4. Memory Array
To provide the greatest flexibility, the memory array of the AT25DF512C can be erased in three levels of granularity
including a full chip erase. The size of the erase blocks is optimized for both code and data storage applications, allowing
both code and data segments to reside in their own erase regions. The Memory Architecture Diagram illustrates the
breakdown of each erase level.

5. Device Operation
The AT25DF512C is controlled by a set of instructions that are sent from a host controller, commonly referred to as the
SPI Master. The SPI Master communicates with the AT25DF512C via the SPI bus which is comprised of four signal lines:
Chip Select (CS), Serial Clock (SCK), Serial Input (SI), and Serial Output (SO).
The SPI protocol defines a total of four modes of operation (mode 0, 1, 2, or 3) with each mode differing in respect to the
SCK polarity and phase and how the polarity and phase control the flow of data on the SPI bus. The AT25DF512C
supports the two most common modes, SPI Modes 0 and 3. The only difference between SPI Modes 0 and 3 is the
polarity of the SCK signal when in the inactive state (when the SPI Master is in standby mode and not transferring any
data). With SPI Modes 0 and 3, data is always latched in on the rising edge of SCK and always output on the falling edge
of SCK.
