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 commands are summarized in
the text descriptions below.
Read/Reset command
The Read/Reset command returns the memory to its Read mode where it behaves like a
ROM or EPROM. 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.
If the Read/Reset command is issued during a Block Erase operation or following a
Programming or Erase error then the memory will take upto 10
period no valid data can be read from the memory. Issuing a Read/Reset command during a
Block Erase operation will leave invalid data in the memory.
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 another command is issued.
From the Auto Select mode the Manufacturer code can be read using a Bus Read operation
with A0 = V
Manufacturer code for STMicroelectronics is 20h.
The Device code can be read using a Bus Read operation with A0 = V
other address bits may be set to either V
20h.
The Block Protection status of each block can be read using a Bus Read operation with A0
= V
may be set to either V
Data Inputs/Outputs, otherwise 00h is output.
