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 ID = BFH, is read with A
0
= 0,
SST29EE010 Device ID = 07H, is read with A
0
= 1.
SST29LE010/29VE010 Device ID = 08H, is read with A
0
= 1.
2. The device does not remain in Software Product ID Mode if powered down.
3. This device supports both the JEDEC standard three-byte command code sequence and SST’s original six-byte command code
sequence. For new designs, SST recommends the three-byte command code sequence be used.
