■ DESCRIPTION

The MB90340E series with up to 2 FULL-CAN* interfaces is especially designed for automotive and other industrial applications. Its main feature are the 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 power to the MCU core (3 V) is supplied by a built-in regulator circuit, giving these microcontrollers superior performance in terms of power consumption and tolerance to EMI.
