The MB90340-series with up to 2 FULL-CAN* interfaces and FLASH ROM 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. With the new 0.35 µm CMOS technology, Fujitsu now offers on-chip FLASH-ROM
program memory up to 512 Kbytes.
The power supply (3 V) is supplied to the internal MCU core from an internal regulator circuit. This creates a
major advantage in terms of EMI and power consumption.
The internal PLL clock frequency multiplier provides an internal 42 ns instruction cycle time from an external
4 MHz clock.
The unit features an 8 channel Output Compare Unit and 8 channel Input Capture Unit with 2 separate 16-bit free
running timers. 4 UARTs constitute additional functionality for communication purposes.
