Product Details
ATECC608C-TFLXTLSS - TrustFLEX TLS SOIC Secure Element
ATECC608C-TFLXTLSS from Microchip Technology is a preconfigured TrustFLEX TLS secure element in an 8-lead SOIC package. Its protected cryptographic operations and configurable credential provisioning support embedded device identity.
Technical basis: Microchip ATECC608C-TFLXTLS CryptoAuthentication data sheet DS40002515 and the manufacturer's product page. No current price or inventory claim is included.
Overview
ATECC608C-TFLXTLS is the TrustFLEX variant of Microchip's ATECC608C secure authentication IC. The configuration is defined for common TLS identity use cases, while selected credentials can be customized through the Trust Platform Design Suite and approved provisioning process. The exact -TFLXTLSS code denotes the provisioned 8-SOIC production ordering option. Unlike Trust&GO, the intended customer certificate chain and permitted policy choices require confirmation for each deployment.
Key Advantages
Sensitive private-key operations remain inside secure hardware.
Customer identity material can be introduced through the supported provisioning workflow.
ECC, hashing and symmetric functions support embedded TLS authentication designs.
The S suffix selects a documented narrow-body 8-lead SOIC option.
Feature Summary
Hardware ECDSA sign/verify and ECDH key agreement.
SHA-256, HMAC and AES-128 capabilities support authenticated protocols.
Protected key slots and compressed certificate storage support device identity.
Signed-firmware workflows can use documented verification features with host enforcement.
Package & Footprint
The registered package is 8-SOIC (0.154", 3.90mm Width). The local JPG is a generic package illustration, not a controlled mechanical drawing or actual device marking. Confirm dimensions, land pattern and pin-1 orientation in current Microchip documentation.
- Use the latest SOIC footprint and pin-1 reference.
- Place supply decoupling close to the device.
- Route the configured I2C or single-wire host interface correctly.
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. In I2C mode, SDA is data and SCL is clock; the single-wire option changes host use of these signals. Confirm the provisioned interface before board release.

Replacement Considerations
Prototype and UDFN order options differ in presentation or footprint. TrustFLEX, Trust&GO and TrustCUSTOM policies are not interchangeable merely because they share the ATECC608C family. Compare provisioned credentials, interface, package, commands and lifecycle before substitution. No unverified internal alternative link is included.
Manufacturer Information
Microchip data sheet DS40002515 lists ATECC608C-TFLXTLSS as a provisioned TrustFLEX TLS 8-SOIC option and explains that I2C or single-wire mode is selected through the Trust Platform configuration workflow. It documents slot policies, electrical conditions, pinout and package drawings. The product page describes customer-credential customization within the TrustFLEX platform.
Applications
Protect client-authentication keys and certificate operations.
Provision application-specific credentials through the supported workflow.
Support signed-image validation when the selected policy enables it.
Use protected challenge-response operations in approved designs.
Quality & Authenticity
Verify the full -TFLXTLSS code, marking, lot traceability and actual provisioned certificate/key policy. A generic SOIC image does not prove identity or configuration. Validate cryptographic responses and certificate chain in the target system.
FAQ
What package does S identify?
It identifies Microchip's 8-lead SOIC option.
Is the host interface always I2C?
No. TrustFLEX supports I2C or single-wire according to the selected configuration.
Are credentials identical across all units?
Verify the customer provisioning record and certificate chain; do not assume identical application credentials.
Can Trust&GO replace it without changes?
No. Compare security policy, certificate handling and host integration first.
Engineering Notice
Review current Microchip data, errata and provisioning records. Validate supply, interface timing, host library, certificate trust chain and threat model. Hardware key protection alone does not secure an entire TLS deployment.
