General Description
STEC’s MACH4 CompactFlash (CF) card is an extremely high-performance,
multi-channel solution available in capacities from 8GB to 16GB using SLC
NAND flash and 8GB to 32GB using MLC NAND flash. The standard
CompactFlash interface provides designers with a true plug-n-play storage
device, allowing for short design cycles and fast time to market, while the
extreme performance enables hard disk drive performance in a much smaller
and more reliable design.
CompactFlash cards have quickly become the product of choice for
applications requiring high reliability and high tolerance to shock, vibration,
humidity, altitude, and temperature. Because the MACH4 CompactFlash uses
NAND flash technology (e.g. no moving parts), it is more reliable and has
much lower latency compared to a traditional hard disk drive and consumes far
less power (approximately 1 watt compared to 12 watts for a standard
7200rpm ATA disk drive). With its small footprint, high capacity, and
throughput up to 90 megabytes per second*, the MACH4 CompactFlash is an
ideal hard disk drive replacement or alternate storage solution in space-
constrained applications or those requiring less capacity than available hard
disk drives offer including blade servers and embedded PCs.
STEC’s MACH4 CF Card is available in a CompactFlash Type I package and
adheres to the latest industry compliance and regulatory standards including
UL, FCC, RoHS, and the Compact Flash Association (CFA). Because the
MACH 4 CF incorporates a proprietary state-of-the-art flash memory controller,
it that provides the greatest flexibility to customer-specific applications while
supporting key flash management features resulting in the industry’s highest
reliability and endurance. Key features include:
Full datapath protection with built-in 8-bit BCH ECC engine to detect and
correct up to 8-bit errors per 512 Bytes of data
Sophisticated bad block management and wear leveling algorithms
dramatically enhance flash memory endurance
Power-down data protection ensures data integrity in case of power loss
Lifecycle management feature allows users to monitor the card's lifetime by
monitoring the card's remaining spare blocks
STEC’s MACH 4 CF card offers the highest reliability and tolerance to shock,
vibration, humidity, altitude, ESD, and temperature. The rugged industrial
design combined with temperature testing and adherence to rigid JEDEC
JESD22 standards ensures flawless execution in the harshest environments.
In addition to custom hardware and firmware designs, STEC also offers value-
added services including:
Custom labeling and packaging
Custom software imaging and ID strings
Full BOM control and product change notification
Total supply-chain management to ensure continuity of supply
In-field application engineering to help customers through product design-ins
* Actual throughput may vary depending on hosts system and configuration; all
performance numbers are based on card being configured in TrueIDE mode
with UDMA-6 supported.
