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 AT49F002(N) and 3C000H to 3FFFFH for the
3. Either one of the Product ID Exit commands can be used.
4. SA = sector addresses:
AT49F002(N)T
For the AT49F002(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 AT49F002(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

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.
