Product Details
ATECC608C-TNGTLSS-B - Trust&GO TLS SOIC Prototype Secure Element
ATECC608C-TNGTLSS-B from Microchip Technology is a pre-provisioned Trust&GO TLS secure element supplied as the 8-SOIC prototype bulk ordering option. It provides hardware-backed identity and cryptographic operations for embedded authentication.
Technical basis: Microchip ATECC608C-TNGTLS CryptoAuthentication data sheet DS40002516B and the manufacturer's product page. No current price or inventory claim is made.
Overview
ATECC608C-TNGTLS is a pre-provisioned ATECC608C Trust&GO variant with defined key-slot policies and credentials for common IoT TLS identity use cases. The exact -TNGTLSS-B code denotes the SOIC prototype bulk presentation, not a different cryptographic configuration. Host firmware must implement the appropriate I2C driver, TLS integration and certificate-chain validation.
Key Advantages
A manufacturing-fixed P-256 identity key is used without exposing it to host application memory.
Defined Trust&GO configuration supports repeatable evaluation.
The -B code identifies Microchip's SOIC prototype bulk option.
Sleep operation supports power-sensitive connected products.
Feature Summary
Hardware ECDSA signing, verification and ECDH key agreement.
SHA-256, HMAC and AES-128 support authenticated workflows.
Compressed X.509 certificate data and defined access policies support identity operations.
A hardware random-number generator and secure-boot resources aid integrated system designs.
Package & Footprint
The registered package is 8-SOIC (0.154", 3.90mm Width). The local JPG is a generic package illustration; use Microchip's latest controlled drawing for dimensions, land pattern and pin-1 index.
- Verify the current SOIC footprint and pin orientation.
- Place VCC bypassing close to the device.
- Choose I2C pull-ups for bus voltage and timing.
Pin Functions
The manufacturer's SOIC top view shows pins 1, 2, 3 and 7 as NC; pin 4 as GND; pin 5 as SDA; pin 6 as SCL; and pin 8 as VCC. This exact order code uses the I2C interface.

Refer to the complete data sheet for conditional limits and provisioned slot policy.
Replacement Considerations
Other SOIC order presentations and UDFN variants differ in supply format or footprint. Compare exact credentials, fixed slot permissions, I2C configuration, package and trust-service requirements before substitution. No unverified internal alternative link is included.
Manufacturer Information
Microchip data sheet DS40002516B explicitly identifies ATECC608C-TNGTLSS-B as the Trust&GO TLS 8-SOIC I2C prototype bulk option. It documents pinout, security policy, commands and package details. The manufacturer's product page describes the pre-provisioned TLS secure-element family.
Applications
Prototype device authentication with protected keys.
Integrate the device certificate with a host TLS stack.
Evaluate secure-boot resources with host enforcement.
Test documented challenge-response functions.
Quality & Authenticity
Verify the full -TNGTLSS-B code, marking, lot traceability and actual certificate chain. A generic SOIC illustration cannot establish device identity or provisioning state.
FAQ
What does -B indicate?
It denotes Microchip's prototype bulk presentation for the SOIC variant.
Is the host connection I2C?
Yes, this exact ordering code is listed as an I2C device.
Is the image a device-specific marking?
No. It is a generic SOIC package illustration.
Can another security IC replace it directly?
Not without checking credentials, slot policy, interface and footprint.
Engineering Notice
Consult the latest Microchip documentation and errata. Validate electrical limits, bus timing, certificate trust chain, host library and the full application threat model before design release.
