Vehicles are getting advanced day by day due to the introduction of central computing car systems just to enhance the user experience. Now, the car infotainment system is advancing to the next level by providing a high level of map navigation, video recordings, and multimedia control. With this rapid transformation in vehicles, the automotive industry demands safer, faster, robust, and highly capacitive memory fixtures. Acknowledging this increasing demand, Longsys launched the reliable version of automotive UFS to deal with all the emerging challenges of the automotive industry. It is supporting vehicle manufacturers by providing compact car-grade memory solutions.

The Interface Design of Automotive UFS

Automotive UFS is a universal flash storage designed to provide an excellent level of endurance and durability to modern applications. FORESEE has designed its interface by considering the application's needs to outperform the performance of eMMC. These chips are built on the UFS 2.1 standard interface that assures smooth data transmission and is made to tolerate harsh working operations. This 2.1 UFS protocol guarantees a higher 6Gbps bandwidth and higher signal integrity which makes it superior to earlier memory units.

The standard architecture of car-grade UFS is defined by JEDEC to provide versatile compatibility options for distinct applications. These car-grade chips stand alone in the market as they support advanced algorithms to optimize speed and performance. A high level of security protocols is used to allow the user to securely manage the data. There is no compromise over data integrity, data consistency, and stability. It is built to support connected automotive applications in terms of higher performance, increased capacity, and improved power efficiency. Its main functions involve high-speed writing, wide-temperature operation, or quick response to commands.

Technical Specifications

FORESEE automotive UFS works with 3D NAND and LPDC algorithms to strengthen the potential of heavy applications. The ADAS, ICS, EDR, IVI, DVR, camcorder, AVM, and multimedia systems use the automotive UFS to quickly perform real-time data collection and data processing. The write booster technique is used to enable this chip to reach the maximum write performance of up to 45K IOPS. These chips are made to focus on fast booting time, higher bandwidth, higher data acceleration, and quick response to commands. Some of its key specifications are:

How does Automotive UFS differ from Existing Standards?

The memory industry revolves around memory fixtures that provide higher storage capacity, unbeatable performance, fast data speed, higher durability, and faster P.E. cycles. Out of all the memory solutions, eMMC is greatly used in car applications but it is not so efficient to deal with modern car applications. The automotive UFS is the right solution for heavy car applications in terms of higher capacity, endurance, power efficiency, and excellent performance to cope with the challenges of modern applications. Major car developers were utilizing the eMMC for managing the data of applications but soon it replaced it with UFS due to the limitation of limited eMMC storage and read/write capacity. The eMMC provides 300Mb/s read performance while FORESEE automotive UFS 2.1 read performance can reach up to 700MB/s.

Offering Support for Fast Data Operations

FORESEE automotive UFS is offering fast read and write operations that is enabling quick task management in data-centric applications. These chips are employing the write booster technology to further enhance the data processing of heavy applications. eMMC is not as efficient in managing fast playback operations due to its half-duplex feature whereas car-grade UFS provides full-duplex read and write support.  

Fast Booting Time

The key reason that encourages the use of car-grade UFS in automotive systems is its fast booting time. This chip is made to provide faster sequential read operations that contribute to a faster boot time. Its enhanced storage can handle the massive amount of booting data. FORESEE universal flash storage products have 2x faster write and 3x faster read performance than the earlier storage solutions.

Better Data Integrity

The memory chip is responsible for maintaining data consistency and protecting the data from sudden data loss and unauthorized data access. The earlier memory solutions such as eMMC have very few measures for data integrity which make them less capable for modern car applications. Thankfully, FORESEE has adopted advanced technologies such as ECC, low-power standby mode, power-safeguard mode, refresh mode, HPB, and FBA data acceleration mode for achieving better results.

Following the High Qualification Standards

Automotive UFS is AEC-Q100 qualified which guarantees its reliable operation. The AEC-Q100 is a standard for determining the quality of automotive chips. Our chips are made by utilizing premium memory resources, Longsys’ in-house firmware, and innovative technologies. High-reliability measures are taken to deliver the best product to our customers. These measures include high workload testing, voltage testing, low and high-temperature testing, aging testing, data operations, and failure verification, mechanical stress testing, shock testing, etc. The automotive industry is embracing FORESEE car-grade UFS because of its high qualification standards and -40℃~105℃ wider temperature endurance.
