Data Sheet
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

10. WA = Address of memory location to be written
11. WD = Data to be written at location WA
12. Valid addresses for the User Security ID space are from FFFC 0188H to FFFC 019FH.
1. This value must be a valid address within the device Memory Address Space. X can be V
2. SST Manufacturer’s ID = BFH, is read with A
3. Following the Read-Software-ID/Read-Security-ID command, Read operations access manufacturer’s ID and Device ID or Security
4. IA = Device Identification Address/Security ID Address.
5. ID = Data read from identifier codes/Data read from Security ID
6. SRD = Data read from Status register
7. The sector or block must not be write-locked when attempting Erase or Program operations.
8. SA
9. The Program command operates on multiple bytes.
SST49LF016C Device ID = 5CH, is read with A
Following the Read-Software-ID/Read-Security-ID command,
Read operations access Manufacturer’s ID and Device ID or Security ID.
ID. Read-Software-ID/Read-Security-ID and Read-Status-Register will return register data until another valid command is written.
Attempts to issue an Erase or Program command to a write-locked sector/block will fail.
