Due to the size of the package, the Micron-standard part number is not printed on the top of the device. Instead,
an abbreviated device mark consisting of a 5-digit alphanumeric code is used. The abbreviated device marks are
cross-referenced to the Micron part numbers at the FBGA Part Marking Decoder site: www.micron.com/decoder.

Critical Applications. Products are not authorized for use in applications in which failure of the Micron compo-
nent could result, directly or indirectly in death, personal injury, or severe property or environmental damage
("Critical Applications"). Customer must protect against death, personal injury, and severe property and environ-
mental damage by incorporating safety design measures into customer's applications to ensure that failure of the
Micron component will not result in such harms. Should customer or distributor purchase, use, or sell any Micron
component for any critical application, customer and distributor shall indemnify and hold harmless Micron and
its subsidiaries, subcontractors, and affiliates and the directors, officers, and employees of each against all claims,
costs, damages, and expenses and reasonable attorneys' fees arising out of, directly or indirectly, any claim of

applications, and products using Micron products. ALL SEMICONDUCTOR PRODUCTS HAVE INHERENT FAIL-
URE RATES AND LIMITED USEFUL LIVES. IT IS THE CUSTOMER'S SOLE RESPONSIBILITY TO DETERMINE
WHETHER THE MICRON PRODUCT IS SUITABLE AND FIT FOR THE CUSTOMER'S SYSTEM, APPLICATION, OR
PRODUCT. Customers must ensure that adequate design, manufacturing, and operating safeguards are included
in customer's applications and products to eliminate the risk that personal injury, death, or severe property or en-
vironmental damages will result from failure of any semiconductor component.
Limited Warranty. In no event shall Micron be liable for any indirect, incidental, punitive, special or consequential
damages (including without limitation lost profits, lost savings, business interruption, costs related to the removal

General Description

General Description
Micron universal flash storage (UFS) is a communication and mass data storage device
that includes an M-PHY interface, one or more NAND Flash components, and a con-
troller on an advanced 6-signal bus, which is compliant with the UFS system specifica-
tion. Its cost per bit, small package sizes, and high reliability make it an ideal choice for
automotive applications, including information and entertainment, navigation tools,
advanced driving assistance systems, and a variety of other industrial and portable
products.
The nonvolatile UFS draws no power to maintain stored data, delivers high perform-
ance across a wide range of operating temperatures, and resists shock and vibration dis-
ruption.

UFS Descriptors

UFS Descriptors
Descriptors are blocks or pages of parameters that describe something about the de-
vice. Descriptors are classified into types: device descriptors, configuration descriptors,
unit descriptors, and so forth. Micron devices support the following UFS descriptors.

c) if the XOR control mode page is not implemented, then the
maximum transfer length in blocks that the device server ac-
cepts for a single XDWRITE command or XDREAD command.

COUNT unmapped by an UNMAP command.

the value in this field shall be greater than or equal to 1.
1Ch 31:0 OPTIMAL UNMAP GRAN- 1h This field indicates the optimal granularity in logical blocks for

ularity is not specified.
20h 30:0 UNMAP GRANULARITY 0h This field indicates the LBA of the first logical block to which

Optimal unmap request starting LBA = (n × OPTIMAL UNMAP
GRANULARITY) + UNMAP GRANULARITY ALIGNMENT
Where n is 0 or any positive integer value.
