AT49F002A(N)(T)
Notes:
1. The DATA FORMAT in each bus cycle is as follows: I/O7 - I/O0 (Hex). The address format in each bus cycle is as follows:
A11 - A0 (Hex); A11 - A17 (don’t care).
2. Since A11 is don’t care, AAA can be replaced with 2AA.
3. The 16K byte boot sector has the address range 00000H to 03FFFH for the AT49F002A(N) and 3C000H to 3FFFFH for the
AT49F002A(N)T
4. Either one of the Product ID Exit commands can be used.
5. SA = sector addresses:
For the AT49F002A(N):
SA = 00000 to 03FFF for BOOT BLOCK
SA = 04000 to 05FFF for PARAMETER BLOCK 1
SA = 06000 to 07FFF for PARAMETER BLOCK 2
SA = 08000 to FFFF for MAIN MEMORY ARRAY BLOCK 1
SA = 10000 to 1FFFF for MAIN MEMORY ARRAY BLOCK 2
SA = 20000 to 2FFFF for MAIN MEMORY ARRAY BLOCK 3
SA = 30000 to 3FFFF for MAIN MEMORY ARRAY BLOCK 4
For the AT49F002A(N)T:
SA = 3C000 to 3FFFF for BOOT BLOCK
SA = 3A000 to 3BFFF for PARAMETER BLOCK 1
SA = 38000 to 39FFF for PARAMETER BLOCK 2
SA = 30000 to 37FFF for MAIN MEMORY ARRAY BLOCK 1
SA = 20000 to 2FFFF for MAIN MEMORY ARRAY BLOCK 2
SA = 10000 to 1FFFF for MAIN MEMORY ARRAY BLOCK 3
SA = 00000 to 0FFFF for MAIN MEMORY ARRAY BLOCK 4
