFC functionality.
What is the minimum supply current consumption of PN7161B1HN/C100Y in low-power polling mode?
In low-power polling loop mode at 3.6 V VBAT and 500 ms loop interval, PN7161B1HN/C100Y consumes 100 μA typical - verified in Table 1 of the datasheet. This value reflects active RF detection with minimal block activation, enabling multi-week battery life in wearables and remote sensors relying on periodic NFC discovery.
