SE050A1HQ1/Z01SGZ

Specialized ICS Overview

The NXP SE050A1HQ1/Z01SGZ is an IoT secure element providing a root of trust at the IC level. It features Common Criteria EAL 6+ certification and supports RSA up to 4096-bit, ECC (NIST, Brainpool, Ed25519), AES, and SHA algorithms. The device includes 50 kB of user flash memory and operates on a supply voltage of 1.62 V to 3.6 V. Communication occurs via I²C target mode (up to 3.4 MHz) and I²C controller mode (up to 400 kHz). It utilizes a JavaCard OS with a pre-installed IoT applet and offers ISO14443-A contactless interface support.

Specialized ICS Feature Summary

• Integrated 50 kB secure user flash memory with dynamic file system
• Dual I²C interfaces: Target mode (HS up to 3.4 MHz) and Controller mode (Fast up to 400 kHz)

Specialized ICS Applications

• Smart Industry
• Secure connection to public/private clouds
• Device-to-device authentication

Specialized ICS Procurement Notes

Verify the specific configuration suffix Z01SGZ against the official SE050 ordering table to confirm key provisioning options and pre-injected credentials. Ensure the selected variant matches the required temperature range (-25 °C to 85 °C for '1' suffix) and package type (HX2QFN20). Confirm compatibility with host MCU I²C clock stretching capabilities if operating above 600 kHz.

Specialized ICS Selection Notes

Select this variant for applications requiring standard industrial temperature range (-25 °C to 85 °C) and specific credential injection profiles associated with the 'A1' configuration. Compare against SE050E or SE050F variants if extended crypto features like GCM/CCM or FIPS 140-2 Level 3 certification are required. Ensure the host system supports the T=1 over I²C protocol for command encapsulation.

Specialized ICS Part Context

This component belongs to the EdgeLock SE050 Plug & Trust family. It is pin-compatible with other SE050 variants such as SE050A2, SE050B1, and SE050C1. The 'A1' designation indicates a specific applet configuration with defined key provisioning options, distinct from the newer SE050E platform which adds AES-GCM/CCM support.

Specialized ICS FAQ

What is the default I²C target address?

The default target address is configured to 0x48.

Does this part support ISO7816 interface?

ISO7816 is not enabled in generic SE050 configurations but may be available on customer request.

What is the maximum I²C target clock frequency?

It supports High-Speed mode up to 3.4 MHz when clock stretching is enabled; otherwise, it is limited to 1 MHz.
