Product Details
ATECC608C-TNGTLSS-C - Trust&GO TLS Secure Element
ATECC608C-TNGTLSS-C from Microchip Technology is a pre-provisioned Trust&GO TLS secure element with an 8-lead SOIC footprint and I2C host interface. Microchip's ordering table identifies the -C code as the small-reel SOIC presentation.
Technical basis: Microchip ATECC608C-TNGTLS CryptoAuthentication data sheet DS40002516B and the manufacturer's product page. No current price or inventory claim is included.
Overview
The ATECC608C-TNGTLS is a pre-provisioned variant of the ATECC608C, with a fixed configuration for common IoT identity applications. Protected private-key operations, compressed certificate storage and a hardware random-number generator support device authentication and TLS integration. This exact -TNGTLSS-C code selects the SOIC, I2C small-reel order option; it is not a different security configuration from the family identified by the base code.
Key Advantages
A primary P-256 private key is fixed at manufacturing and used without exposing it to host memory.
The Trust&GO policy reduces initial configuration work for supported use cases.
Hardware asymmetric and symmetric functions assist embedded authentication.
The 8-lead package supports designs using the documented narrow-body SOIC footprint.
Feature Summary
Hardware ECDSA signing and verification plus ECDH key agreement.
SHA-256, HMAC and AES-128 operations support authenticated protocols.
Compressed X.509 certificate data and defined slot policies support device identity.
Documented commands and slots can participate in signed-firmware validation.
Package & Footprint
The registered package is 8-SOIC (0.154", 3.90mm Width), corresponding to Microchip's 8-lead narrow-body SOIC option. The image is a generic local package illustration, not a device marking or controlled mechanical drawing.
- Check the latest manufacturer footprint and pin-1 index.
- Place supply bypassing close to the IC.
- Set I2C pull-ups for the selected bus voltage and timing.
Pin Functions
The data-sheet SOIC top view assigns pins 1, 2, 3 and 7 to NC, pin 4 to GND, pin 5 to SDA, pin 6 to SCL and pin 8 to VCC. SDA and SCL form the I2C connection for this exact order code.

Replacement Considerations
Other ATECC608C-TNGTLS SOIC presentations may differ in ordering format, while U-suffix parts use a UDFN footprint. A different secure-element family or configuration is not automatically interchangeable. Compare the provisioned credentials, slot access policies, I2C behavior, package and certificate lifecycle. No unverified internal alternative link is included.
Manufacturer Information
Microchip data sheet DS40002516B explicitly lists ATECC608C-TNGTLSS-C as a provisioned Trust&GO TLS, 8-SOIC, I2C small-reel ordering code. It documents key-slot policy, pinout, commands and package drawings. The manufacturer product page identifies the family as a pre-provisioned secure authentication IC for TLS systems.
Applications
Protect private-key operations for connected products.
Integrate device certificates with a host TLS stack.
Evaluate secure-boot resources as part of host-enforced validation.
Apply documented challenge-response operations in approved designs.
Quality & Authenticity
Verify the full -TNGTLSS-C order code, marking, lot traceability and actual device certificate chain. The generic SOIC image does not establish identity or provisioned state. Validate cryptographic responses in the target system.
FAQ
What does the -C suffix select?
Microchip identifies this as the SOIC small-reel ordering presentation.
Is the host interface I2C?
Yes, the exact order code is listed as an I2C device.
Does the package image show the actual marking?
No. It is a generic SOIC illustration; confirm markings using the physical device and manufacturer documentation.
Can a different secure element be substituted directly?
Not without reviewing credentials, configuration, commands and footprint.
Engineering Notice
Review the latest Microchip documentation, errata and lifecycle notices. Verify supply, I2C timing, certificate validation, host-library behavior and system threat model before design release. A secure element is one part of a complete security architecture.
