Absolute Maximum Ratings*
Temperature Under Bias................................ -55°C to +125°C
*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.
Storage Temperature..................................... -65°C to +150°C

Command Definition (in Hex)
(1)
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 3C000H to 3FFFFH.
3. Either one of the Product ID Exit commands can be used.
4. SA = sector addresses:
SA = 3C000 to 3FFFF for BOOT BLOCK
If the boot block is not locked out, this command will erase - BOOT BLOCK, PB1, PB2 and MMB1
If the boot block is locked out, 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
If the boot block is not locked out, this command will erase - BOOT BLOCK, PB1, PB2 and MMB1
If the boot block is locked out, this command will erase - PB1, PB2 and MMB1
SA = 00000 to IFFFF for MAIN MEMORY ARRAY BLOCK 2
