PRODUCT DESCRIPTION

SST’s ATA Flash Disk Controller is the heart of a high performance, flash media-based data storage system.

The ATA Flash Disk Controller recognizes the control, address, and data signals on the ATA/IDE bus and trans lates them into memory accesses to the standard NAND type flash media. The SST55LD019M device supports Multi-Level Cell (MLC) and high density Single-Level Cell (SLC) flash media. This technology suits solid state mass storage applications offering new, expanded functionality while enabling smaller, lighter designs with lower power consumption.
