Product Details
ATECC608C-TNGTLSS-G - Trust&GO TLS SOIC Secure Element
ATECC608C-TNGTLSS-G from Microchip Technology is a pre-provisioned Trust&GO TLS secure authentication IC in an 8-lead SOIC package. The -G suffix identifies the manufacturer's production tape-and-reel ordering option.
Technical basis: Microchip ATECC608C-TNGTLS CryptoAuthentication data sheet DS40002516B and the manufacturer's product page. No current price or inventory claim is included.
Overview
ATECC608C-TNGTLS is a pre-provisioned ATECC608C Trust&GO variant for common IoT TLS identity applications. Its fixed security policy, protected keys and certificate storage reduce the need for customer-side secret injection. The exact ATECC608C-TNGTLSS-G code identifies the provisioned SOIC, I2C production order option. Host firmware still requires a correct I2C driver, TLS stack and certificate-chain validation.
Key Advantages
A manufacturing-fixed P-256 identity key is used without exposing it to host memory.
The Trust&GO configuration supports a defined device-identity workflow.
Asymmetric, hash and symmetric functions support embedded authentication.
The manufacturer lists this code as an 8-lead SOIC tape-and-reel presentation.
Feature Summary
Hardware ECDSA signing, verification and ECDH key agreement.
SHA-256, HMAC and AES-128 functions support authenticated protocols.
Compressed X.509 certificate data and fixed slot access policies support identity operations.
Documented features can participate in signed-firmware validation with host enforcement.
Package & Footprint
The registered package is 8-SOIC (0.154", 3.90mm Width), matching Microchip's narrow-body 8-lead SOIC option. The local JPG is a generic package illustration, not a controlled footprint or actual marking image.
- Confirm the latest manufacturer land pattern and pin-1 index.
- Place VCC decoupling near the IC.
- Select I2C pull-ups for the bus level and timing.
Pin Functions
The manufacturer's 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 are the I2C data and clock signals for this exact code.

See the complete data-sheet electrical tables and fixed slot policies for conditional limits.
Replacement Considerations
The -C and -B SOIC codes have different order presentations; U-suffix devices use a UDFN footprint. A different Trust Platform variant is not automatically credential-compatible. Compare package, fixed slot policy, certificate chain and host behavior. No unverified internal alternative link is included.
Manufacturer Information
Microchip data sheet DS40002516B explicitly lists ATECC608C-TNGTLSS-G as a provisioned Trust&GO TLS 8-SOIC I2C production ordering code. It documents the pinout, key-slot policies, command use and package drawings. The Microchip product page describes the family as a pre-provisioned authentication IC for TLS systems.
Applications
Protect authentication keys in connected products.
Integrate device certificates with a host TLS stack.
Use secure-boot resources with host-enforced validation.
Apply documented challenge-response operations.
Quality & Authenticity
Verify the full -TNGTLSS-G code, marking, lot traceability and actual certificate chain. The generic SOIC image does not establish authenticity or provisioning state. Test cryptographic responses in the target system.
FAQ
What does -G identify?
It identifies Microchip's production tape-and-reel SOIC presentation.
Is this exact code I2C?
Yes, Microchip lists it as an I2C device.
Does the generic image prove identity?
No. Verify the physical marking and actual provisioned identity.
Can another variant replace it directly?
Only after checking package, configuration, credentials and host integration.
Engineering Notice
Review current Microchip documentation and errata. Validate supply, I2C timing, host library, certificate trust chain and the full system threat model. Hardware key protection is one component of a secure deployment.
