GENERAL DESCRIPTION

The A25LS512A is 512K 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 one block, 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

512 pages, or 65,536 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.
