FEATURES
GENERAL DESCRIPTION
ꢀ 8 Mbit of Flash Memory
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.
ꢀ Flexible Sector Architecture (4/4/8/16/32)KB/64x15 KB
ꢀ Bulk Erase (8 Mbit) in 10s (typical)
ꢀ Sector Erase (512 Kbit) in 1s (typical)
ꢀ Page Program (up to 256 Bytes) in 3ms (typical)
ꢀ 2.7 to 3.6V Single Supply Voltage
ꢀ SPI Bus Compatible Serial Interface
ꢀ 50MHz Clock Rate (maximum)
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.
ꢀ Deep Power-down Mode 1µA (typical)
ꢀ Electronic Signature
The whole memory can be erased using the Bulk Erase
instruction, or a sector at a time, using the Sector Erase
instruction.
