1. Introduction
The
Industrial 2.5” PATA (IDE) SSD products are designed to follow ATA/ATAPI-6 standard. The main used Flash
memories are Samsung SLC-NAND Type Flash memory chips from 128MB up to 8GB, and Micron SLC-NAND Type
Flash memory chips for 16GB only. The operating temperature grade is optional for standard grade 0°C ~ 70°C and
industrial grade -40°C ~ +85°C. The Industrial 2.5” PATA (IDE) SSD are designed electrically compliant with the
conventional IDE hard disk and support True IDE Mode. The data transfer modes supports PIO 0~4, MWDMA 0~2, or
UDMA 0~4; Default setting are PIO mode-4 or UDMA-4. 2.5” PATA (IDE) SSD features an extremely light weight, reliable,
low-profile form factor.
The Industrial 2.5” PATA (IDE) SSD provides a high level interface to the host computer. This interface allows a host
computer to issue commands to the SSD to read or write blocks of memory. The host addresses the card in 512 byte
sectors. Each sector is protected by a powerful 4 bits Error Correcting Code (ECC). The
Industrial 2.5” PATA (IDE) SSD,
it uses intelligent controller which manages interface protocols, data storage and retrieval as well as ECC, defect handling
and diagnostics, power management and clock control.
Figure 1 shows a block diagram of the used high tech Industrial 2.5” PATA (IDE) SSD controller.
