Data Sheet
Memory Organization
The SST25VF064C SuperFlash memory array is organized in uniform 4 KByte erasable sectors with
32 KByte overlay blocks and 64 KByte overlay erasable blocks.
Device Operation
The SST25VF064C is accessed through the SPI (Serial Peripheral Interface) bus compatible protocol.
The SPI bus consists 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 SST25VF064C 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 3, 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.

Reset/Hold Mode
The RST#/HOLD# pin provides either a hardware reset or a hold pin. From power-on, the RST#/
HOLD# pin defaults as a hardware reset pin (RST#). The Hold mode for this pin is a user selected
option where an EHLD instruction enables the Hold mode. Once selected as a hold pin (HOLD#), the
RST#/HOLD# pin will be configured as a HOLD# pin, and goes back to RST# pin only after a power-off
and power-on sequence.
