Product details
Overview
PN7462AUEV from NXP Semiconductors is a 32-bit Arm Cortex-M0 NFC microcontroller in VFBGA64 package, operating up to 20 MHz with 160 kB Flash, 12 kB SRAM, and 4 kB EEPROM. It integrates a high-power 13.56 MHz contactless frontend supporting EMV-compliant card emulation (ISO/IEC 14443-A/B), P2P, and full NFC Forum tag types - deployed in USB NFC readers and payment terminals.
For engineers reviewing the PN7462AUEV datasheet, PN7462AUEV pinout, PN7462AUEV application, or PN7462AUEV equivalent, key selection criteria include its VFBGA64 footprint, absence of contact smart card interface, integrated ISO/IEC 7816-3&4 UART auxiliary interface, and support for USB 2.0 full-speed host connectivity with SWD debug.
Technical Context
The PN7462AUEV implements a dedicated Arm Cortex-M0 core with NVIC, 24-bit SysTick, and clock management enabling low-power operation across standby, hard power-down, and USB suspend modes. Its integrated NFC frontend includes Adaptive Wave Control (AWC), Dynamic Power Control (DPC), and compliance with EMV contactless protocol specification.
It features dual master interfaces (SPI up to 6.78 Mbit/s, Fast-mode Plus I2C), four general-purpose timers, CRC coprocessor, random number generator, and crystal oscillator at 27.12 MHz with dedicated 48 MHz USB PLL. The device supports RF supply via external source or integrated TX LDO configurable at 3.0–4.75 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7462AUHN | HVQFN64 package; includes full contact smart card interface (ISO/IEC 7816) and thermal/short-circuit protection on card contacts. | Suitable for dual-interface (contact + contactless) smart card readers requiring physical card insertion. | Select PN7462AUHN if contact interface and HVQFN thermal performance are required; PN7462AUEV is preferred for pure contactless designs with space-constrained layouts. |
| PN7362AUEV | VFBGA64 package; 160 kB Flash but no ISO/IEC 7816-3&4 UART interface - lacks auxiliary contact slot extension capability. | Targeted at cost-optimized NFC-only applications where multi-slot contact extension is unnecessary. | Choose PN7362AUEV only when ISO/IEC 7816 UART auxiliary interface is not needed; PN7462AUEV adds critical flexibility for scalable reader architectures. |
Compared with PN7462AUHN, PN7462AUEV removes contact interface circuitry to reduce die size and power, while retaining identical NFC performance and auxiliary UART for slot expansion; versus PN7362AUEV, it adds the ISO/IEC 7816-3&4 UART essential for multi-card-reader systems.

What package type and dimensions does the PN7462AUEV use?
The PN7462AUEV uses a VFBGA64 package: plastic very thin fine-pitch ball grid array with 64 balls, 4.5 mm × 4.5 mm body size, and 0.5 mm ball pitch. Its height is 0.80 mm, and it complies with JEDEC standards for reflow soldering. This compact footprint is optimized for space-constrained portable NFC readers and wearable authentication devices.
How does the PN7462AUEV achieve EMV contactless compliance?
The PN7462AUEV achieves EMV contactless Level 1 compliance through its integrated high-power NFC frontend, which includes Adaptive Wave Control (AWC), Dynamic Power Control (DPC), and Adaptive Range Control (ARC). These features maintain precise field strength, modulation depth, and timing margins across temperature and supply variations - eliminating the need for external RF tuning components and simplifying certification testing for PN7462AUEV-based designs.
What debug and programming interfaces are available on the PN7462AUEV?
The PN7462AUEV provides Serial Wire Debug (SWD) via dedicated SWDIO and SWDCLK pins for full firmware debugging, flash programming, and real-time trace.
