The Sector Erase command can be used to individually erase any sector in the main memory.
There are 4 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 5 don’t care bits, 7 page
address bits (PA9 - PA3) and 12 don’t care bits. To perform a sector 1-3 erase, the opcode 7CH
must be loaded into the device, followed by three address bytes comprised of 6 don’t care bits, 2
page address bits (PA8 - PA7) and 16 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 6 don’t care bits and 7 page address bits (A17 - A11) and
11 don’t care bits. To perform a sector 1-3 erase, the opcode 7CH must be loaded into the
device, followed by three address bytes comprised of 7 don’t care bit and 2 page address bits
(A16 - A15) 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
the part is busy.
