Selection and cost evaluation of automotive electronic components

In the process of selecting automotive electronic components, factors that need to be considered include the device's temperature resistance level, Flash size, requirements for supporting Autosar, ETH, CAN, LIN, EEPROM requirements, main frequency requirements, etc., all of which will affect the cost of the MCU. In addition, it is also necessary to consider the customer's requirements for EMC test levels, as well as the device's quiescent current, noise, EN/PG, RESET and other functional requirements.
