ATECC608B-TNGLORAS-G

Specialized ICS Overview

The ATECC608B-TNGLORAS-G is a CryptoAuthentication™ hardware security component manufactured by Microchip Technology. It provides secure key storage and cryptographic operations within an isolated environment, protecting sensitive data from physical and software attacks. The device supports ECC P-256, SHA-256, AES-128, and HMAC algorithms. It features a 16KB EEPROM for configuration and user data, along with a unique 72-bit serial number. This specific variant is supplied in an 8-SOIC package via Tape & Reel (TR) packaging, designed for surface-mount assembly in embedded systems requiring robust authentication.

Specialized ICS Procurement Notes

Verify the ordering suffix TNGLORAS-G against official Microchip documentation to confirm specific tape-and-reel specifications and regional compliance markings. Ensure the 8-SOIC package dimensions align with PCB footprint requirements. Confirm that the TR packaging format matches automated pick-and-place equipment capabilities for the production line.

Specialized ICS Selection Notes

Select this model when a surface-mount 8-SOIC form factor is required for space-constrained designs. The TR packaging is optimal for high-volume automated manufacturing. Compare against other ATECC608 variants if different pinouts or temperature ranges are needed, ensuring the selected part meets the specific interface and memory requirements of the target application.

Specialized ICS Part Context

This component belongs to the Microchip CryptoAuthentication™ family, which specializes in low-cost, high-security authentication solutions. The ATECC608B series is widely used in IoT ecosystems to replace software-based security implementations, providing hardware-rooted trust for devices connecting to cloud platforms like AWS IoT Core or Azure IoT Hub.

Specialized ICS Replacement Considerations

Direct replacements include other ATECC608B variants with compatible packages such as ATECC608B-MAH5O-T (UDFN-8) or ATECC608B-SSHDA-T (SOIC). Verify pin compatibility and EEPROM size before substitution. Cross-model migration may require firmware adjustments due to differences in command sets or physical interfaces.
