Product details
Overview
PN7161A1EV/C100Y from NXP Semiconductors is a Near Field Communication (NFC) controller IC with integrated NCI 2.0 interface, firmware version 12.50.05, and VFBGA64 package. It supports ISO/IEC 14443A/B, ISO/IEC 15693, MIFARE, FeliCa, and NFC Forum T4T/T5T protocols, delivers 1.3 W transmitter output power, and achieves 20 mV(p-p) card-mode receiver sensitivity for secure contactless transactions in mobile and portable devices.
For engineers reviewing the PN7161A1EV/C100Y datasheet, PN7161A1EV/C100Y pinout, PN7161A1EV/C100Y application, or PN7161A1EV/C100Y equivalent, key selection criteria include ECP support for Apple ecosystem integration, autonomous card emulation during host shutdown, low-power polling loop current of 100 μA, and compatibility with I²C host interface at 3.3 V supply.
Technical Context
The PN7161A1EV/C100Y implements an ARM Cortex-M0 core with 128 kB ROM, 28 kB EEPROM, and 8 kB SRAM, executing NXP's proprietary firmware to manage NFC protocol stacks and RF front-end control. Its integrated power management unit enables direct battery connection (2.8–5.5 V), Hard Power Down mode (<16 μA), and Standby state wake-up via RF field or host interface signals.
This device features a dual-antenna driver architecture (TX1/TX2), independent LMA phase adjustment (5° steps for Type A/B/F), Enhanced Dynamic Load Modulation Amplitude (DLMA), and dynamic power control compliant with NFC Forum and EMVCo standards - all enabled by its dedicated RF front-end supporting active load modulation and small-form-factor antenna operation.

FAQ
What distinguishes PN7161A1EV/C100Y from PN7160A1EV/C100Y?
PN7161A1EV/C100Y includes "Enhanced Contactless Polling" (ECP) authorized by Apple, confirmed by model ID 0x71 in the CORE_RESET_NTF response. PN7160A1EV/C100Y has model ID 0x61 and lacks ECP. Both share identical VFBGA64 packaging, I²C interface, firmware version 12.50.05, and electrical specifications - making them pin-compatible but functionally differentiated for iOS ecosystem integration.
Does PN7161A1EV/C100Y support autonomous card emulation without host processor involvement?
Yes. PN7161A1EV/C100Y supports Autonomous mode where the host sets the AutoMode bit, allowing full card emulation (including NDEF content serving) while the main system is powered down. This relies on internal SRAM and EEPROM, wake-up via RF field or IRQ, and operates at 100 μA in low-power polling loop - verified in Section 11.1.1 of the datasheet.
What is the minimum supply voltage required for PN7161A1EV/C100Y transmitter operation?
PN7161A1EV/C100Y requires VBAT ≥ 2.8 V for reader, active initiator, and active target modes - including full 1.3 W transmitter output. The VDD(TX) supply can range from 2.7 V to 5.25 V, but stable operation below 2.8 V VBAT is not supported for RF transmission, as specified in Table 1 (Quick reference data).
Can PN7161A1EV/C100Y be used with SPI instead of I²C?
No. PN7161A1EV/C100Y is configured for I²C interface only, indicated by the "A" in position 7 of the part number (per Table 2: x = A for I²C, B for SPI). SPI variants use part numbers like PN7161B1EV/C100Y. Pin functions I2C_ADR0/SPI_NSS and I2C_SDA/SPI_MISO are multiplexed, but firmware and hardware configuration are fixed per orderable variant.
Is the VFBGA64 package of PN7161A1EV/C100Y RoHS and halogen-free compliant?
Yes. Per Table 5 and Table 6, the marking code includes "D" in Line C (VFBGA64) or Line C (HVQFN40), indicating Dark Green RoHS compliance with no halogen or antimony. The manufacturing code also confirms full RoHS and green material compliance - consistent across all PN7161A1EV/C100Y production lots.
