NXP AN12695: MIFARE SAM AV3 Quick Start-Up Guide

A guide for the MIFARE SAM AV3 secure application module, detailing cryptographic features, package options, ISO/IEC 7816 and I2C interfaces, and hardware design considerations.

View application note

Overview

This application note provides a start-up guide for the NXP MIFARE SAM AV3 Secure Application Module (SAM). It describes the device's primary function in providing secure cryptographic key storage and functions (DES, TDEA, AES, RSA, ECC, and SHA) for terminals to access MIFARE products. The document covers available delivery formats including HVQFN32, PCM1.5 contact modules, and sawn wafers. It details communication interfaces such as ISO/IEC 7816-3 (up to 1.5 Mbps) and the I2C slave interface. Additionally, it provides hardware design considerations for I2C voltage levels, interface selection via TP1, and compares the AV3 features against the previous SAM AV2.

Use Cases

  • Secure terminal development for MIFARE products
  • Hardware-based cryptographic key management
  • Secure host-to-terminal communication
  • Access control system security
  • Point of Service (POS) terminal design
