SD products are low
capacity solid-state flash memory products
that complies with the SD Association
standard. Cactus SD products provide up
to 8GB of formatted storage capacity and
is designed to be used in applications
which requires reliable, high performance
solid state storage in a small form factor.
Cactus Technologies

Industrial Grade
SDChip
TM
provides up to 8GB of formatted
storage capacity in a small 23mm x 21mm
BGA form factor. It is designed to be used
in an environment which requires a
rugged, small form factor. By eliminating
the SD socket and soldering the SDChip
TM
directly onto the system board, shock and
vibration resistance is greatly increased as
compared to the standard SD card &
socket arrangement.

products use high quality
flash memory from well known vendors,
such as Toshiba Corporation. In addition,
they include an on-drive intelligent
controller that manages interface
protocols, data storage and retrieval as
well as ECC, defect handling & diagnostics,
power management, and clock control.

1.1. Supported Standards
Cactus Technologies
©
SD products are fully electrically compatible with the following
specification:
•
SD Card Association Physical Layer Specification, Versions 1.01, 1.1 and 2.0
1.2. Product Features
Cactus Technologies
©
Industrial SD products contain a high level, intelligent controller. This
intelligent controller provides many capabilities including the following:
•
•
•
•
•
SD Card register and command set handling.
Management of erasing and programming the flash memory independent of the host
system.
Sophisticated defect managing capabilities (similar to magnetic disk drives).
Sophisticated system for error recovery using powerful error correction code (ECC).
Intelligent power management for low power operation.
1.2.1.
Host and Technology Independence
Cactus Technologies
©
Industrial SD products utilize a 512-byte sector which is the same as
that in an IDE magnetic disk drive. To write or read a sector (or multiple sectors), the host
computer software simply issues a Read or Write command to the drive and then waits for
the command to complete. The host system does not need to know the details of how the
flash memory is erased, programmed or read, as this is all managed by the built-in controller
in the drive. Also, with the intelligent on-board controller, the host system software will not
need to be updated to match new flash technologies. Thus, systems that support the Cactus
Technologies
©
Industrial SD products today will continue to work with future Cactus
Technologies
©
Industrial SD products built with new flash technology without having to
update or change host software.
1.2.2.
Defect and Error Management
Cactus Technologies
©
Industrial SD products contain a sophisticated defect and error
management system similar to those found in magnetic disk drives. The defect management
is completely transparent to the host and does not consume any user data space.
The bit error rate for Cactus Technologies
©
Industrial SD products is much lower than that of
magnetic disk drives. When a read error does occur, the drive has sophisticated ECC to
recover the data.
These defect and error management systems, coupled with the solid-state construction, give
Cactus Technologies
©
Industrial SD products extremely high reliability.
