• Manufacturer: MCNIX [Macronix International]

QUERY COMMAND AND COMMON FLASH INTERFACE (CFI) MODE
MX29LV640D 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. A reset command is required to exit
CFI mode and go back to ready array mode or erase suspend mode. The system can write the CFI Query command
only when the device is in read mode, erase suspend, standby mode or automatic select mode.
