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 AT49F001(N) and
1C000H to 1FFFFH for the AT49F001(N)T.
3. Either one of the Product ID Exit commands can be used.
4. SA = sector addresses
For the AT49F001(N):
SA = 10000 to 1FFFF 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 AT49F001(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
Absolute Maximum Ratings*

*NOTICE:
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.
