Working Principles

The SST38VF6402-90-5I-B3KE utilizes flash memory technology to store data. It consists of numerous memory cells that can be electrically programmed and erased. The device uses a parallel interface to communicate with the host system, allowing for fast data transfer.

During write operations, the memory cells are programmed by applying appropriate voltage levels to specific pins. Erase operations are performed at the sector level, where entire sectors of memory are cleared simultaneously. The stored data can be read by activating the read mode and accessing the desired memory address.
