AT25080A/160A/320A/640A
5082B–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 instruc-
tions 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 V
CC
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 indepen-
dent of the status 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 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.

Read Status Register Bit Definition
Bit
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)
See Table 8 on page 8.
Bit 3 (BP1)
See Table 8 on page 8.
Bits 4
6 are “0”s when device is not in an internal write cycle.
Bit 7 (WPEN)
See Table 9 on page 8.
Bits 0
7 are “1”s during an internal write cycle.
