Data Sheet
Memory Organization
The SST25VF512 SuperFlash memory array is organized in 4 KByte sectors with 32 KByte overlay
blocks.
Device Operation
The SST25VF512 is accessed through the SPI (Serial Peripheral Interface) bus compatible protocol.
The SPI bus consist of four control lines; Chip Enable (CE#) is used to select the device, and data is
accessed through the Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK).
The SST25VF512 supports both Mode 0 (0,0) and Mode 3 (1,1) of SPI bus operations. The difference
between the two modes, as shown in Figure 2, is the state of the SCK signal when the bus master is in
Stand-by mode and no data is being transferred. The SCK signal is low for Mode 0 and SCK signal is
high for Mode 3. For both modes, the Serial Data In (SI) is sampled at the rising edge of the SCK clock
signal and the Serial Data Output (SO) is driven after the falling edge of the SCK clock signal.
