Delkin’s USB Disk on Module is based on a USB 2.0 controller with an interface to NAND flash Memory. This flash USB module is ideal for single board computer applications, and its use will reduce the R/D to production cycle. It supports USB Mass Storage function and USB boot function from BIOS. This module is easy to install, easy to use and highly reliable. It is a solution to replace hard drives in embedded and computerized systems that require rugged, highly reliable, fast storage. Delkin manufactures its industrial and extended temperature grade USB DOM in the USA. Delkin OEM customers have the assurance of a controlled BoM.

• USB Disk on Module is based on ubiquitous, proven solid state mass storage and USB technology
• Cost effective compared to hard disks
• Provides ATA/IDE hard disk drive functionality, protocol, and compatibility in a single device with solid state flash drive
• Requires no additional or proprietary software –using the standard ATA driver means no additional BIOS and OS modification is required
• Complies with Standard ATA Interface
• Compatible with IDE Interface (40pin / 44pin)
• Capacity:16MB ~ 8GB
• Extremely Low Seek Time
• No Latency Delay
• Higher Shock Tolerance than HDD

The ATA-Disk Module

The ATA-Disk Module (ADM) is a solid-state disk drive that is designed to replace a conventional IDE hard disk drive and can be plugged into a standard IDE connector commonly found in desktop or portable PC systems. The ADM has a built-in micro controller and file management firmware that communicates with ATA standard interfaces; therefore, it does not require additional or proprietary host software such as Flash File System (FFS) or Memory Technology Driver (MTD) software. The ADM uses a standard ATA driver that is part of all major operating systems such as Windows 95/98/2000/NT/CE/XP, MAC, UNIX, LINUX, etc.

The ADM is designed to work at either 5V or 3.3V and is available in 32MB to 4GB capacities. It integrates a standard 40-pin or 44-pin female connector for easy and cost effective mounting on top of the standard IDE male connector commonly found on system motherboards. ADM also offers user selectable Master/Slave operation through an external jumper setting.

Every ATA-Disk Module comes with a factory-programmed, 20 Byte long, unique identification number for extended data protection. This feature prevents unauthorized duplication by allowing encryption of customer data.
