Overview
The PN7412AUHN/C300Y is a 32-bit NFC microcontroller based on the ARM Cortex-M0 core, operating at frequencies up to 20 MHz. It integrates 160 kB of Flash memory and 12 kB of SRAM data memory within an HVQFN64 package. The device features an integrated contact smart card reader interface compliant with ISO/IEC 7816 standards, supporting Class A, B, and C cards. Unlike other family members, it lacks a contactless RF interface. Key peripherals include USB 2.0 full-speed, HSUART, SPI, I2C, four general-purpose timers, a CRC coprocessor, and a random number generator.
Feature Summary
- Integrated contact smart card reader frontend supporting ISO/IEC 7816-3 & -4 protocols
- Supports Class A (5 V), Class B (3 V), and Class C (1.8 V) smart cards
- Includes DC-to-DC converter for Class A/B support and thermal/short-circuit protection
- Features ISO/IEC 7816 UART interface for connecting slot extenders like TDA8026
Applications
- Dual interface smart card readers
- Contact-only smart card readers
- Physical access control systems
- High integration devices requiring secure contact communication
Procurement Notes
Verify that the specific application requires a contact-only interface, as this model excludes the contactless NFC radio found in PN7462 variants. Confirm package availability in HVQFN64 format and ensure design compatibility with the 9 × 9 × 0.85 mm body dimensions specified for the SOT804-4 package.
Selection Notes
Select PN7412AUHN when a contact smart card reader function is needed without the cost or complexity of an NFC RF frontend. Ensure the system design accounts for the absence of ANT1/ANT2 pins and TVDD_IN connections required for contactless operation in other family members.
Part Context
This component belongs to the PN7462 family of NFC Cortex-M0 microcontrollers. While sharing the same CPU core, memory architecture, and peripheral set as the PN7462AUHN, the PN7412AUHN is specifically differentiated by the omission of the integrated contactless interface frontend, positioning it for dedicated contact-based applications.
Replacement Considerations
PN7462AUHN offers identical functionality plus integrated contactless NFC capabilities. PN7362AUHN provides similar specifications but lacks both the contact interface and the ISO/IEC 7816 UART interface.
