The automotive-grade LPDDR4x is Longsys’ flagship product for smart cockpits, with capacities from 2GB to 8GB, speeds of up to 4266Mbps, supporting AEC-Q100 Grade 2 standards, and operating at temperatures from -40°C to 105°C.
Its dual-channel Bank Group architecture improves bandwidth utilization by 30%, effectively reducing AI voice assistant wake-up delay for an “instant response” interactive experience. The low-power design, using 0.6V VDDQ voltage and PASR sleep mechanisms, reduces energy consumption while delivering high performance, suitable for multi-screen interaction and high computing power requirements.
Signal integrity is another highlight of LPDDR4x:
- Built-in ODT technology suppresses high-speed signal reflection noise through dynamic impedance adjustment
- DQS technology optimizes data read/write timing to ensure transmission stability in complex electromagnetic environments
These features provide reliable support for the high bandwidth requirements of smart cockpits and assisted driving, excelling particularly in AI applications such as multi-modal interaction and emotional mapping engines.
Longsys’ LPDDR4x uses self-developed ATE testing and Yuancheng Suzhou packaging, combined with high-precision wide-temperature testing technology to ensure long-term stability in extreme environments. This full-process self-control capability not only enhances product competitiveness but also provides flexibility for customized development for automotive companies.
Automotive-Grade UFS and SPI NAND Flash: Dual Drivers of High Performance and Compact Design
The automotive-grade UFS covers 2.1/3.1 protocols with capacities ranging from 64GB to 256GB, equipped with the self-developed WM7000 series controller. It delivers 6x better read/write performance than eMMC, supports LDPC algorithms, Write Booster, and HPB functions, adapting to advanced driver assistance systems and cockpit HMI systems.
The WM7000 series achieves full protocol coverage of UFS 4.1/3.1/2.2/2.1, providing an upgrade path for future “hardware embedded, software-defined” approaches.
The automotive-grade SPI NAND Flash is designed for vehicle gateways and communication modules, featuring compact WSON8 packaging (8×6mm), capacities from 1Gb to 4Gb, supporting 100,000 write cycles and 10-year data retention.
The self-developed ECC error correction engine effectively addresses bit flip errors, while the 1.8V low-power design and Quad SPI interface optimize OTA upgrade and log writing efficiency. This high-density, low-power storage solution ensures long-term stable operation of connected vehicle terminals.
The combination of UFS and SPI NAND Flash meets the diverse needs of intelligent vehicles, from high-computing domain controllers to compact gateways.
