ECC608-TMNGTLSS

Specialized ICS Overview

The Microchip Technology ECC608-TMNGTLS is a Trust Manager pre-provisioned secure authenticator based on the ATECC608 architecture. It integrates with Kudelski IoT keySTREAM SaaS for remote lifecycle management of cryptographic credentials. The device features an I2C interface, operates within a supply voltage range of 2.0V to 5.5V and I/O levels of 1.8V to 5.5V, and supports industrial temperatures from -40°C to +85°C. It includes a NIST SP 800-90A/B/C certified True Random Number Generator (TRNG) and JIL High Rating validation. The chip provides 1,400 bytes of EEPROM memory divided into Configuration, Data, and OTP zones, with predefined slot access policies optimized for in-field provisioning of PKI certificates and keys.

Specialized ICS Feature Summary

• Pre-provisioned for Kudelski IoT keySTREAM SaaS integration, enabling zero-touch in-field PKI and TLS credential management.
• JIL High Rating validated against attack potential standards with internal high-quality TRNG certified by NIST CMVP.
• Fixed configuration zone containing unique serial numbers and locked access policies; default I2C address is 0x38.
• Supports Secure Boot via Slot 15 public key and Slot 13 digest, alongside AES128 operations and I/O protection keys.

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 for security agility.

Specialized ICS Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the ECC608-TMNGTLS family includes both 8-Pad UDFN and 8-Lead SOIC variants. Confirm compatibility with the Kudelski IoT keySTREAM SaaS service, as this device relies on external cloud infrastructure for full functionality. Check datasheet specifications for I2C address settings, noting the default differs from standard ECC608 devices.

Specialized ICS Selection Notes

Select the ECC608-TMNGTLS when dynamic, cloud-managed identity and certificate lifecycle are required without manufacturing-time provisioning. Ensure the host MCU supports I2C communication at compatible voltage levels (1.8V to 5.5V). Consider the fixed configuration constraints; this variant does not allow customer modification of the Configuration Zone or Slot Access Policies after shipment.

Specialized ICS Part Context

This component belongs to the CryptoAuthentication™ series, specifically designed as a Trust Manager solution. It serves as a hardware root of trust for IoT devices, bridging physical security with software-defined identity management through the keySTREAM platform. It complements microcontrollers by offloading complex cryptographic operations and secure storage.

Specialized ICS Replacement Considerations

Standard ATECC608 variants lack the pre-provisioning for keySTREAM SaaS and have different default I2C addresses. Direct functional replacement requires verifying SaaS compatibility and updating firmware to handle the distinct I2C addressing and locked configuration zones.

Specialized ICS FAQ

Can the Configuration Zone be modified after purchase?

No, the Configuration Zone is permanently locked upon shipment. The slot access policies and device configuration are fixed and cannot be updated by the customer.

What is the default I2C address for this device?

The default 7-bit I2C address is 0x38. This differs from the standard ECC608 device, so host firmware must be configured accordingly.

How are cryptographic keys managed in this device?

Keys are provisioned in-field via the Kudelski IoT keySTREAM SaaS. The device comes pre-provisioned with initial keys to connect to the service, which then manages ownership, certificates, and key rotation remotely.
