AT25080B/160B

Functional Description
The AT25080B/160B is designed to interface directly with the synchronous serial peripheral interface (SPI) of the
6805 and 68HC11 series of microcontrollers.
The AT25080B/160B utilizes an 8-bit instruction register. The list of instructions and their operation codes are con-
tained in Table 3-1 . 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 program-
ming 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 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
Definition
Bit 0 = “0” (RDY) indicates the device is READY. Bit 0 = “1” indicates the write cycle is in progress
Bit 1= “0” indicates the device is not WRITE ENABLED. Bit 1 = “1” indicates the device is write enabled
See Table 3-4 on page 8
See Table 3-4 on page 8
Bits 4–6 are “0”s when device is not in an internal write cycle
Bit 7 (WPEN)
See Table 3-5 on page 8
Bits 0–7 are “1”s during an internal write cycle
