A7102CGHN1/T0B0AEL

Overview

The A7102CGHN1 is a secure element from NXP’s EdgeLock® SE050 series, designed for zero-touch IoT connectivity. It operates within an extended temperature range of -40°C to +90°C and utilizes a WLCSP (2x2 mm) package. The device provides IC-level root of trust, protecting injected credentials with protected access mechanisms. It supports host processor interfaces for ECC-based authentication, TLS-PKI/PSK setup, and HMAC message verification. Key storage features include key wrapping, derivation, and locking mechanisms to ensure data integrity.

Feature Summary

• Extended temperature operation (-40°C to +90°C)
• WLCSP 2x2 mm compact package
• ECC-based authentication and TLS support
• Protected credential storage with key locking

Applications

• Secure IoT edge devices
• Industrial building automation
• Smart metering endpoints

Procurement Notes

Verify the specific suffix 'T0B0AEL' against official NXP documentation to confirm tape-and-reel packaging specifications and lot traceability requirements. Ensure compatibility with the target MCU's SPI or I2C interface constraints before procurement.

Selection Notes

Select the A7102 variant over the A7101 when deployment environments require extended industrial temperature ranges up to 90°C. Choose the WLCSP package for applications with strict board space limitations compared to the HVSON8 option.

Part Context

This component belongs to the EdgeLock® SE050 family, which offers plug-and-trust security solutions. It complements NXP microcontrollers like the Kinetis KW41Z and i.MX processors by offloading cryptographic operations and secure key storage from the main application processor.

Replacement Considerations

The A7101CGHN1/T0B0AEL serves as a functional substitute if the extended temperature range requirement is relaxed to commercial limits (-25°C to +85°C). Verify pinout compatibility between the A7101 and A7102 variants prior to substitution.
