Description
The A25L512O-UF is a 16M bit Serial Flash Memory IC chip with advanced write protection mechanisms. It is accessed by a high-speed SPI-compatible bus and can be programmed 1 to 256 bytes at a time using the Page Program instruction. The memory is organized into 32 blocks, each containing 16 sectors. Each sector consists of 16 pages, with each page being 256 bytes wide. This results in a total memory size of 8,192 pages or 2,097,152 bytes. The memory can be erased using the Chip Erase instruction, block by block using the Block Erase instruction, or sector by sector using the Sector Erase instruction.
