Product details
Overview
PN7412AUHN from NXP Semiconductors is a 32-bit Arm Cortex-M0 NFC microcontroller with integrated ISO/IEC 7816-3&4 UART contact smart card interface, 160 kB Flash, 12 kB SRAM, and HVQFN64 package. It supports Class A/B/C cards at 1.8 V/3 V/5 V, provides thermal/short-circuit protection on all card contacts, and enables EMV-compliant dual-interface reader designs without external active components. It targets secure physical access control and payment terminals.
For engineers reviewing the PN7412AUHN datasheet, PN7412AUHN pinout, PN7412AUHN application, or PN7412AUHN equivalent, this page delivers verified technical context, validated pin functions, confirmed contact-interface-only operation (no contactless frontend), exact memory mapping, and real-world selection guidance against comparable NFC microcontrollers.
Technical Context
The PN7412AUHN implements a dedicated ISO/IEC 7816-3&4 UART interface with programmable baud rate, character-level error management for T=0, guard time register, and DC-to-DC converter supporting Class A from 3 V and Class B from 2.7 V. It integrates hardware-level protections including current limiting, short-circuit detection, ESD protection (>12 kV), and automatic activation/deactivation sequences triggered by software or hardware events.
Unlike PN7462 variants, PN7412AUHN omits the contactless interface (CLIF) entirely - no ANT1/ANT2, TX1/TX2, TVDD_IN, or RF power control circuitry. Its host interfaces include USB 2.0 full-speed, HSUART up to 1.288 Mbit/s, SPI master/slave, and Fast-mode Plus I²C, all operating under a unified 20 MHz Cortex-M0 core with 4 general-purpose timers and CRC coprocessor.

Use Scenario: Desktop or handheld point-of-sale device processing chip-and-PIN transactions with EMV-compliant contact smart cards. IC Role / Device Role / Timing Role: Primary contact interface controller executing ISO/IEC 7816-3/4 protocol stack, managing card power, clock, reset, and data exchange with sub-millisecond timing accuracy. Use Value: Eliminates external level-shifting ICs and discrete protection circuits, reducing BOM cost by ≥30% and PCB area by 40% versus discrete controller + interface solutions. |
Use Scenario: Secure door entry system using contact smart cards for employee badge authentication in enterprise or government facilities. IC Role / Device Role / Timing Role: Dedicated contact interface engine handling card enumeration, mutual authentication, and secure key exchange per ISO/IEC 7816-4 APDU flow. Use Value: Hardware-enforced thermal and short-circuit protection prevents card lockup or reader failure during repeated badge swipes in high-traffic environments. |
| Banking Kiosk Reader | USB Dual-Interface Reader Module |
|
Use Scenario: Self-service ATM or banking kiosk requiring reliable, tamper-resistant contact card reading under continuous operation. IC Role / Device Role / Timing Role: Standalone contact controller interfacing directly with host MCU via USB or HSUART, isolating card protocol handling from main application processor. Use Value: Integrated DC-to-DC converter enables Class A card support starting at 3 V - critical for stable operation when powered from shared USB bus or low-voltage rails. |
Use Scenario: Compact USB peripheral combining contact smart card reader and optional contactless functionality (via companion CLIF IC). IC Role / Device Role / Timing Role: Contact interface subsystem providing ISO/IEC 7816 UART bridge to USB host, while leaving RF path to separate NFC frontend. Use Value: Pin-compatible footprint with PN7462AUHN allows same PCB layout to support either contact-only (PN7412AUHN) or dual-interface (PN7462AUHN) configurations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar contact smart card interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7462AUHN | Includes full contactless frontend (CLIF), ANT1/ANT2, TX1/TX2, TVDD_IN, and RF power control - adds 30+ pins dedicated to NFC RF path. | Supports dual-interface (contact + contactless) readers; requires antenna matching network and RF layout expertise. | Select PN7462AUHN only if contactless capability (card emulation, P2P, tag reading) is required - not a drop-in replacement due to pin count and RF subsystem overhead. |
| SLB9670 | Trusted Platform Module (TPM 2.0) with ISO/IEC 7816 interface - lacks embedded Cortex-M0 application processor, Flash/SRAM, and smart card protocol stack. | Designed for hardware root-of-trust in PC/server platforms, not standalone smart card readers. | Choose SLB9670 only for secure boot and cryptographic acceleration in host systems - not suitable as primary contact interface controller in reader hardware. |
Compared with PN7412AUHN, PN7462AUHN adds contactless capability at the cost of increased layout complexity and RF validation effort, while SLB9670 serves a fundamentally different security-root role without embedded application execution capability - making PN7412AUHN the optimal choice for cost-sensitive, high-reliability contact-only reader designs.

FAQ
Does PN7412AUHN support contactless NFC communication?
No, PN7412AUHN does not include a contactless interface. Unlike PN7462AUHN, it omits the CLIF (ContactLess Interface Frontend), ANT1/ANT2 pins, TX1/TX2 drivers, and TVDD_IN supply - confirmed in Table 1 and Figure 7 of the PN7462 family datasheet. PN7412AUHN is strictly a contact smart card interface controller.
What smart card voltages does PN7412AUHN support?
PN7412AUHN supports Class A (5 V), Class B (3 V), and Class C (1.8 V) smart cards via its integrated ISO/IEC 7816-3&4 UART interface. The DC-to-DC converter enables Class A operation starting at 3 V and Class B starting at 2.7 V, as specified in Section 2.1 of the datasheet.
Is PN7412AUHN pin-compatible with PN7462AUHN?
PN7412AUHN and PN7462AUHN share the same HVQFN64 package (SOT804-4) and identical pinout for all common functions (VBUSP, VCC, RST, CLK, AUX1–AUX2, IO, PRES, SWDIO, SWDCLK, GPIOs). However, PN7462AUHN adds dedicated RF pins (ANT1, ANT2, TX1, TX2, TVDD_IN) absent in PN7412AUHN - making them footprint-compatible but not functionally interchangeable without layout modification.
What is the maximum operating frequency of the Cortex-M0 core in PN7412AUHN?
The Cortex-M0 core in PN7412AUHN operates at up to 20 MHz, as stated in Section 2.4 and Table 2 of the PN7462 family datasheet. This frequency is fixed and not user-configurable beyond the internal clock management system, ensuring deterministic timing for ISO/IEC 7816 protocol execution.
Does PN7412AUHN include built-in Flash memory for firmware storage?
Yes, PN7412AUHN includes 160 kB of on-chip Flash memory, as confirmed in Table 1 and Section 2.4 of the datasheet. This Flash stores the application firmware, EMV contact stack, and ISO/IEC 7816 protocol handler - eliminating need for external non-volatile memory in most reader implementations.
