Functional
Description
The AT25F2048 is designed to interface directly with the synchronous serial peripheral
interface (SPI) of the 6800 type series of microcontrollers.
The AT25F2048 utilizes an 8-bit instruction register. The list of instructions and their
operation codes are contained in Table 4. All instructions, addresses, and data are
transferred with the MSB first and start with a high-to-low transition.
Write is defined as program and/or erase in this specification. The following commands,
Program, Sector Erase, Chip Erase, and WRSR are write instructions for AT25F2048.

WRITE ENABLE (WREN): The device will power up in the write disable state when V CC
is applied. All write instructions must therefore be preceded by the WREN instruction.
WRITE DISABLE (WRDI): To protect the device against inadvertent writes, the WRDI
instruction disables all write commands. The WRDI instruction is independent of the sta-
tus of the WP pin.
READ STATUS REGISTER (RDSR): The RDSR instruction provides access to the sta-
tus register. The Ready/Busy and write enable status of the device can be determined
by the RDSR instruction. Similarly, the Block Write Protection bits indicate the extent of
protection employed. These bits are set by using the WRSR instruction. During internal
write cycles, all other commands will be ignored except the RDSR instruction.
