SE050B1HQ1/Z01SEZ

Specialized ICS Overview

The SE050B1HQ1/Z01SEZ is an IoT secure element from NXP Semiconductors, designed to provide a root of trust at the IC level. It operates within a supply voltage range of 1.62 V to 3.6 V and supports an operating ambient temperature of -25 °C to +85 °C. The device features Common Criteria EAL 6+ certification and FIPS 140-2 Level 3 compliance. It includes up to 50 kB of secured user flash memory for credential storage. Communication interfaces include an I²C target supporting High-Speed mode (up to 3.4 MHz) and an I²C controller in Fast Mode (400 kbit/s). The component is housed in a 20-HX2QFN package with dimensions of 3x3 mm.

Specialized ICS Procurement Notes

Verify the specific configuration suffix Z01SEZ against the official SE050 ordering table to confirm key provisioning options and pre-installed applet settings. Ensure the selected variant matches the required temperature range (-25 °C to +85 °C) and interface capabilities for the target design.

Specialized ICS Selection Notes

Select this variant based on the required cryptographic feature set and key injection method defined by the 'B' applet configuration. Confirm compatibility with the host MCU's I²C clock stretching support if operating above 600 kHz. Verify that the 20-HX2QFN package footprint aligns with the PCB layout guidelines provided in the datasheet.

Specialized ICS Part Context

This part belongs to the EdgeLock SE050 Plug & Trust Secure Element family. It is one of several pin-to-pin compatible variants differentiated by application-specific configurations and key provisioning methods. The SE050 platform serves as a turnkey solution for IoT security, integrating with various host operating systems via middleware.

Specialized ICS Replacement Considerations

Other SE050 variants such as SE050A1HQ1/Z01SGZ or SE050C1HQ1/Z01SCZ are pin-compatible but may differ in pre-provisioned keys or supported cryptographic curves. Verify functional equivalence before substitution.
