【Abstract】The key core electronic components of off-road special vehicles need to achieve autonomous control，which can meet the requirements of localization and also meet some special low-temperature environment usage requirements. The article analyzes and experimentally verifies the issue of IO port out of control when the domestic MCU of a certain special vehicle body controller is powered on，providing some reference for solving the instability problem of the body controller function.

【Key words】off road special vehicles；domestic MCU；IO port out of control；low temperature

1  背景

隨著芯片慌的出現(xiàn)，汽車核心芯片的供貨及產(chǎn)品數(shù)據(jù)安全等風險系數(shù)急劇加大，如何保障產(chǎn)品自主可控是國內(nèi)廠商急需面對的問題。（剩余3818字）
