製品の概要
MeiG MA922 series are based on Qualcomm’s latest second-generation Snapdragon® automotive 5G modem and RF platform, which support 3GPP Release 16 standard, 5G NR SA and NSA while compatible with 4G/3G/2G network and frequency band from mainstream countries worldwide. It integrates multi-core CPU with a maximum computing power of 20K DMIPS. The module support optional C-V2X functions using ITS 5.9GHz frequency band, capable of direct communication via PC5 Mode4. In addition, it also has GNSS service, which can support L1+L5, QDR, PPE and data fixes, and owns rich interfaces such as PCIe 3.0, USB 2.0 & 3.1, SDIO, I2S, SPI, I2C, UART, PCM, ADC, (U)SIM, RGMII/SGMII, ADC, GPIO.
MA922 series modules can provide safe and reliable auto solutions, which can be widely used in TBOX, TCU, C-V2X, OBU, RSU and other automotive related products.
The internal chip of MA922 complies with AEC-Q100 standards and are developed and manufactured in strict accordance with IATF16949:2016 automotive industry quality management system standards, and have an ultra-wide work temperature range, which can withstand the test of harsh automotive application environment and maintain stable and efficient communication performance.
