MB91460T Series
FR60 32-bit Microcontroller
MB91460T series is a line of general-purpose 32-bit RISC microcontrollers designed for embedded control applications which require
high-speed real-time processing, such as consumer devices and on-board vehicle systems. This series uses the FR60 CPU, which
is compatible with the FR family of CPUs.
This series contains the LIN-USART and CAN controllers.
