High-capacity memory tokens

24 November 2010 DSP, Micros & Memory

Datakey Electronics’ new High-Capacity line of portable memory tokens combines the high-capacity and high-throughput of consumer memory products like USB Flash drives/thumb drives and SD cards, with Datakey’s rugged packaging, reliable operation, unique form-factors and high cycle-life/harsh environment receptacles.

These features allow embedded system designers to incorporate high capacity memory devices into their designs, without the shortcomings that consumer-focused solutions bring.

The reprogrammable memory devices includes two families of memory tokens: the DFX series, which delivers a high-performance secure digital (SD) interface (including SPI); and the UFX series, which delivers a USB 2,0 high-speed interface. Both series come standard with 4 GB of non-volatile memory, with larger capacities (up to 32 GB) also available. With SPI, SD and USB interface options, these new memory tokens are easily integrated into embedded controller, single board computer and industrial PC designs, as many of these devices come standard with one or more of these serial interfaces. Integration is straightforward and is typically accomplished by simply adding one of Datakey’s industrial-rated mating receptacles.

Utilising Datakey’s robust SlimLine token form-factor design allows the DFX and UFX tokens to leverage the entire line of SlimLine receptacles, providing OEMs with a complete data-carrier system. The High Capacity line of receptacles features multiple mounting options including through-hole, surface-mount and panel-mount versions. Panel-mount options are available in IP65 (splash-proof), IP67 (immersion) and EMI reduction versions to meet the needs of harsh environment applications. All of the receptacles are rated for 50 000 cycles and withstand shock and vibration, extreme temperatures, humidity, salt-fog environments and exposure to various chemicals.

The memory tokens’ unique form-factor means that they cannot plug in to just any PC, which helps to protect the data on the token. This can also prevent consumer devices from plugging into the OEM system, which helps protect that system from unauthorised access and prevents malicious files (like viruses) from being uploaded. The token’s controlled availability virtually assures that only approved devices are used in the OEM system and provides the OEM with an additional revenue stream from the sale of memory tokens to their users.
