Product Details
SE051H2HQ1/Z0112Z - EdgeLock Secure Element
NXP SE051H2HQ1/Z0112Z is an EdgeLock SE051H2 secure element intended for Matter-connected devices and NFC-assisted commissioning. NXP's ordering table identifies this exact orderable part number and its HQ1 HX2QFN20 package.
Verify the exact configuration, credentials and host integration against NXP documentation before design release.
Overview
The SE051H2 combines a tamper-resistant secure-element platform, an I2C host interface and an ISO 14443-A contactless interface. NXP describes the H variant as pre-configured for Matter security and NFC commissioning. The device works alongside a host MCU or MPU rather than replacing it.
Key Advantages
The H configuration is designed for smart-home Matter security workflows.
The contactless interface and Type 4 Tag functionality can support reading onboarding information.
Secure objects and access policies support key and data protection.
I2C communication and NXP Plug & Trust middleware connect the device to a host controller.
Feature Summary
I2C target interface for the host and ISO 14443-A contactless capability.
NXP documents keys, binary files, counters and other protected object types.
Cryptographic functions, random-number generation and secure messaging are provided according to the installed configuration.
The H2 ordering designation represents the -40°C to +105°C ambient grade.
Package & Footprint
NXP's SE051 data sheet maps HQ1 to the 20-terminal HX2QFN20 package and lists the exact SE051H2HQ1/Z0112Z orderable code. NXP package information identifies SOT1969 for this family. The package is not yet registered in the local package workbook, and no matching local JPG has been verified.
- Use the NXP SOT1969/HX2QFN20 mechanical drawing to establish the land pattern.
- Check terminal-1 indication, exposed-pad guidance and antenna routing in the applicable NXP design documents.
- Do not infer a footprint from another QFN20 variant.
Package image unavailable locally; no unverified image is displayed.
Pin Functions
The NXP HX2QFN20 pin diagram identifies VCC, VIN and VSS supplies, I2C_SDA and I2C_SCL for host communication, LA and LB for the contactless antenna, plus control and general-purpose interfaces. The exact terminal numbers and electrical connections must be taken from the manufacturer's pin table and schematic guidance.
ISO 7816 functions depend on configuration; do not assume they are enabled for this orderable variant.
Key Specifications
| Function | IoT secure element, SE051H2 configuration |
|---|---|
| Orderable part number | SE051H2HQ1/Z0112Z |
| Package | HX2QFN20 (HQ1; SOT1969 family) |
| Characterized supply | 1.62 V to 3.6 V |
| Ambient temperature | -40°C to +105°C for grade 2 |
| Host interface | I2C target, default address 0x48 |
| I2C target clock | Up to 3.4 MHz with clock stretching enabled; default configuration limits operation to 1 MHz |
| Contactless interface | ISO 14443-A |
| Physical package terminals | 20 |
The 6 V figure in NXP limiting notes is not the characterized operating supply; design to the recommended operating range.
Replacement Considerations
Other SE051 variants may share the physical package but differ in pre-provisioning, applets, security credentials or enabled interfaces. Confirm complete order code, configuration identifier, Matter/NFC functions, lifecycle state, host software and pin compatibility before substitution. No other part is represented as a verified drop-in replacement.
Manufacturer Information
NXP Semiconductors lists the exact SE051H2HQ1/Z0112Z code in its SE051 product data sheet, revision 2.0 dated 8 July 2024. The SE051 configuration note AN12973 describes the H option for Matter and NFC commissioning. Consult the latest manufacturer revisions for final design decisions.
Applications
Protected device identity and onboarding workflows.
Contactless access to commissioning information where supported by system design.
Secure connection and credential storage for host-controlled IoT equipment.
Security architectures that use a discrete secure element as a root of trust.
Quality & Authenticity
Verify the exact manufacturer part marking, package form, orientation and device configuration. Provision and validate credentials using the approved NXP and system-owner process; physical package similarity alone does not establish functional equivalence.
FAQ
What does the H2 variant identify?
NXP's ordering guide identifies H as a configuration option and grade 2 as the -40°C to +105°C operating-ambient range.
Which package is specified?
HQ1 denotes HX2QFN20. The local catalog package field and registry still require reconciliation.
Does it work without a host?
The SE051 is designed as an auxiliary security device attached to a host controller, typically over I2C.
Is a package image verified?
No matching local JPG was found; the mechanical drawing must be checked directly in NXP documentation.
Engineering Notice
Confirm current NXP configuration, electrical limits, security lifecycle, Matter certification requirements, antenna design and host integration. This page does not replace the product data sheet or qualification testing. Local package registration and image verification remain open.
