NXP Semiconductors PN5190B2HN/C131Y

Overview

PN5190B2HN/C131Y from NXP Semiconductors is a high-power NFC frontend IC for 13.56 MHz contactless communication, supporting ISO/IEC 14443-A/B, FeliCa, ISO/IEC 15693, ISO/IEC 18000-3 Mode 3, NFC-IP1/2, and MIFARE card family R/W - all with hardware-accelerated crypto. It delivers up to 2.3 W RF output power, integrates DC-DC (2.8–6.0 V), and operates with ultra-low-power card detection (22 μA avg) for battery-powered payment terminals and access readers.

For engineers reviewing the PN5190B2HN/C131Y datasheet, PN5190B2HN/C131Y pinout, PN5190B2HN/C131Y application, or PN5190B2HN/C131Y equivalent, key selection considerations include firmware version (v3.2 preloaded), VFLGA40 package (5 mm × 5 mm × 0.8 mm, 40-pin), SPI interface (15 Mbit/s), integrated TX LDO + DC-DC, and support for autonomous DPC2.0 and AWC without host intervention.

Technical Context

The PN5190B2HN/C131Y implements a fully integrated analog front-end with dual TX outputs (TX1/TX2), differential RX inputs (RXP/RXN), and on-chip PLL clock generation (27.12 MHz crystal or 24/32/48 MHz external reference). Its receiver chain includes automatic RF attenuator and true baseband amplifier (BBA) for extended range in noisy environments.

Dynamic Power Control 2.0 uses real-time transmitter current measurement and sub-1 ms regulation to autonomously adjust TX_LDO voltage (100 mV granularity) and DC-DC output, minimizing chip power dissipation during antenna detuning. Adaptive Wave Shape Control (AWC) dynamically corrects RF waveform distortion without host involvement, enabling robust operation across diverse antenna load conditions.

FAQ

What firmware version is preloaded on PN5190B2HN/C131Y?

PN5190B2HN/C131Y ships with firmware version 3.2 preloaded. This version includes Dynamic Power Regulation (DPR), enhanced ULPCD current efficiency, LPCD-with-Autocoll event support, and CTS fast configuration. Firmware cannot be downgraded, and encrypted firmware updates are supported via HDLL commands.

Does PN5190B2HN/C131Y support MIFARE Classic authentication in hardware?

Yes, PN5190B2HN/C131Y includes hardware-accelerated crypto engines licensed for NXP MIFARE Classic, Plus, Ultralight, and DESFire families. It implements R/W functionality for all MIFARE product-based cards with full intellectual-property licensing rights for ISO/IEC 14443-A and Innovatron ISO/IEC 14443-B protocols.

What is the difference between LPCD and ULPCD modes on PN5190B2HN/C131Y?

LPCD uses I/Q channel analysis for maximum detection range and sensitivity, while ULPCD uses amplitude-only detection to achieve 22 μA average current. ULPCD reserves GPIO3 exclusively for abort functionality and disables the DC-DC; LPCD allows full feature use including DC-DC and higher detection reliability in noisy environments.

Can PN5190B2HN/C131Y operate without an external 27.12 MHz crystal?

Yes. PN5190B2HN/C131Y supports alternative clock sources: 24 MHz, 32 MHz, or 48 MHz external clocks configured via EEPROM register CLK_INPUT_FREQ (0012h). The internal PLL generates the required 27.12 MHz RF clock, eliminating the need for a dedicated crystal in systems already providing one of these frequencies.

What package type and dimensions does PN5190B2HN/C131Y use?

PN5190B2HN/C131Y uses the VFLGA40 package: very thin fine-pitch land grid array with 40 terminals, 0.4 mm pitch, and 5 mm × 5 mm × 0.8 mm body. It includes an exposed thermal pad requiring solder connection to PCB ground plane for thermal management and EMI control.
