3347I–SEEPR–1/05
Functional
Description
The AT25080A/160A/320A/640A is designed to interface directly with the synchronous serial
peripheral interface (SPI) of the 6805 and 68HC11 series of microcontrollers.
The AT25080A/160A/320A/640A utilizes an 8-bit instruction register. The list of instructions
and their operation codes are contained in Table 5. All instructions, addresses, and data are
transferred with the MSB first and start with a high-to-low CS transition.
WRITE ENABLE (WREN): The device will power up in the write disable state when VCC is
applied. All programming instructions must therefore be preceded by a Write Enable
instruction.
WRITE DISABLE (WRDI): To protect the device against inadvertent writes, the Write Disable
instruction disables all programming modes. The WRDI instruction is independent of the sta-
tus of the WP pin.
READ STATUS REGISTER (RDSR): The Read Status Register instruction provides access to
the status register. The READY/BUSY and Write Enable status of the device can be deter-
mined 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.

Definition
Bit 0 (RDY)Bit 0 = “0” (RDY) indicates the device is READY. Bit 0 = “1” indicates the write cycle
is in progress.
Bit 1 (WEN)
Bit 1= “0” indicates the device is not WRITE ENABLED. Bit 1 = “1” indicates the
device is write enabled.
Bit 2 (BP0)
Bit 3 (BP1)
Bits 4–6 are “0”s when device is not in an internal write cycle.
Bit 7 (WPEN)
Bits 0–7 are “1”s during an internal write cycle.
