Product details
Overview
PNEV7462C from NXP Semiconductors is a 32-bit Arm Cortex-M0 NFC microcontroller with integrated contactless frontend, ISO/IEC 7816 contact interface, and 160 kB Flash/12 kB SRAM. It operates at up to 20 MHz, supports EMV-compliant 13.56 MHz RF communication (up to 848 kbit/s), and enables dual-interface smart card readers in physical access control and payment terminals.
For engineers reviewing the PNEV7462C datasheet, PNEV7462C pinout, PNEV7462C application, or PNEV7462C equivalent, this page delivers verified technical context, validated pin functions, confirmed NFC and contact interface capabilities, and real-world design implications for secure embedded reader systems.
Technical Context
The PNEV7462C integrates a high-power NFC frontend supporting ISO/IEC 14443 A/B, MIFARE Crypto1, ISO/IEC 15693, and NFC Forum tag types 1–5, with Dynamic Power Control and Adaptive Wave/Range Control for robust field management. Its contact interface complies with ISO/IEC 7816-3&4 UART and supports Class A/B/C cards at 1.8 V, 3 V, and 5 V with thermal/short-circuit protection.
It features a dedicated 27.12 MHz crystal oscillator, USB 2.0 full-speed host interface, HSUART up to 1.288 Mbit/s, SPI master up to 6.78 Mbit/s, and four general-purpose timers - all managed by an Arm Cortex-M0 core with NVIC, SWD debug, and integrated PMU for multi-mode power optimization.

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; identical memory, NFC, and contact interface specs; same pinout and thermal profile. | Direct drop-in replacement with identical mechanical and electrical footprint - suitable for new designs requiring NXP's standard production variant. | Select PN7462AUHN when sourcing from authorized distributors with standard lead times; PNEV7462C is typically reserved for EVB or pre-release evaluation use. |
| PN7362AUHN | No contact interface; 160 kB Flash/12 kB SRAM; same HVQFN64 package but missing SCVDD, SAP, AUX1–2, CLK, RST, IO pins. | Limited to contactless-only applications (e.g., NFC tag readers, sensor hubs) - cannot support dual-interface or smart card reader use cases. | Choose PN7362AUHN only if contact interface is unnecessary; PNEV7462C provides full dual-interface capability required for payment and access control. |
Compared with PN7462AUHN, PNEV7462C offers identical functional and pin-compatible operation but targets evaluation use; versus PN7362AUHN, it adds full ISO/IEC 7816 support and associated pins - making it the sole option among these three for certified dual-interface reader development.

FAQ
What is the primary function of the PNEV7462C in an embedded system?
The PNEV7462C serves as a fully integrated dual-interface reader controller, executing NFC and ISO/IEC 7816 protocols simultaneously while running application firmware on its Arm Cortex-M0 core. It handles RF field generation, contact card voltage regulation, cryptographic acceleration, and host communication - eliminating the need for multiple discrete ICs in secure reader designs. The PNEV7462C is engineered to reduce system complexity and certification burden in payment and access control applications.
Does the PNEV7462C support EMV contactless certification out of the box?
Yes, the PNEV7462C's integrated NFC frontend meets EMVCo contactless Level 1 RF requirements without external active components. Its Adaptive Wave Control, Dynamic Power Control, and built-in compliance with ISO/IEC 14443 A/B ensure baseline RF interoperability. However, full end-product EMV certification requires validation of the complete system - including antenna design, shielding, and firmware stack - not just the PNEV7462C alone.
Can the PNEV7462C operate without an external crystal?
No - the PNEV7462C requires a 27.12 MHz crystal connected to XTAL1 and XTAL2 pins for accurate NFC carrier frequency generation and system timing. While it includes internal HFO (20 MHz) and LFO (365 kHz) oscillators for low-power modes and watchdog timing, the crystal is mandatory for NFC operation and USB synchronization. Omitting it will disable contactless communication and USB functionality.
How many general-purpose I/O pins does the PNEV7462C provide, and what are their key capabilities?
The PNEV7462C provides up to 21 general-purpose I/O pins (GPIO1–GPIO21), with GPIO1–GPIO12 supporting edge- and level-sensitive interrupts. All GPIOs are configurable with programmable pull-up/pull-down resistors and support alternate functions such as SPI, I²C, UART, and timer capture/compare. This flexibility allows direct interfacing with LEDs, buttons, sensors, and external peripherals without additional level-shifting or glue logic.
Is the PNEV7462C pin-compatible with other members of the PN7462 family?
Yes - the PNEV7462C shares the same HVQFN64 pinout as PN7462AUHN and PN7412AUHN, including identical placement of power, RF, contact interface, debug, and GPIO pins. This enables hardware reuse across variants. However, functional differences exist: PN7412AUHN lacks the contactless frontend (no ANT1/ANT2/TVDD_IN), and PN7362AUHN omits both contact and contactless interfaces - so pin compatibility does not imply functional interchangeability.
