A7102CHTK2/T0BC2CJ

Overview

The A7102CHTK2/T0BC2CJ is a customer programmable security and authentication integrated circuit from the NXP EdgeLock A71CH family. Designed for extended industrial temperature ranges of -40 to +90 °C, it operates in an HVSON8 package (4x4 mm). This component serves as a secure element for IoT applications, providing hardware-based protection for cryptographic keys and credentials. It supports ECC-based authentication, TLS setup, and protected storage functions, enabling zero-touch connection capabilities for devices requiring high-level security.

Feature Summary

• Extended operating temperature range: -40 °C to +90 °C
• HVSON8 (4x4 mm) surface-mount package
• Provisioned and programmable for IBM Watson IoT integration
• Hardware-protected credential access and key derivation

Applications

• Secure IoT device onboarding
• Industrial automation systems
• Smart metering infrastructure
• Remote monitoring endpoints

Procurement Notes

Verify the specific ordering suffix T0BC2CJ confirms the extended temperature grade (-40 to +90 °C) and HVSON8 packaging. Confirm that the 'Provisioned & Programmable' status aligns with the required IBM Watson IoT configuration needs before procurement. Check current availability as distribution status may vary.

Selection Notes

Select this part over the standard temperature variant (A7101CH...) when deployment environments exceed -25 °C or require operation up to +90 °C. Choose the HVSON8 package if board space constraints favor the 4x4 mm footprint over the WLCSP option. Ensure the host MCU supports the necessary SPI interface for communication with the security IC.

Part Context

This component belongs to the EdgeLock A71CH series, which focuses on secure boot and authenticated connections for IoT ecosystems. It complements NXP microcontrollers like the Kinetis and i.MX RT families by offloading complex cryptographic operations and secure storage, ensuring a trusted root of identity for connected devices.

Replacement Considerations

The A7101CHTK2/T0BC2BJ is the standard temperature equivalent within the same package and provisioning profile. For different packaging requirements, the WLCSP variants (e.g., A7102CHUK/T0BC2VAZ) offer the same functionality in a smaller footprint.
