On March 14, at the Embedded World 2023 International Embedded System Exhibition MeiG Intelligent, the world's leading provider of wireless communication modules and solutions, launched a new generation of 5G automotive grade C-V2X MA925 series modules . This series of modules is designed, developed and produced based on the second-generation Snapdragon® automotive 5G modem and RF platform recently launched by Qualcomm Technologies . The platform supports the 3GPP Release 16 standard, integrates multi-core CPU processors, and has a maximum computing power of 22K DMIPS; at the same time, major adjustments and optimizations have been made on the software architecture, and the Hypervisor mechanism has been introduced to greatly improve product security and ease of use. and maintainability.
In terms of communication capabilities, MeiG Smart’s new generation of 5G vehicle-grade MA925 series modules support the 3GPP 5G R16 standard, support 5G NR independent networking (SA) and non-independent networking (NSA) modes, and are backward compatible with 4G/3G /2G network, can support up to 4.4Gbps downlink rate, and is compatible with the frequency band requirements of mainstream countries and regions around the world.
Secondly, MA925 series modules support the optional C-V2X function, use the globally unified ITS 5.9GHz frequency band to deploy V2X applications, and can use PC5 Mode4 mode for direct connection communication. This series of modules reserves SDIO interface for external 802.11p unit (DSRC), and integrates a CPU processor with 22K DMIPS computing power inside. The development of V2X applications no longer requires a separate external application processor, which has a great cost Optimize and improve. Through the built-in ECDSA hardware engine, the C-V2X signature verification performance of up to 6000 times per second can be achieved.
In terms of positioning, MA925 series modules can also provide flexible GNSS positioning services, support L1+L5 / L1+L2 (optional) dual-frequency GNSS, inertial navigation (DR), GNSS data post-processing engine (PPE) and data correction Services and other technologies help vehicles achieve fast, accurate and reliable positioning in various environments.
此外，该系列模组拥有丰富的接口，如PCIe 3.0、USB 2.0 & 3.1、SDIO、I2S、SPI、I2C、UART、PCM、ADC、(U)SIM、GPIO等，方便与其他车载单元进行交互，适应各种车载应用场景。
在算力方面，全新一代5G车规级模组MA925系列具备强大的运算能力，综合算力高达22K DMIPS，可满足更多的算力需求，在不增加MCU的前提下为汽车智能化应用的开发提供了算力基础，创造出更大的想象和应用空间，满足汽车智能化体验需求。
除了性能优异外，MA925系列模组内部芯片符合AEC-Q100标准，严格按照IATF16949:2016汽车行业质量管理体系标准研发和制造，可经受严苛的汽车应用环境考验，并保持稳定高效的通信性能。
未来，美格智能将持续加大在智能网联汽车领域的研发投入，尤其是5G车规级模组与车载T-BOX等行业解决方案的投入力度，加速合作伙伴产品的上市步伐，提高汽车网联化、智能化水平，让出行更安全、更智能、更高效。
