Compact Flash for Embedded Systems
Adding a solid state storage device to an embedded computer has never been easier. With Serial ATA support, the A1203-ADA-CF3 adapter allows system builders to use a CompactFlash card anywhere a SATA disk can be used. A jumper is provided to drive standard panel indicator activity LEDs. When a CompactFlash card is installed in the socket the host computer ‘sees’ a standard ATA type mass-storage device.
Write Protect Feature
The A1203-ADA-CF3 adapter also provides a hardware write protection function that cannot be overridden. Users can choose between an on-board slider switch, or supply their own off-board switch through a standard 2-wire header, for example to provide a panel mounted switch. An indicator LED is mounted next to the on-board write protect switch to allow for visual confirmation of write protection. Once the write function is engaged, the host system will see the disk as a read-only device, and any attempt to write to the media will generate an error. Some example applications include pre-loading a bootable image for a system that needs to resist tampering, such as kiosk systems.
Applications:
- Protected pre-loaded boot image for kiosk computers and public terminals.
- Compliance with data-handling rules such as ensuring that runtime and user data is not stored on the boot media.
