MB90F394H

Product Summary

The MB90F394H is a 16-bit Proprietary Microcontroller. It is especially designed for automotive and industrial applications. The main features of the MB90F394H are up to five on board CAN Interfaces, which conform to V2.0 Part A and Part B, while supporting a very flexible message buffer scheme and so offering more functions than a normal full CAN approach. The MB90F394H features 6 Stepper Motor Controllers with slew rate controlled high current outputs.
