GENERAL DESCRIPTION

The A25L20P/A25L10P/A25L05P are 2M/1M/512 bit Serial

Flash Memory, with advanced write protection mechanisms,

accessed by a high speed SPI-compatible bus.

pages. Each page is 256 bytes wide. Thus, the whole memory

can be viewed as consisting of 1024/512/256 pages, or 262,144

/131,072/65,536 bytes.

The whole memory can be erased using the Bulk 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 4/2/1 sectors, each containing 256
