FlashUFS

Long-Term Support
World Class Quality

Managed NAND Solutions for theAutomotive, Industrial, & Medical Markets

Key Features:• Low Voltage Differential Signaling (LVDS) signaling• High Performance with High-Speed Serial Interface• Full-duplex interface supporting simultaneous read and write• Low Energy Consumption

Product Description:
UFS is an advanced storage interface ideal for applications
requiring high-performance and low power consumption.
UFS is an open standard defined by JEDEC and incorporates
standards from the Mobile Industry Processor Interface(MIPI) alliance. UFS utilizes the well-known Small Computer
System Interface (SCSI) Architecture Model and commandprotocols that support multiple simultaneous commands
and command queuing features to enable highly efficient
multi-thread programming. UFS improves read and write
performance of flash memory in two ways. First, unlike
eMMC, there are dedicated channels for reading andwriting data allowing for simultaneous read/write dataflow. The second advantage of UFS is Command Queuing,
the efficient grouping and reordering of read or write
commands, to maximize the performance throughput.
ISSI’s UFS product family provides the ideal embeddedstorage solution for the Automotive, Industrial, Medical,LVDS Serial Interface
ReadUFSHost• Reliable advanced physical, link, and command protocollayers• Supports advanced features like Deep Sleep, Write Booster,
Host Performance Booster (HPB2.0), and Throttling
notifications to the host
• Security Features• UFS 2.1 and 3.1 interface• Density: 64GB to 256GB• Automotive Grade Qualified

Networking, and Consumer applications, which require highperformance, endurance, and low power across a wide rangeof operating temperatures, and long-term support. Theseproducts are available in Industrial as well as Automotivegrade. ISSI’s UFS integrates NAND flash memory and an
intelligent UFS controller in a single small formfactor BGApackage. The controller implements all the algorithms forreliable NAND flash management in addition to all the UFS
functionality and advanced features. ISSI’s UFS products
are optimized for efficient throughput, system performanceand reliability, delivering superior sequential and random
read/write performance, while offering near zero idle power
consumption.
ISSI’s UFS solution includes both the UFS 2.1 (uses 1.8V IOVoltage) devices, and the UFS 3.1 (uses 1.2V IO Voltage)
devices. The UFS 3.1 products support advanced data refreshand temperature notification features for superior system
reliability for automotive applications.
