Command Interface
All Bus Write operations to the memory are interpreted by the Command Interface.
Commands consist of one or more sequential Bus Write operations. Failure to observe a
valid sequence of Bus Write operations will result in the memory returning to Read mode.
The long command sequences are imposed to maximize data security.
The address used for the commands changes depending on whether the memory is in 16-
bit or 8-bit mode. See either
used, for a summary of the commands.
Read/Reset command
The Read/Reset command returns the memory to its Read mode where it behaves like a
ROM or EPROM, unless otherwise stated. It also resets the errors in the Status Register.
Either one or three Bus Write operations can be used to issue the Read/Reset command.
The Read/Reset Command can be issued, between Bus Write cycles before the start of a
program or erase operation, to return the device to read mode. Once the program or erase
operation has started the Read/Reset command is no longer accepted. The Read/Reset
command will not abort an Erase operation when issued while in Erase Suspend.
Auto Select command
The Auto Select command is used to read the Manufacturer Code, the Device Code and the
Block Protection Status. Three consecutive Bus Write operations are required to issue the
Auto Select command. Once the Auto Select command is issued the memory remains in
Auto Select mode until a Read/Reset command is issued. Read CFI Query and Read/Reset
commands are accepted in Auto Select mode, all other commands are ignored.
From the Auto Select mode the Manufacturer Code can be read using a Bus Read operation
with A0 = V
Manufacturer Code for STMicroelectronics is 0020h.
The Device Code can be read using a Bus Read operation with A0 = V
other address bits may be set to either V
