Product details
Overview
PN7161B1EV/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 wearable devices.
For engineers reviewing the PN7161B1EV/C100Y datasheet, PN7161B1EV/C100Y pinout, PN7161B1EV/C100Y application, or PN7161B1EV/C100Y equivalent, this page provides verified technical context, validated pin functions, confirmed ECP support (Apple-authorized), real-world low-power polling loop current (100 μA), and two field-tested alternative parts for NFC system design.
Technical Context
The PN7161B1EV/C100Y implements an NCI 2.0-compliant host interface over SPI, with embedded ARM Cortex-M0 processor, 128 kB ROM, 28 kB EEPROM, and 8 kB SRAM. Its RF front-end supports dynamic power control, enhanced DLMA, and independent 5° LMA phase adjustment per Type A/B/F protocol - enabling robust communication with small antennas and extended range in card mode.
It features dual power domains: VBAT (2.8–5.5 V) powers the RF transmitter and core logic, while VDD(PAD) (3.0–3.6 V) supplies the SPI interface. Autonomous operation is enabled via Hard Power Down and Standby states, with wake-up triggered by RF field, internal timer, or WKUP_REQ signal - all without host intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7160B1EV/C100Y | Same VFBGA64 package and SPI interface, but lacks ECP support and ships with identical 12.50.05 firmware minus Apple authorization | Valid for Android-only deployments where ECP is unnecessary; no EMVCo ECP certification path | Select when cost sensitivity outweighs iOS ecosystem requirements and ECP is not mandated |
| ST25DV04K-IER | I²C-only interface, 4 kbit EEPROM + NFC interface, no embedded MCU or NCI stack; requires external host processing | Targeted at simple NFC tag emulation with static data - not suitable for reader/writer or P2P roles | Choose only for passive tag replacement with minimal BOM; not a functional substitute for PN7161B1EV/C100Y's controller capabilities |
Compared with PN7160B1EV/C100Y, PN7161B1EV/C100Y adds certified ECP functionality critical for iOS integration, while ST25DV04K-IER serves a fundamentally different role as a memory+interface IC rather than a full NFC controller - making it unsuitable for autonomous operation or complex protocol handling.

FAQ
What distinguishes PN7161B1EV/C100Y from PN7160B1EV/C100Y?
PN7161B1EV/C100Y includes Apple-authorized Enhanced Contactless Polling (ECP) support and EMVCo ECP profile compliance, which PN7160B1EV/C100Y lacks. Both share identical VFBGA64 packaging, SPI interface, 12.50.05 firmware base, and electrical specifications - but only PN7161B1EV/C100Y can be formally authorized for iOS NFC integration. The model ID (0x71 vs 0x61) is read from byte 9 of CORE_RESET_NTF.
Does PN7161B1EV/C100Y support autonomous card emulation without host CPU power?
Yes. PN7161B1EV/C100Y supports autonomous card emulation in Standby mode with VBAT applied and VDD(PAD) removed. It maintains T4T NDEF short records in EEPROM and responds to RF readers independently - enabling tap-to-pay functionality in smartphones or wearables even when the application processor is fully powered down.
What is the minimum current consumption of PN7161B1EV/C100Y in low-power polling mode?
PN7161B1EV/C100Y consumes 100 μA typical in low-power polling loop mode at VBAT = 3.6 V and 500 ms loop interval. This value assumes use of the enhanced RF detector and optimized firmware configuration - enabling multi-day battery life in always-on NFC tag emulation applications such as smart locks or access badges.
Which antenna interface configuration does PN7161B1EV/C100Y require?
PN7161B1EV/C100Y uses differential antenna outputs TX1/TX2 and dedicated antenna sense terminals ANT1/ANT2. It requires an external LC matching network tuned to sink ≤250 mA continuous current, with antenna impedance matched to 50 Ω. The VFBGA64 package places ANT1 (F7) and ANT2 (E7) adjacent for minimal trace length and balanced layout.
Is PN7161B1EV/C100Y compatible with NFC Forum certification requirements?
Yes. PN7161B1EV/C100Y meets NFC Forum Device Requirements and supports NFC Forum certification for reader, card, and P2P modes up to firmware version 12.50.0A. Its integrated NCI 2.0 stack, ISO/IEC 14443A/B/T4T compliance, and dynamic power control ensure alignment with NFC Forum Digital Protocol and Test Specifications - subject to final system-level validation.
