with several different combinations of features (see
Figure 3: Part Number Chart
NOTE:
1. Contact factory for availabilty.
2. Contact factory for details.
3. Burst mode specifications in the referenced Flash discrete data sheet are not guaranteed.
Valid Part Number Combinations
After building the part number from the part num-
ber chart above, please go to Micron’s Part Marking
Decoder Web site at www.micron.com/decoder to ver-
ify that the part number is offered and valid. If the
device required is not on this list, please contact the
factory.
Device Marking
Due to the size of the package, the Micron standard
part number is not printed on the top of each device.
Instead, an abbreviated device mark comprised of a
five-digit alphanumeric code is used. The abbreviated
device marks are cross-referenced to the Micron part
numbers at www.micron.com/decoder. To view the
location of the abbreviated mark on the device, please
refer to customer service note CSN-11, “Product Mark/
