GENERAL DESCRIPTION
The A25LQ080 is 8M bit Serial Flash Memory, with advanced
write protection mechanisms, accessed by a high speed
SPI-compatible bus.
sectors. Each sector is composed of 16 pages. Each page is
256 bytes wide. Thus, the whole memory can be viewed as
consisting of 4,096 pages, or 1,048,576 bytes.
The whole memory can be erased using the Chip Erase
instruction, a block at a time, using Block Erase instruction, or a
sector at a time, using the Sector Erase instruction.
The memory can be programmed 1 to 256 bytes at a time,
using the Page Program instruction.
The memory is organized as 16 blocks, each containing 16
