COMMON FLASH MEMORY INTERFACE (CFI)
F49L160UA/F49L160BA
Elite Semiconductor Memory Technology Inc.
Publication Date : Dec. 2006
Revision: 1.3 19/51
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 backward- 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 in word
mode (or address AAh in byte mode), any time the device is ready to array data. The system can read CFI information at
the address given in Tables 8-10 in word mode, the upper address bits (A7-MSB) must be all zeros. To terminate reading
CFI data, the system must write the reset command.
The system can also write the CFI query command when the devices 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 8-10. The system must write the
reset command to return the device to the autoselect mode.
