Product details
Overview
PN7412AUHN from NXP Semiconductors is a 32-bit Arm Cortex-M0 NFC microcontroller with 160 kB Flash, 12 kB SRAM, and integrated ISO/IEC 7816-3&4 UART contact smart card interface - but no contactless frontend. It operates at up to 20 MHz and supports Class A/B/C cards at 1.8 V, 3 V, and 5 V for secure dual-interface reader designs requiring only contact functionality.
For engineers reviewing the PN7412AUHN datasheet, PN7412AUHN pinout, PN7412AUHN application, or PN7412AUHN equivalent, this device serves as a dedicated contact-only smart card controller with thermal/short-circuit protection, automatic activation/deactivation, and UART-based host interfacing - ideal for EMV-compliant payment terminals, physical access readers, and banking peripherals where RF complexity is excluded.
Technical Context
The PN7412AUHN implements a full ISO/IEC 7816-3&4 UART interface with variable baud rate control, character-level error management for T=0 protocols, and guard time programming. Its contact frontend delivers DC-to-DC conversion for Class A support starting at 3 V and Class B at 2.7 V, plus ESD protection >12 kV and supply supervision.
Unlike PN7462 variants, PN7412AUHN omits the CLIF (contactless interface frontend), eliminating antenna drivers (TX1/TX2), RF pins (ANT1/ANT2), and associated LDOs (TVDD_IN/TVDD_OUT). Its block diagram confirms absence of CLIF, CRC coprocessor usage for contact-only protocols, and reliance on HSUART/I2C/SPI for host communication without USB PHY.

Equivalent & Alternatives
The following parts are listed as comparable options for similar contact smart card controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7462AUHN | Includes full CLIF (contactless frontend), 13.56 MHz RF frontend, antenna drivers, and TX_LDO - adds 30+ pins and RF design complexity. | Required for dual-interface (contact + contactless) readers; unsuitable when only contact functionality is needed due to increased layout area and RF compliance overhead. | Select PN7462AUHN only if NFC tag emulation, P2P, or card emulation features are required alongside contact support. |
| SLB9670 | Trusted Platform Module (TPM) 2.0 compliant secure microcontroller with ISO/IEC 7816 interface - lacks dedicated smart card voltage generation and EMV-specific timing controls. | Targeted at platform security (attestation, key storage), not transactional smart card readers; requires external voltage regulation and protocol stack implementation. | Choose SLB9670 for root-of-trust integration in host systems, not as a drop-in replacement for dedicated EMV reader controllers. |
Compared with PN7462AUHN, PN7412AUHN reduces pin count, eliminates RF design constraints, and lowers power consumption - making it optimal for cost-sensitive, space-constrained contact-only readers. Versus SLB9670, it delivers turnkey EMV contact compliance with integrated voltage generation and protocol acceleration.

FAQ
Does PN7412AUHN support contactless NFC functionality?
No, PN7412AUHN does not include a contactless interface frontend (CLIF). Unlike PN7462AUHN, it lacks antenna drivers (TX1/TX2), RF pins (ANT1/ANT2), and associated LDOs. It is strictly a contact-only ISO/IEC 7816 smart card controller. PN7412AUHN is intended for applications where NFC capability is unnecessary or handled externally.
What smart card voltage classes does PN7412AUHN support?
PN7412AUHN supports Class A (5 V), Class B (3 V), and Class C (1.8 V) smart cards via its integrated DC-to-DC converter and programmable VCC output.
