CompactFlash Cards™

Do you have questions?

To this day, CompactFlash™ (CF) cards are still a very popular Flash based storage solution used in the embedded and industrial markets and the CompactFlash™ Card form factor and connector are well established. Swissbit‘s CF Cards were developed with strong focus on quality, reliability, robustness and longevity. We only select high-quality components and apply design rules fitting the stringent requirements of our customers. Hardware and firmware were tested and qualified by our experienced technical team and features and functionality have been proven in many challenging customer applications.

Swissbit‘s CF Series C-3×0, C-4×0 and C-5×0 are offered in both, commercial (0°C to 70°C) and industrial (-40°C to 85°C) temperature ranges, providing rugged and reliable memory for a wide range of demanding use cases. They are designed to solve a broad range of concerns from compatibility, booting and Power Fail Safety to long-term supply, controlled BOM and outstanding Flash protocol handling techniques to ensure highest possible data integrity. In contrast to commonly promoted sequential performance values, Swissbit is especially focused on optimized random access speed, one of the key requirements in legacy embedded CompactFlash applications.

The C-300 Longevity CF Card ensures optimized backward compatibility to legacy systems, high random access speed and a wide range of capacities from 32 MB to 8 GB using highly reliable SLC Flash with 100’000 program / erase cycles.

Swissbit’s most recent CF Card product families are C-500, C-50 and C-56 which are using page based Flash management and thus provide highest write IOPS rate as well as outstanding endurance

Product Features

Data Care Managment

Various effects like data retention, read disturb limits or temperature can impact data reliability. The latest generation of Swissbit products use special methods to maintain and refresh the data for higher data integrity.

ESD and EMI safe

The product designs are in line with the latest regulations for electrostatic discharge and electromagnetic interference. Swissbit strives to exceed these limits with our own in-house technology and production capabilities, for example with System-in-Package (SiP) competence.

Life time monitoring (LTM)

The Swissbit Life Time Monitoring feature enables users to access the memory device’s detailed Life Time Status and allows predicting imminent failure avoiding unexpected data loss. This feature uses an extended S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) interface or vendor specific commands to retrieve the Flash product information.

Longevity

The longevity product lines use special components with a long-term supply commitment of up to 10 years. These products offer lowest TCO in demanding applications with high requalification cost.

Power fail protection

Intelligent Power Fail Protection & Recovery protects data from unexpected power loss. During an unintentional shutdown, firmware routines and an intelligent hardware architecture ensure that all system and user data will be stored to the NAND.

Secure erase (Sanitize / Purge) / Fast erase

This feature uses an uninterruptable sequence of data erase commands. Even a power off can’t stop the process which will continue upon restoration of power. The optional enhanced feature allows the customer to sanitize the data according to different standards like DoD, NSA, IREC, etc. The purge algorithm can be started by a software command or through a hardware pin.

Shock and vibration

Robustness is one of our key specification targets. The design, assembly and use of selected materials guarantee an extremely solid design which has been validated by extensive testing.

Trim support

The TRIM command allows the operating system to inform the SSD which blocks of data are no longer considered in use and can be wiped out internally which increases system performance in following write accesses. With TRIM Support data scrap can be deleted in advance which otherwise would slow down future write operations to the involved blocks.

WAF reduction

The WAF (write amplification factor) for MLC based products is reduced by combining a paged based FW block management with a powerful card architecture and configuration settings.

Wear leveling

Sophisticated Wear Leveling & Bad Block Management ensure that Flash cells are sparingly and equally used in order to prolong life time of the device.

Wide temperature support

Swissbit‘s embedded memory & storage solutions are designed and approved for reliable operation over a wide temperature range. The products are verified at temperature corners and prestressed with a burn-in operating functional test (Test During Burn In – TDBI).
