Product Details

ATECC608A-SSHDA-B - ECC-P256 I2C Secure Element, SOIC Tube

ATECC608A-SSHDA-B from Microchip Technology is an ECC-P256 authentication IC in an 8-lead SOIC supplied in 100-piece tubes.

Specifications were checked against the manufacturer data sheet and current distributor listing.

Overview

ATECC608A isolates private keys for ECDSA, ECDH, SHA-256 and AES-128 operations. SSHDA-B selects the I2C industrial-temperature SOIC tube format.

Design focus: Microchip marks ATECC608A Not Recommended for New Designs. Verify provisioning, security configuration and lifecycle before use.

Replacement Considerations

ATECC608A-SSHDA-T is a related product in the library. Confirm electrical behavior, package, pinout, ordering media and configuration before substitution.

Similarity of family name or package does not establish drop-in compatibility.

Manufacturer Information

Microchip marks the A family Not Recommended for New Designs and recommends B; SSHDA-B is the I2C SOIC tube ordering code.

Applications

Established IoT products

Maintain authenticated network identity in qualified designs.

Accessory security

Protect credentials for replaceable modules.

Quality & Authenticity

Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.

FAQ

What is the main function?

ECC-P256 secure authentication and key agreement

What package is used?

8-SOIC

Can the related part be substituted directly?

No. Validate all electrical, mechanical and configuration differences first.

Is the package image ready?

Yes. The registered package JPG is present locally.

Engineering Notice

Use the latest manufacturer documentation for schematic, PCB, thermal and production approval. Distributor attributes are useful for sourcing but do not replace the official data sheet.
