PN7642
NXP
The PN7642 consists of two main memory areas, one for the NXP secure firmware and another for the user application.
Application NoteNxp
Firmware update on PN7642
Instructions for updating secure firmware and user applications on the PN7642 NFC controller via IAP, host interface, or NXP NFC Cockpit.
Overview
This application note provides a detailed guide on performing firmware updates for the NXP PN7642 NFC controller. It explains the dual memory architecture, which consists of dedicated areas for NXP secure firmware and user applications. The document outlines three primary update methods: In-Application Programming (IAP) using MCUXpresso SDK examples, Host Interface (HIF) updates via an external MCU such as the LPC55S16 using the ROM bootloader, and USB-based updates through the NXP NFC Cockpit tool. Additionally, it covers firmware versioning rules, including major and minor version compatibility, and provides hardware setup instructions for evaluation boards like the OM27642.
Use Cases
- Updating secure NXP firmware on PN7642 devices
- Flashing user applications via IAP during development
- Implementing host-based firmware download routines via SPI, I2C, or UART
- Using NXP NFC Cockpit for device configuration and firmware management
- Upgrading NFC controller firmware while maintaining RF and protocol settings
