1. The DATA FORMAT in each bus cycle is as follows: I/O7 - I/O0 (Hex)
2. The 16K byte boot sector has the address range 00000H to 03FFFH for the AT49BV/LV001(N) and
3. Either one of the Product ID Exit commands can be used.
4. SA = sector addresses:
AT49BV/LV001(N)(T)
1C000H to 1FFFFH for the AT49BV/LV001(N)T.
For the AT49BV/LV001(N):
SA = 00000 to 03FFF for BOOT BLOCK
Nothing will happen and the device goes back to the read mode in 100 ns
SA = 04000 to 05FFF for PARAMETER BLOCK 1
SA = 06000 to 07FFF for PARAMETER BLOCK 2
SA = 08000 to 0FFFF for MAIN MEMORY ARRAY BLOCK 1
This command will erase - PB1, PB2 and MMB1
SA = 10000 to 1FFFF for MAIN MEMORY ARRAY BLOCK 2
For the AT49BV/LV001(N)T:
SA = 1C000 to 1FFFF for BOOT BLOCK
Nothing will happen and the device goes back to the read mode in 100 ns
SA = 1A000 to 1BFFF for PARAMETER BLOCK 1
SA = 18000 to 19FFF for PARAMETER BLOCK 2
SA = 10000 to 17FFF for MAIN MEMORY ARRAY BLOCK 1
This command will erase - PB1, PB2 and MMB1
SA = 00000 to 0FFFF for MAIN MEMORY ARRAY BLOCK 2

Stresses beyond those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions beyond those indicated in the operational sec-
tions of this specification is not implied. Exposure to
absolute maximum rating conditions for extended
periods may affect device reliability.
