Product details
Overview
PN7642EV/C101Y 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-performance 13.56 MHz NFC frontend supporting ISO14443-A/B, FeliCa, ISO15693, and card emulation. It delivers 2.0 W transmitter output power with Dynamic Power Control 2.0 and operates across –40 °C to +85 °C with full RF power for secure access terminals and payment readers.
For engineers reviewing the PN7642EV/C101Y datasheet, PN7642EV/C101Y pinout, PN7642EV/C101Y application, or PN7642EV/C101Y equivalent, this page provides verified technical context, validated VFBGA64 pin mapping, confirmed firmware version (v2.00 with pinless-download mode), real-world NFC protocol support (including ECP 2.0 and NTAG 5 at 212 kbit/s), and security-critical parameters like SESIP L2 certification and secure key store architecture.
Technical Context
The PN7642EV/C101Y implements a tightly coupled Arm Cortex-M33 core with integrated NFC analog front-end, where RF signal generation and demodulation are handled entirely on-die without host intervention. Its transmitter uses dynamic power control (DPC 2.0) with true current measurement and 100 mV granularity voltage regulation, while adaptive waveshape control (AWC) maintains waveform compliance under antenna detuning.
Security is enforced via dedicated hardware accelerators for AES-128/256, SHA-256, RSA, ECC (including Ed25519), and a secure key store with key transfer unit bypassing CPU involvement. The receiver employs true AGC, 10-bit ADC, and RSSI-based automatic gain adjustment to sustain robust communication in noisy environments (e.g., near TFT displays or DC-DC converters).

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7642EV/C100 | Firmware v1.00; download mode requires DWL_REQ pin assertion - adds external pin dependency and layout complexity | Lacks pinless-download capability; not suitable for sealed or space-constrained designs | Select only when legacy firmware compatibility or cost-sensitive non-field-upgradeable deployments are required |
| PN7642EV/C102 | Firmware v3.00; includes enhanced ECP 2.0 features and updated cryptographic library - backward-compatible but not identical feature set | Supports newer NFC Forum specifications and additional curve support (SECP384, Brainpool P384r1) | Prefer for new designs targeting long-term roadmap alignment and future-proofed security compliance |
Compared with PN7642EV/C101Y, the C100 variant requires hardware pin control for firmware updates and lacks pinless-download flexibility, while the C102 offers expanded crypto agility and specification coverage - making C101Y the optimal balance of field-upgradability, certification readiness, and deployment maturity.

FAQ
What firmware version ships with PN7642EV/C101Y?
PN7642EV/C101Y ships pre-programmed with firmware version 2.00, which enables pinless-download mode by default - eliminating the need for external DWL_REQ pin assertion during firmware updates. This simplifies PCB layout and improves reliability in sealed enclosures. The firmware supports all documented NFC protocols, cryptographic algorithms, and power management features specified in the Rev. 3.9 datasheet dated 16 April 2026.
Does PN7642EV/C101Y support ISO14443-B card emulation?
No, PN7642EV/C101Y supports ISO14443-A card emulation (PICC mode) only, as confirmed in Section 2.1.8 and Table 1 of the datasheet. It does not implement ISO14443-B card emulation. However, it fully supports ISO14443-B reader/writer (PCD) mode up to 848 kbit/s for interoperability with B-type cards and devices. This asymmetric capability aligns with its target use cases in secure access and payment where A-type emulation suffices for credential presentation.
How does PN7642EV/C101Y achieve 2.0 W RF output with a 3.3 V supply?
PN7642EV/C101Y achieves 2.0 W RF output using its integrated step-up DC-DC converter, which boosts the 3.3 V system supply to up to 6.0 V for the transmitter power amplifier (VDDPA). This is enabled by the VDDBOOST and BOOST_LX pins, and regulated autonomously by Dynamic Power Control 2.0. The DC-DC clock is synchronized with the receiver clock to prevent noise coupling - a key differentiator from external boost converters that degrade RF sensitivity.
Is PN7642EV/C101Y pin-compatible with other PN7642 variants like C100 or C102?
Yes, PN7642EV/C101Y is mechanically and electrically pin-compatible with PN7642EV/C100 and PN7642EV/C102 - all use the identical VFBGA64 package (SOT1307-2) with matching ball pitch, footprint, and pin functions. Differences are limited to pre-flashed firmware version and factory-default transport keys; no PCB redesign is needed when migrating between these variants. Thermal and electrical behavior remains consistent across all three versions.
What certifications apply to PN7642EV/C101Y?
PN7642EV/C101Y carries SESIP Level 2 certification for secure element functionality and NFC Forum certification for both reader device and card emulation modes. These certifications were validated against firmware v2.00 and confirm compliance with EMVCo 3.0, ISO/IEC 14443, ISO/IEC 15693, and NFC Forum Digital Protocol standards. Certification documentation is maintained by NXP and accessible under NDA for qualified customers.
