The Sector Erase command can be used to individually erase any sector in the main memory.
There are 8 sectors and only one sector can be erased at one time. To perform sector 0a or sec-
tor 0b erase for the DataFlash standard page size (264 bytes), an opcode of 7CH must be
loaded into the device, followed by three address bytes comprised of 4 don’t care bits, 8 page
address bits (PA10 - PA3) and 12 don’t care bits. To perform a sector 1-7 erase, the opcode
7CH must be loaded into the device, followed by three address bytes comprised of 4 don’t care
bits, 3 page address bits (PA10 - PA8) and 17 don’t care bits. To perform sector 0a or sector 0b
erase for the binary page size (256 bytes), an opcode of 7CH must be loaded into the device,
followed by three address bytes comprised of 5 don’t care bit and 8 page address bits (A18 -
A11) and 11 don’t care bits. To perform a sector 1-15 erase, the opcode 7CH must be loaded
into the device, followed by three address bytes comprised of 5 don’t care bit and 3 page
address bits (A18 - A16) and 16 don’t care bits. The page address bits are used to specify any
valid address location within the sector which is to be erased. When a low-to-high transition
occurs on the CS pin, the part will erase the selected sector. The erase operation is internally
self-timed and should take place in a maximum time of t
will indicate that the part is busy.
