Fudan Microelectronics' EEPROM Helps In-vehicle Cameras Achieve Intelligent Upgrades

With the development of automotive intelligence and connectivity, in-vehicle cameras, as the core sensing devices of ADAS (Advanced Driver Assistance Systems) and autonomous driving, have witnessed an explosive growth in market demand. In the hardware selection scheme, the collaborative design of the main control chip, image sensor, and storage device has become crucial. Thanks to its extremely high reliability, ultra-low power consumption, and highly flexible data storage capabilities, EEPROM (Electrically Erasable Programmable Read-Only Memory) is increasingly regarded as the best choice in the storage solutions for in-vehicle cameras. Compared with traditional memories, EEPROM has a write-erase lifespan of millions of times, can operate stably in extreme temperatures ranging from -40°C to 125°C, meets the requirements of the automotive-grade AEC-Q100 certification, and is particularly suitable for scenarios such as camera parameter calibration, firmware upgrades, and accident data recording.

In the in-vehicle camera system, EEPROM plays a core role as a "data manager." On the one hand, it stores the camera's initialization parameters (such as lens distortion correction coefficients, white balance configurations, etc.) to ensure that the device can quickly enter the working state after startup. On the other hand, by recording key events in real time (such as video frame data at the moment of a collision), it provides a reliable basis for accident tracing. The low-power design of EEPROM is very ingenious, effectively improving the battery life of in-vehicle cameras. Its non-volatile feature is even more crucial, enabling data to be completely preserved without loss in the event of a power outage. In terms of functional safety, EEPROM supports the data verification and error correction (ECC) mechanism, further enhancing the integrity and security of the stored data.

The automotive-grade EEPROM, FM25N256AI3-DN-T-G, launched by Fudan Microelectronics, is specifically tailored for in-vehicle camera applications. This product uses an industrial-grade SPI interface, supports a storage capacity of 256Kbit, and has a read-write speed of up to 5MHz, meeting the real-time storage requirements of high-frame-rate video streams. This chip, which has passed the AEC-Q100 Grade 1 certification, has an operating voltage range of 1.8V to 3.6V and can work in tandem with various mainstream automotive power supply systems. Moreover, it can operate stably regardless of the low temperature of -40°C or the high temperature of 125°C. In addition, the FM25N256AI3-DN-T-G has a hardware write protection function to prevent accidental data overwriting, and it also supports the page write mode, improving the efficiency of batch data writing. As the official agent of Fudan Microelectronics, Mandu Technology provides one-stop services ranging from selection consultation, technical training to sample testing, helping customers quickly implement product landing.

With the trend of in-vehicle cameras evolving towards high resolution and multi-functionality, Fudan Microelectronics' EEPROM, with its superior performance and reliability, has become an ideal choice for R&D engineers. Whether it is parameter calibration, firmware upgrades, or data recording, the FM25N256AI3-DN-T-G can provide stable support, helping in-vehicle cameras achieve more efficient and safer intelligent upgrades. As a core partner of Fudan Microelectronics, Mandu Technology will continue to empower customer innovation with professional services and jointly promote the high-quality development of the intelligent automotive industry.
