DEVICE COMMANDS
Device operation is controlled by commands written to the
Command User Interface (CUI). Execution of a specific
command is handled by internal functions after a CUI
receives and processes the command. After power-up or a
Reset operation the device enters Read mode. Commands
consist of one or two sequential Bus-Write operations. The
commands are summarized in Table 8, “Software Com-

2. SST Manufacturer’s ID = BFH, is read with A19-A0 = 0.
SST49LF004C/008C Device ID = 54H/59H, is read with A19-A1 = 0, A0 = 1.
Following the Read-Software-ID/Read-Security-ID command,
Read operations access Manufacturer’s ID and Device ID or Security ID.
3. Read-Software-ID/Read Security ID and Read Status Register will return ID/Register data until another valid command is written.
4. Following the Read-Software-ID/Read-Security-ID command, Read operations access manufacturer’s ID and Device ID or Security
ID. Read-Software-ID/Read-Security-ID and Read-Status-Register will return register data until another valid command is written.
