A25L80P
8 Mbit, Low Voltage, Serial Flash Memory
With 50 MHz SPI Bus Interface
GENERAL DESCRIPTION
The A25L80P is an 8 Mbit (1M x 8) 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 16 sectors, each containing 256
pages. Each page is 256 bytes wide. Thus, the whole memory
can be viewed as consisting of 4096 pages, or 1,048,576
bytes.
The whole memory can be erased using the Bulk Erase
instruction, or a sector at a time, using the Sector Erase
instruction.
