MX29LV320E T/B
COMMON FLASH MEMORY INTERFACE (CFI) MODE
QUERY COMMAND AND COMMAND FLASH MEMORY INTERFACE (CFI) MODE
MX29LV320E T/B features CFI mode. Host system can retrieve the operating characteristics, structure and
vendor-specified information such as identifying information, memory size, byte/word configuration, operating
voltages and timing information of this device by CFI mode. The device enters the CFI Query mode when the
system writes the CFI Query command, 98H, to address 55h/AAh (depending on Word/Byte mode) any time the
device is ready to read array data. The system can read CFI information at the addresses given in Table 4.
Once user enters CFI query mode, user can not issue any other commands except reset command. The reset
command is required to exit CFI mode and go back to the mode before entering CFI. The system can write the
CFI Query command only when the device is in read mode, erase suspend, standby mode or automatic select
mode. The CFI unused area is Macronix's reserved.
