C670 / C670A Series CompactFlash Product Description

For embedded applications requiring maximum speed, high capacity or both, the Delkin C670 Series CompactFlash cards utilize a 4-channel UDMA 7 controller to deliver the fastest and largest capacity industrial temperature solutions on the market.  Cards are available in sizes up to 64GB SLC, delivering read speeds up to 150MB/s.

Voltage detection circuitry ensures that no updates to the flash occur below 2.7V, thereby protecting firmware and critical data from corruption.  SMART data is a valuable feature to monitor critical parameters of the card – including P/E cycles, bad blocks, spare blocks and estimated remaining life, for preventive maintenance purposes.

Delkin uses a smart part numbering system to control major BOM components, requiring a part number change if the controller, firmware or flash changes in a device.  A strong life cycle management program notifies customers in advance if a part number is being discontinued, with opportunities for last time buys and qualification of replacement parts.

Delkin specializes in customization of cards to meet individual customer needs – including custom labels, content & image loading, serialization, conformal coating and custom shock & vibration testing or mechanical adaptations to mitigate severe environmental conditions. Contact Delkin to find out how we can customize cards to meet your requirements.
