Industrial SD models added to Datakey RUGGEDrive

ATEK Access Technologies has announced it has expanded its Datakey RUGGEDrive Line of USB flash drive and SD memory tokens with a new line of industrial models, providing industrial SD card functionality in the unique RUGGEDrive form factor.

The DFX memory tokens are said to add industrial temperature operation, a fixed bill of materials and SLC NAND flash capabilities.

The DFX models operate in industrial temperatures ranging from -40°C to 85°C, making it suitable for certain military, agriculture and industrial applications.

“The main components that make up an SD card are the controller IC, the firmware it runs and the NAND flash,” said Paul Plitzuweit, senior product manager for the Datakey line, pictured. “With consumer SD cards, these components can change from lot-to-lot, resulting in varying levels of performance and reliability.”

The memory tokens are available with either multi-level cell (MLC) or single-level cell (SLC) NAND flash. SLC NAND flash is said to have several advantages over MLC NAND flash, including increased program/erase cycles, faster write speeds, longer product life cycles and better unpowered data retention.
