FAQ
What is the maximum RF data rate supported by PN7462AUHN/C300E in contactless mode?
The PN7462AUHN/C300E supports a maximum contactless data transfer rate of 848 kbit/s in high-speed NFC modes, compliant with NFC Forum specifications and EMV contactless Level 1 RF requirements. This rate is achieved using its integrated high-power NFC frontend with Adaptive Wave Control and Dynamic Power Control, ensuring reliable communication even under marginal coupling conditions. The PN7462AUHN/C300E maintains this performance without external active components.
Does PN7462AUHN/C300E support ISO/IEC 7816-3 and -4 for contact smart cards?
Yes, PN7462AUHN/C300E includes a fully integrated ISO/IEC 7816-3&4 UART interface supporting Class A (5 V), Class B (3 V), and Class C (1.8 V) smart cards. It provides hardware-level current limiting, short-circuit detection, ESD protection (>12 kV), and automatic activation/deactivation sequences - all implemented on-die without external components. The PN7462AUHN/C300E also supports synchronous card protocols and auxiliary slot extension via TDA8026.
What power supply configurations are required for PN7462AUHN/C300E's NFC and contact interfaces?
PN7462AUHN/C300E requires three distinct supply domains: VBUS (3–5.5 V) for the MCU core, VBUSP (3–5.5 V) for the contact interface, and TVDD_IN (3–5.5 V) for the NFC frontend. Its integrated TX LDO generates TVDD_OUT at selectable voltages (3.0/3.3/3.6/4.5/4.75 V) to drive the antenna. For USB operation, PVDD_IN must be regulated to 3.0–3.6 V per USB specification. The PN7462AUHN/C300E manages all domains internally via its PMU.
Can PN7462AUHN/C300E operate in low-power modes while maintaining NFC field detection?
Yes, PN7462AUHN/C300E supports wake-up from hard power-down and standby modes via RF field detection, enabling ultra-low-power listening states. In hard power-down mode (12 µA), it retains the ability to detect an incoming 13.56 MHz field and autonomously transition to active mode within microseconds. This capability is essential for battery-powered readers requiring long idle periods while remaining responsive to card presence - a core feature of the PN7462AUHN/C300E architecture.
What debug and programming interfaces does PN7462AUHN/C300E provide?
PN7462AUHN/C300E provides Serial Wire Debug (SWD) via SWDIO and SWDCLK pins for full JTAG-equivalent debugging, flash programming, and secure firmware updates. It also includes a 40 kB boot ROM with USB mass storage primary boot loader, allowing drag-and-drop firmware updates via standard USB cable without additional tools. The PN7462AUHN/C300E supports secure boot and encrypted firmware loading through its integrated cryptographic peripherals.
