PN532 NFC Controller User Manual - Firmware V1.6
User manual for the NXP PN532 NFC controller (firmware V1.6) detailing operating modes, host interfaces (I2C, SPI, HSU), power management, and RF communication protocols.
Overview
This document describes the V1.6 firmware embedded in the NXP PN532, a highly integrated 13.56 MHz contactless communication module. The PN532 is based on an 80C51 microcontroller core with 40 KB ROM and 1 KB RAM, supporting host controller interfaces via I2C, SPI, and High Speed UART (HSU). It supports various operating modes including Proximity Coupling Device (PCD) for FeliCa, ISO/IEC 14443 Type A and B, Mifare, and Innovision Jewel cards, as well as NFCIP-1 and card interface modes. The manual details the device's configuration via GPIOs for standard, PN512 emulation, and RF field testing modes. Additionally, it covers power management strategies such as CPU frequency scaling and low-battery (LowVbat) features to optimize consumption in mobile environments.
Use Cases
- Mobile base-band CPU integration
- Contactless payment and ticketing systems
- NFC initiator or target implementation
- RFID reader/writer development
- Low-power contactless communication modules
