ATECC608B Trust Platform Variants and Provisioning Services
Microchip provides a variety of pre-configured variants of the ATECC608B secure elements and a suite of tools to
assist customers in developing applications using secure elements while minimizing the learning curve associated
with cryptographic security.
Microchip offers secure provisioning services for the ATECC608B through the Trust Platform. It leverages the Trust
Platform Design Suite set of tools (TPDS), and offers 3 provisioning flows:
•
•
•
Trust&GO: Pre-configured and pre-provisioned Secure Elements for fix-function Use Cases
TrustFLEX: Pre-configured & provisioned Secure Element with customer-unique credentials
TrustCUSTOM: Fully customizable Secure Element including configuration and provisioning with customerunique credentials
The Trust&GO flow provides pre-configured and pre-provisioned secure elements. These products are defined to
meet common use case applications for customers that do not require unique credentials. These devices are
provided as is and can be ordered directly from Microchip as easily as any standard product.
The TrustFLEX flow leverages the TrustFLEX configurator to input unique customer credentials into a pre-defined
configuration and generate a Secure Exchange Package. This package is, then, deployed via the Microchip Secure
Provisioning System to enable device ordering. Then, only the customer designated in the Secure Exchange
Package can order these devices.
The TrustCUSTOM flow leverages the TrustCUSTOM configurator and provides the ability to fully configure the
ATECC608B device to meet the security requirements for a given application. At the end of the process, a Secure
Exchange Package is generated that is deployed to the Microchip Secure Provisioning System. Then, only the
customer designated in the Secure Exchange Package can order these devices.
Important: The Microchip Secure Provisioning System is based on Hardware Security Modules (HSMs).

Compatibility

Compatibility
4.1
Microchip ATECC608A
The ATECC608B is designed to provide an enhanced security profile over that of the ATECC608A while maintaining
backwards compatibility. The following details the changes and enhancements to the device. No configuration bit
fields have changed. Configurations defined for the ATECC608A will be functionally identical with the ATECC608B
device.
Corrections, Enhancements
The following items have been corrected or enhanced in the ATECC608B device:
• Two temperature ranges are now available:
– Standard Industrial Temperature Range: -40℃ to +85℃
– Standard Industrial Temperature Range: -40℃ to +100℃
• Operating at a low I2C Frequency with multiple devices on the bus will no longer create a bus contention issue.
• Modifications to Command Timings for Verify, SecureBoot, Lock and Read commands.
•
4.2
New Packaging Options: 3-Lead Contact Package and WLCSP for qualified customers. (Contact Microchip
Sales for the WLCSP Option.)
Microchip ATECC508A
The ATECC608B is designed to be fully compatible with the ATECC508A devices with the limited exception of the
functions listed below. If the ATECC608B is properly configured, software written for the ATECC508A will work with
the ATECC608B without any required changes, again with the exception of the functions listed below.
Note: Most elements of the configuration zone in the ATECC608B are identical in both location and value with the
ATECC508A. However, the initial values that had been stored in the LastKeyUse field may need to be changed to
conform to the new definition of those bytes which can be found in this document. That field contained the initial
count for the Slot 15 limited use function which is supported in the ATECC608B via the monotonic counters.
CAUTION
The execution times of commands have changed between the ATECC608B and the ATECC508A. These
changes will not cause an issue if polling has been implemented. If fixed timing has been used, this must
be evaluated and updated as required.
New Features in ATECC608B vs. ATECC508A
• Secure boot function with IO encryption and authentication
• KDF command, supporting PRF, HKDF, AES
•
AES command, including encrypt/decrypt
•
•
•
GFM calculation function for GCM AEAD mode of AES
Updated NIST SP800-90 A/B/C Random Number Generator
Flexible SHA/HMAC command with context save/restore
•
SHA command execution time significantly reduced
•
•
•
•
•
Volatile Key Permitting to prevent device transfer
Transport Key Locking to protect programmed devices during delivery
Counter Limit Match function
Ephemeral key generation in SRAM, also supported with ECDH and KDF
Verify command output can be validated with a MAC

Features Eliminated in ATECC608B vs. ATECC508A
• HMAC command removed, replaced via new more powerful SHA command
•
•
•
•
4.3
OTP consumption mode eliminated, now read only
Pause command eliminated along with related Selector function in UpdateExtra
Slot 15 special limited use eliminated, replaced with standard monotonic counter limited use
SHA command no longer uses TempKey during the digest calculation and the result in TempKey is unchanged
throughout the SHA operation. TempKey can however still be used to initialize the SHA for the HMAC_Start or to
store the final digest.
Microchip ATSHA204A, ATECC108A
The ATECC608B is generally compatible with all ATSHA204/A and ATECC108/A devices. If properly configured,
it can be used in most situations where these devices are currently employed. For ATSHA204A and ATECC108A
compatibility restrictions, see the ATECC508A data sheet.

Package Marking Information
As part of Microchip’s overall security features, the part marking for all crypto devices is intentionally vague. The
marking on the top of the package does not provide any information as to the actual device type or the manufacturer
of the device. The alphanumeric code on the package provides manufacturing information and will vary with
assembly lot. It is recommended that the packaging mark not be used as part of any incoming inspection procedure.
