Infineon/CYPRESS CY91F579CMPMC-GSE2

This series is Cypress 32-bit microcontroller designed for automotive and industrial control applications. It contains the FR81S CPU that is compatible with the FR family. The FR81S has a high level performance among the Cypress FR family by enhancing CPU instruction pipeline and load store processing, and improving internal bus transfer. It is best suited for application control for automotive.
