COMMON FLASH INTERFACE (CFI)
The Common Flash Interface (CFI) specification is
a JEDEC approved, standardised data structure
that can be read from the Flash memory device.
CFI allows a system software to query the flash
device to determine various electrical and timing
parameters, density information and functions
supported by the device.
CFI allows the system to easily interface to the
Flash memory, to learn about its features and pa-
rameters, enabling the software to configure itself
when necessary.
Tables 12, 13, 14, 15, 16 and 17 show the address
used to retrieve each data.
The CFI data structure gives information on the
device, such as the sectorization, the command
set and some electrical specifications. Tables 12,
13, 14 and 15 show the addresses used to retrieve
each data. The CFI data structure contains also a
security area; in this section, a 64 bit unique secu-
rity number is written, starting at address 80h. This
area can be accessed only in read mode by the fi-
nal user and there are no ways of changing the
code after it has been written by ST. Write a read
instruction to return to Read mode.
Refer to the CFI Query instruction to understand
how the M28W800 enters the CFI Query mode.
Table 12. Query Structure Overview
Note: The Flash memory display the CFI data structure when CFI Query command is issued. In this table are listed the main sub-sections
detailed in Tables 13, 14, 15, 16 and 17. Query data are always presented on the lowest order data outputs.
Table 13. CFI Query Identification String
Note: Query data are always presented on the lowest - order data outputs (DQ7-DQ0) only. DQ8-DQ15 are ‘0’.
