ECC608-TMNGTLSU

Specialized ICS Overview

The Microchip Technology ECC608-TMNGTLSU is a Trust Manager pre-provisioned secure authenticator from the CryptoAuthentication™ family. It integrates with Kudelski IoT keySTREAM SaaS for remote lifecycle management of cryptographic keys and certificates. The device features an I2C interface, JIL High security rating, and NIST SP 800-90A/B/C certified TRNG. It supports TLS 1.2/1.3 connections, Secure Boot, and dynamic certificate rotation. Operating on 2.0V to 5.5V supply voltage, it includes predefined slot access policies for P-256 identity and attestation keys, with in-field provisioning capabilities for custom PKI.

Specialized ICS Feature Summary

• Pre-provisioned for Kudelski keySTREAM SaaS integration with fixed configuration zone
• JIL High Rating validated against attack potential standards
• NIST CMVP ESV Certified True Random Number Generator (TRNG)
• Supports TLS 1.2/1.3, Secure Boot, and dynamic certificate management

Specialized ICS Applications

• Secure IoT TLS 1.2 and 1.3 connections with custom Root CA setup
• Dynamic certificate management including rotation, revocation, and renewal
• Secure Boot implementation for embedded systems
• End-to-end data protection and private key rotation

Specialized ICS Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the TMNGTLS series is available in both 8-Pad UDFN and 8-Lead SOIC packages. Confirm compatibility with the Kudelski keySTREAM SaaS service, as this variant relies on external cloud infrastructure for in-field provisioning and key management rather than static factory-only configurations.

Specialized ICS Selection Notes

Select this component when hardware security requires remote, dynamic management of cryptographic credentials without physical intervention. It is suitable for devices needing zero-touch deployment where the manufacturer does not handle final PKI customization. Ensure the host MCU supports I2C communication and can accommodate the keySTREAM Trusted Agent library for efficient memory usage.

Specialized ICS Part Context

This part is a specialized variant of the ATECC608/AECC608 family designed specifically for the Trust Manager ecosystem. Unlike standard variants that allow customer-defined configuration, the TMNGTLS units have a locked Configuration Zone and are pre-configured for seamless integration with Kudelski IoT services. It serves as the hardware root of trust for managed IoT deployments.

Specialized ICS Replacement Considerations

Standard ATECC608 or ATECC608B devices require manual provisioning and do not natively support the keySTREAM SaaS workflow out-of-the-box. Direct replacement is possible only if the application architecture is modified to remove reliance on the automated in-field provisioning and remote management features provided by the TMNGTLS variant.
