The software chip erase function is not supported by the industrial temperature part.
Please contact SST, if you require this function for an industrial temperature part.
Notes for Software Product ID Command Code:
1. With A
14
-A
1
=0; SST Manufacturer Code = BFH, is read with A
0
= 0,
29EE010 Device Code = 07H, is read with A
0
= 1.
29LE010/29VE010 Device Code = 08H, is read with A
0
= 1.
2. The device does not remain in Software Product ID Mode if powered down.
