Notes:
(1) Address format A14-A0 (Hex), Addresses A15 and A16 are a “Don’t Care”.
(2) Page Write consists of loading up to 128 bytes (A6 - A0).
(3) Alternate 6 byte software Product-ID Command Code
(4) 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 A14 -A1 =0; SST Manufacturer Code = BFH, is read with A0 = 0,
29EE010 Device Code = 07H, is read with A0 = 1.
29LE010/29VE010 Device Code = 08H, is read with A0 = 1.
2. The device does not remain in Software Product ID Mode if powered down.
