Common Flash Memory Interface
The Common Flash Interface (CFI) specification outlines device and host system software interrogation
handshake, which allows specific vendor-specified software algorithms to be used for entire families of
devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and back-
ward-compatible for the specified flash device families. Flash vendors can standardize their existing
interfaces for long-term compatibility.
This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address
55h any time the device is ready to read array data. The system can read CFI information at the addresses
given in Tables 12.6–12.8). All reads outside of the CFI address range, returns non-valid data. Reads from
other sectors are allowed, writes are not. To terminate reading CFI data, the system must write the reset
command.
The system can also write the CFI query command when the device is in the autoselect mode. The device
enters the CFI query mode, and the system can read CFI data at the addresses given in Tables 12.6–12.8.
The system must write the reset command to return the device to reading array data.
The following is a C source code example of using the CFI Entry and Exit functions. Refer to the Spansion
Low Level Driver User’s Guide (available on www.spansion.com) for general information on Spansion Flash
memory software development guidelines.
/* Example: CFI Entry command */
*( (UINT16 *)base_addr + 0x55 ) = 0x0098;
/* write CFI entry command
*/
/* Example: CFI Exit command
*/
*( (UINT16 *)base_addr + 0x000 ) = 0x00F0;
/* write cfi exit command
*/
For further information, please refer to the CFI Specification (see JEDEC publications JEP137-A and
JESD68.01and CFI Publication 100). Please contact your sales office for copies of these documents.
