A25L020C Datasheet PDF - AMIC Technology

GENERAL DESCRIPTION
   The A25L020C is 2M 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 4 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 1024 pages, or 262,144 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.
