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 - A18 (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.
4. Either one of the Product ID Exit commands can be used.
5. SA = sector addresses:
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
SA = 40000 to 4FFFF for MAIN MEMORY ARRAY BLOCK 5
SA = 50000 to 5FFFF for MAIN MEMORY ARRAY BLOCK 6
SA = 60000 to 6FFFF for MAIN MEMORY ARRAY BLOCK 7
SA = 70000 to 7FFFF for MAIN MEMORY ARRAY BLOCK 8

*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.
