Micron has announced a new SPI NOR device MT35X (XTRMFlash).
This device's manufacturer ID is using 2Ch which arranged by
JEDEC. The 20h is also Micron's ID due to the history.
This new device support high speed I/O interface. The clock
frequency could up to 200 MHz (MAX) in DDR (400 MB/s) with
DQS. The device bus width could be 1 or 8, and it's default
width is configurable.
