A7101CHUK/T0BC2HAZ

Overview

The A7101CHUK/T0BC2HAZ is a customer-programmable security and authentication integrated circuit from the NXP A71CH family. It operates within a standard temperature range of -25°C to +85°C and is housed in a WLCSP package with reel packaging. The device functions as a secure element, providing hardware-based protection for cryptographic keys and credentials. It supports various authentication protocols including TLS-PKI, TLS-PSK, and HMAC for connectionless message integrity. The component is designed for integration with host processors via dedicated interfaces to manage secure boot, protected storage, and key derivation.

Feature Summary

• Customer-programmable security IC supporting standard temperature range (-25 to +85 °C)
• WLCSP package configuration with reel shipping format
• Hardware support for ECC-based authentication, TLS-PKI, TLS-PSK, and HMAC
• Protected credential access with key wrapping, derivation, and locking mechanisms

Applications

• Secure IoT device onboarding and zero-touch provisioning
• Authentication microcontrollers for edge devices requiring root-of-trust
• Secure storage solutions for host processor cryptographic keys

Procurement Notes

Verify the specific ordering suffix T0BC2HAZ to confirm the WLCSP package type and reel packaging configuration. Ensure compatibility with the required standard temperature range (-25 to +85 °C) for the target application environment. Cross-reference the 12NC 9353 694 82023 for accurate supply chain tracking and availability checks against current distributor inventories.

Selection Notes

Select this variant over the HVSON8 version (A7101CHTK2) when board space constraints necessitate the smaller WLCSP footprint. Choose the standard temperature grade (-25 to +85 °C) if extended industrial ranges are not required. Confirm that the host system can support the necessary encryption and verification interfaces provided by the A71CH series for seamless integration.

Part Context

This component belongs to the A71CH series of security ICs, which includes variants like the A7101CGTK2. The series offers both customer-programmable and provisioned options, such as those ready for IBM Watson IoT. The A7101CHUK/T0BC2HAZ specifically utilizes the WLCSP package, distinguishing it from the HVSON8 packages found in other family members like the A7101CHTK2/T0BC2VJ.

Replacement Considerations

Direct replacements within the same package and temperature grade include the A7101CHTK2/T0BC2VJ, though it uses an HVSON8 package instead of WLCSP. For extended temperature requirements, the A7102CHUK/T0BC2VAZ serves as the functional equivalent with a -40 to +90 °C rating.
