Product details
Overview
PN7642EV/C100K from NXP Semiconductors is a single-chip NFC controller integrating an Arm Cortex-M33 MCU (45 MHz), hardware-accelerated symmetric/asymmetric cryptography, and a high-power 2.0 W NFC frontend supporting ISO14443-A/B, FeliCa, ISO15693, and MIFARE card emulation. It delivers secure contactless authentication for access control terminals with dynamic power control (DPC 2.0), adaptive waveshape control (AWC), and ultra-low-power card detection (ULPCD) consuming only 22 μA average current.
For engineers reviewing the PN7642EV/C100K datasheet, PN7642EV/C100K pinout, PN7642EV/C100K application, or PN7642EV/C100K equivalent, this page provides verified technical context on its NFC reader/writer modes, security subsystem architecture, transmitter power regulation, receiver sensitivity (10-bit ADC + true AGC), and firmware-upgrade pathways via USB, SPI, I2C, or NFC itself.
Technical Context
The PN7642EV/C100K implements a fully integrated NFC frontend with autonomous DPC 2.0 using true current measurement and 100 mV granularity VDDPA LDO voltage control, enabling real-time RF output adaptation without CPU intervention. Its receiver employs true automatic gain control (AGC), internal voltage divider, and 10-bit ADC to maintain optimal SNR across noisy environments including TFT displays and DC-DC converters.
Security is enforced through dedicated hardware accelerators for AES-128/256, SHA-256, RSA, ECDSA, and EdDSA, coupled with a secure key store for symmetric keys and key transfer unit isolating crypto operations from CPU access. The Cortex-M33 core runs at 45 MHz with 180 kB user flash and 20 kB user RAM, supporting field firmware updates over USB, SPI, I2C, I3C, UART, or NFC.

The PN7642EV/C100K serves as a complete NFC controller IC that integrates an Arm Cortex-M33 microcontroller, NFC frontend, and security subsystem. It operates as both a reader/writer (PCD) supporting ISO14443-A/B, FeliCa, and ISO15693, and as a card emulator (PICC) for ISO14443-A. Its autonomous DPC 2.0 and AWC features enable robust RF performance without host intervention, making PN7642EV/C100K ideal for standalone access readers and secure authentication modules.
Does the PN7642EV/C100K support firmware updates in the field, and how is it performed?
Yes, the PN7642EV/C100K supports secure field firmware updates via USB, SPI, I2C, I3C, UART, or NFC interfaces. The process uses a dedicated command set followed by hardware reset to enter secure download mode. For PN7642EV/C100K specifically, firmware download mode is activated by asserting the DWL_REQ pin, enabling authenticated updates without requiring external programming hardware - a critical capability for deployed PN7642EV/C100K units in remote locations.
What security certifications apply to the PN7642EV/C100K?
The PN7642EV/C100K is certified to SESIP Level 2 and NFC Forum (reader device and card emulation). These certifications validate its resistance to side-channel attacks, secure key storage implementation, and compliance with NFC Forum's interoperability and security requirements. The hardware-accelerated crypto engines and isolated key transfer unit ensure that AES-128/256, SHA-256, ECDSA, and Ed25519 operations meet the protection profiles defined in SESIP L2 - confirming PN7642EV/C100K's suitability for government ID and payment applications.
How does the PN7642EV/C100K manage power efficiency in battery-powered devices?
The PN7642EV/C100K achieves ultra-low power operation through hardware-accelerated ULPCD consuming just 22 μA average current during polling, combined with hard power-down mode drawing only 40 μA. Its integrated DC-DC boost converter sustains 2.0 W transmitter output from a dropping 3.3 V battery supply, while DPC 2.0 dynamically reduces VDDPA voltage to minimize dissipation during antenna loading. This multi-layered approach ensures PN7642EV/C100K delivers multi-year battery life in portable readers without sacrificing RF performance.
