AT49BV/LV002(N)(T)
5
Notes:
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/LV002(N) and 3C000H to 3FFFFH for
the AT49BV/LV002(N)T
3. Either one of the Product ID Exit commands can be used.
4. SA = sector addresses:
For the AT49BV/LV002(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 1FFFF for MAIN MEMORY ARRAY BLOCK 1
This command will erase - PB1, PB2 and MMB1
SA = 20000 to 3FFFF for MAIN MEMORY ARRAY BLOCK 2
For the AT49BV/LV002(N)T:
SA = 3C000 to 3FFFF for BOOT BLOCK
Nothing will happen and the device goes back to the read mode in 100 ns
SA = 3A000 to 3BFFF for PARAMETER BLOCK 1
SA = 38000 to 39FFF for PARAMETER BLOCK 2
SA = 20000 to 37FFF for MAIN MEMORY ARRAY BLOCK 1
This command will erase - PB1, PB2 and MMB1
SA = 00000 to IFFFF for MAIN MEMORY ARRAY BLOCK 2
