GENERAL DESCRIPTION
The A25L032 is 32M bit Serial Flash Memory, with advanced
write protection mechanisms, accessed by a high speed
SPI-compatible bus.
The memory can be programmed 1 to 256 bytes at a time,
using the Page Program instruction.
The memory is organized as 64 blocks, each containing 16
sectors. Each sector is composed of 16 pages. Each page is
256 bytes wide. Thus, the whole memory can be viewed as
consisting of 16,384 pages, or 4,194,304 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.
