There are available candidates listed on the left side block of the diagram above, but I am here to ask for advice if there is any automotive quality Cypress MCU part suggestion adequate for the job.
The MCU part, that we seek, shall -have the automotive quality. - be used for the step motor starter application for "active grille shutters" (which help the vehicle's aerodynamic design). - be used along with the LIN step motor gate driver from Infineon (see the blocks above). - support LIN+SPI communication protocol ( MCU LIN works in Slave mode. target MCU will work as LIN slave ) - have an equal or smaller packaging size with the products listed above preferably due to PCB size. (S9S08SL8F1MTJ (TSSOP-20) / ATSAMHA1E15A-B(32-pin QFN) ) - have a relatively good delivery date in terms of logistics.
If you could suggest us the Cypress automotive part that fits the MCU part of the block, that would be really appreciated. Thank you in advance.
