Security functions

Function	Purpose
SD Key	Encrypts stored data and permits decryption through correct authentication.
Hidden Function	Restricts protected data so it can be read only after valid user authentication.
Write Protect	Keeps protected data read-only unless a verified user is authorized to modify it.

Security features and implementation details vary by configuration. Confirm host integration and authentication requirements with AMP.

Frequently Asked Questions

What is the difference between SD and microSD?

Both are removable flash-memory card formats, but microSD is physically smaller. The host must support the selected physical format, interface generation, capacity type and speed classification.

Which NAND options are available?

AMP lists QLC, TLC, MLC, pSLC and SLC options across the portfolio. The available NAND types and capacities differ between AMPSD, AMPMS and encrypted-card configurations.

What security features are available on encrypted cards?

Qualifying encrypted SD and microSD cards support SD Key authentication, a hidden-data function and verified-user write protection. Confirm the required host integration and feature implementation with AMP.

Are industrial-temperature cards available?

Yes. Commercial, extended and industrial options are listed across the portfolio. The exact operating range and grade must be confirmed for the selected series and part number.

What information should I provide with an SD or microSD inquiry?

Provide the required form factor, capacity, NAND type, speed class, UHS or video class, application-performance class, security requirements, operating temperature, host platform and estimated annual volume.
