Product Details
ATECC608C-TCSMS - TrustCUSTOM SOIC Secure Element
ATECC608C-TCSMS from Microchip Technology is the 8-lead SOIC TrustCUSTOM ordering option of the ATECC608C secure authentication IC. TrustCUSTOM is intended for customer-defined security configuration and provisioning, rather than the fixed Trust&GO identity flow.
Technical basis: Microchip ATECC608C Summary Data Sheet DS40002513 and its Trust Platform variant table. No current price or inventory claim is included.
Overview
The ATECC608C combines protected key storage and hardware cryptographic operations for embedded authentication. Microchip identifies ATECC608C-TCSMS as the TrustCUSTOM 8-SOIC option, equivalent in its standard blank form to an ATECC608C-SSHDA device. TrustCUSTOM supports a customer-specific configuration and secure provisioning workflow. Device behavior and credential contents depend on that approved configuration, so generic secure-element claims must not be mistaken for an already provisioned identity.
Key Advantages
TrustCUSTOM permits application-specific configuration and credentials.
Cryptographic keys can be held in secure hardware rather than host memory.
Host and provisioning design can target the product's selected security use case.
The S suffix selects Microchip's narrow-body 8-lead SOIC option.
Feature Summary
Hardware ECDSA and ECDH functions support authentication and key agreement.
SHA-256, HMAC and AES-128 functions support authenticated data workflows.
Keys, certificates and data may be stored under a customer-defined access policy.
Integrated hardware randomness supports key-generation use cases.
Package & Footprint
The registered package is 8-SOIC (0.154", 3.90mm Width). The local image is a generic SOIC illustration, not device-specific marking or a controlled land pattern. Use the current Microchip mechanical drawing for dimensions and orientation.
- Confirm the manufacturer SOIC footprint and pin-1 index.
- Place suitable supply decoupling near the device.
- Route the interface selected in the customer configuration.
Pin Functions
The ATECC608C 8-SOIC pin functions are NC on pins 1, 2, 3 and 7; GND on pin 4; SDA on pin 5; SCL on pin 6; and VCC on pin 8. SDA and SCL behavior depends on the selected I2C or single-wire configuration. Confirm the programmed interface before host wiring.
Key Specifications
| Exact order code | ATECC608C-TCSMS |
|---|---|
| Manufacturer | Microchip Technology |
| Trust platform | TrustCUSTOM; customer-defined configuration and provisioning |
| Standard blank equivalent | ATECC608C-SSHDA according to Microchip variant table |
| Package | 8-lead SOIC; registered 8-SOIC (0.154", 3.90mm Width) |
| Host interface | I2C or single-wire as configured |
| Supply voltage | 2.0 V to 5.5 V per ATECC608C summary |
| I/O levels | 1.8 V to 5.5 V under specified conditions |
| Industrial temperature | -40°C to +85°C for Trust Platform SOIC option |
| Asymmetric engine | ECC P-256 ECDSA and ECDH |
| Additional cryptography | SHA-256, HMAC and AES-128 |
| Provisioned state | Must be established from the customer-specific manufacturing record |
Operational capabilities depend on configuration and locked slot permissions.
Replacement Considerations
Do not treat a blank TrustCUSTOM device as a drop-in substitute for a pre-provisioned Trust&GO or TrustFLEX part. Check the customer configuration, keys, certificates, interface, package and lifecycle. No unverified internal alternative link is included.
Manufacturer Information
Microchip's ATECC608C summary data sheet identifies ATECC608C-TCSMS as the TrustCUSTOM 8-pin SOIC ordering option and equates the standard blank form to ATECC608C-SSHDA. It describes TrustCUSTOM as a fully customizable configuration and customer-unique provisioning flow. Consult the complete manufacturer documentation and approved provisioning files for a particular deployment.
Applications
Provision customer-specific keys and certificates under an approved policy.
Design a signed-firmware workflow with appropriate host enforcement.
Configure protected challenge-response operations.
Integrate hardware ECDH into a complete secure protocol.
Quality & Authenticity
Verify the full -TCSMS code, marking, lot traceability and customer-specific configuration or provisioning record. The package image does not demonstrate identity or secure state. Test actual slot policy and cryptographic responses.
FAQ
Is this already provisioned like Trust&GO?
No such assumption is valid. TrustCUSTOM uses a customer-defined provisioning flow.
What package does S identify?
It identifies the 8-lead SOIC TrustCUSTOM option.
Which host interface is used?
Check the selected configuration; the ATECC608C family supports I2C and single-wire modes.
Is it a direct replacement for TrustFLEX?
No. Security policy, credentials and integration must be compared first.
Engineering Notice
Before release, review current Microchip documentation, electrical limits and errata. Validate approved configuration, secure provisioning, host software, certificate chain and threat model. A blank or misconfigured device cannot provide the intended authentication guarantee.
