(2) Page Write consists of loading up to 128 bytes (A6 - A0). (3) Alternate six-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, SST29EE010A Device Code = 22H, is read with A0 = 1. SST29LE010A/29VE010A Device Code = 23H, is read with A0 = 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. 303 PGM T4.0 |
