Winbond's storage solutions empower OBD intelligent automotive applications.

Amidst the wave of automotive intelligence and connectivity, the OBD (On-Board Diagnostics) intelligent terminal, as the core carrier for vehicle data interaction, collects real-time operational data from components such as the engine, sensors, and transmission. It enables functions like fault diagnosis, fuel consumption analysis, driving behavior recording, and remote data upload, thus becoming a key underlying hardware in the connected vehicle ecosystem. The hardware design of these terminals must balance data processing efficiency, storage stability, and adaptability to complex environments. Their mainstream architecture typically includes a high-performance main controller chip, various sensor modules, wireless communication units, and a storage system.

In the selection of storage solutions, NAND FLASH stands out due to its superior overall performance. Compared with traditional NOR FLASH or EEPROM, its parallel data transfer mechanism meets the high-speed writing needs of frequent sensor data. The GB-level large-capacity storage supported by a single chip can effectively accommodate long-term operation logs and temporary data buffering. Moreover, its low-voltage operation mode and dynamic power consumption optimization design better meet the stringent requirements of automotive devices for battery endurance. Especially in harsh environments such as high temperatures (-40°C to 85°C), vibration, and voltage fluctuations, the industrial-grade durability and data protection mechanisms of NAND FLASH provide a solid guarantee for the stable operation of terminals, making it the preferred storage medium for current OBD hardware solutions.

NAND FLASH plays the key role of a data "nerve center" in OBD intelligent terminals. Its high-speed read and write characteristics (with read speeds reaching hundreds of MB/s) support the terminal's real-time processing of high-frequency data such as engine fault codes and sensor status, avoiding system response delays caused by storage latency. The large-capacity storage space can meet the device's needs for caching massive amounts of data offline and quickly synchronizing it to the cloud when connected to the network, improving data interaction efficiency. In response to the particularities of the automotive environment, the built-in error correction code (ECC) technology of NAND FLASH can detect and correct transmission errors in real time. Combined with hardware-level power failure protection mechanisms, it effectively deals with voltage surges during vehicle startup, ensuring the integrity of fault diagnosis data. In addition, its compact packaging design and high storage density provide hardware support for the miniaturization layout of OBD terminals, helping devices achieve functional integration within limited space.

Winbond's W29N04GVBJAA NAND FLASH, optimized specifically for OBD intelligent terminals, offers significant technological advantages and application value. The application of the Toggle DDR 2.0 interface gives this product high-speed performance with 400MB/s read and 130MB/s write capabilities, enabling efficient storage and retrieval of real-time data. The 4GB capacity configuration balances performance and cost, making it suitable for mainstream OBD terminals' log storage, firmware upgrades, and temporary data buffering needs. Based on reliability design, the product has over 3000 program/erase cycles. Combined with intelligent power consumption control technology, it can automatically adjust voltage and frequency according to device load, reducing idle power consumption while effectively extending battery life. As a core technical configuration, the application of LDPC error correction algorithm significantly enhances the product's anti-interference capability under harsh working conditions, establishing a reliable defense for the accuracy of long-term data storage.
