PN7642EV - NFC Reader + Arm Cortex-M33 MCU 64-VFBGA | NXP
MPN： PN7642EV ✓ 啟用中PN7642EV 概覽
An NFC controller IC is a single-chip device that manages contactless communication according to proximity-coupling standards such as ISO 14443-A/B, ISO 15693, FeliCa, and NFC Forum protocols. Within the system hierarchy, it sits between the RF antenna front end and the host application layer, replacing the classic three-chip combination of a dedicated NFC reader IC, a general-purpose MCU, and a discrete Secure Element with one integrated solution.
Key features include the integrated Arm Cortex-M33 core running application firmware from 180 kB of on-chip flash, full reader/writer (PCD) support for ISO14443-3/4 A/B, ISO15693 / ISO18000-3 mode 1, FeliCa, ISO18000-3 mode 3, and MIFARE, plus card-emulation (PICC, ISO14443-4A) capability, and up to 21 general-purpose I/Os with PWM functions on GPIO2 and GPIO3.
The security toolbox provides secure key storage and cryptographic acceleration, allowing the PN7642 to replace an external secure element in access-control and authentication designs. Host connectivity is flexible via I2C, SPI, UART, or USB, and the device ships pre-initialized with firmware by version code (C100 = firmware 01.00, C101 = firmware 02.00 with pinless-download mode enabled by default, C102 = firmware 03.00).
Typical applications include door-access readers, industrial NFC configuration ports, point-of-sale peripherals, and embedded secure-provisioning systems.
Design consideration: the PN7642EV (VFBGA) and PN7462AUHN (QFN) are not footprint-compatible despite functional overlap, so package selection must be fixed before PCB layout.

典型應用
PN7642EV 適用於 6 應用s: Door Access Control Readers, Industrial NFC Configuration Ports, Point-of-Sale Peripherals, Embedded Secure Provisioning Systems, Smart Locks and Battery-Powered Entry Devices, Consumer NFC Accessories and Tag Writers.
Door Access Control Readers
The PN7642EV fits door-access readers because its 13.56 MHz PCD stack covers ISO14443-3/4 A/B, ISO15693, FeliCa, and MIFARE credential types in one silicon, while the security toolbox keeps authentication keys inside the chip. In a typical reader, the PN7642EV drives the antenna directly from a 3.3 V or 5 V rail (2.4-5.5 V supported), reads a contactless credential, authenticates it with on-chip cryptography, and toggles a lock driver via one of up to 21 GPIOs. Because the Cortex-M33 and 180 kB flash host the reader firmware and business logic locally, no external MCU or discrete Secure Element is needed, cutting BOM count and shrinking the reader PCB. GPIO3 must be reserved if ULPCD low-power card detection is used.

Industrial NFC Configuration Ports
Industrial equipment increasingly uses NFC instead of DIP switches or USB service ports for parameter setting and commissioning. The PN7642EV suits this role: its Cortex-M33 with 180 kB flash runs a parameter database and configuration interpreter locally, the 2.4-5.5 V input range accepts standard 3.3 V or 5 V industrial rails directly, and I2C or SPI links the controller to the main PLC processor. Service technicians tap a phone or NFC tag to the panel to write setpoints, while the security toolbox ensures only credentialed devices can modify parameters. With up to 21 GPIOs and PWM on GPIO2/GPIO3, it can also drive status LEDs or a buzzer. ISO15693 support enables long-range reading of rugged industrial tags.

Point-of-Sale Peripherals
POS peripherals such as loyalty readers and PIN-pad adjuncts benefit from the PN7642EV's combination of card emulation (PICC, ISO14443-4A) and reader modes in one chip. USB host connectivity simplifies integration with POS terminals that expose USB ports, while UART and I2C serve legacy serial back-ends. The security subsystem provides a hardware root for key storage required in payment-adjacent flows, and the Cortex-M33 executes the terminal-side protocol with 180 kB of flash for application code. Supply from the terminal's 5 V USB rail (within the 2.4-5.5 V range) removes the need for a dedicated regulator. FeliCa and MIFARE coverage supports region-specific transit and wallet cards across global deployments.
推薦
Embedded Secure Provisioning Systems
Device manufacturers use NFC as an out-of-band provisioning channel to inject certificates and keys during production or field commissioning. The PN7642EV is purpose-built here: its security toolbox provides secure key storage and cryptographic acceleration so secrets received over the air never appear in external memory, and the Cortex-M33 firmware can enforce provisioning policy without a host CPU. The chip bridges to the target SoC via I2C or SPI, and the wide 2.4-5.5 V supply range fits both bench fixtures and battery-powered provisioning probes. Since C101 units ship with pinless-download mode enabled by default, firmware update during provisioning is streamlined. Flash is programmable, supporting per-customer firmware customization.
推薦
Smart Locks and Battery-Powered Entry Devices
Battery-powered smart locks need low standby drain and local decision-making. The PN7642EV integrates the reader, MCU, and security in one die, so quiescent budget is concentrated in a single chip rather than three, and wake-on-field operation lets the Cortex-M33 stay idle until a card is presented. The 2.4 V supply floor allows direct operation from two alkaline cells or a single lithium cell across discharge, avoiding boost converters in the power path. Credential verification runs on-chip with keys held in the security subsystem, so a compromised lock enclosure does not expose shared secrets. GPIOs drive the motor H-bridge enable and tamper switch inputs directly within the 21-GPIO budget.

Consumer NFC Accessories and Tag Writers
Consumer accessories - headphones, speakers, toys, and pairing tags - use NFC one-tap pairing and configuration. The PN7642EV consolidates the reader, the application MCU (Cortex-M33, 180 kB flash), and host I/O (I2C, SPI, UART, USB) in a single 64-VFBGA, which suits compact consumer PCBs where a 64-ball 0.4 mm-pitch BGA conserves board area versus QFN-based three-chip stacks. ISO14443-A and FeliCa coverage addresses both global NFC Forum phones and the Japanese market, while MIFARE support handles accessory authentication tags. Developers can reflash the 180 kB flash with custom pairing logic, and firmware suffix C101 simplifies updates through its pinless-download mode.

設計說明
Firmware suffix selection is a sourcing decision, not just a software one. PN7642EV/C100 initializes firmware 01.00, /C101 firmware 02.00 with pinless-download enabled by default, and /C102 firmware 03.00 (per NXP datasheet). If your field-update infrastructure relies on pinless-download, ordering C100 stock creates rework. Also note PN7642EV (64-VFBGA) and PN7462AUHN (QFN) are NOT footprint-compatible - fixing the package before layout avoids a respin. DigiKey stock differs sharply by suffix, so qualify at least two suffixes.
The 64-ball VFBGA requires controlled-impedance layout for the 13.56 MHz antenna matching network: keep the antenna matching capacitors and series resistors within a few millimeters of the RF balls, place a solid ground plane directly under the matching network, and follow the antenna tuning procedure in the NXP design-in package (available from NXP on request, not in the public datasheet). Decouple the 2.4-5.5 V supply with low-ESR ceramics at each supply ball. BGA rework is costly, so verify paste stencil design and X-ray inspection before mass production.
Plan the power budget around the 2.4-5.5 V input range. From a 5 V USB rail the internal LDOs drop the excess, so thermal dissipation rises with load; from a single lithium cell (3.0-4.2 V) headroom is comfortable. If the ultra-low-power card detection (ULPCD) mode is used for battery designs, remember that GPIO3 is then reserved exclusively for aborting ULPCD and cannot serve as a general-purpose I/O or PWM output - budget GPIOs accordingly in the pin assignment before routing.
