s DESCRIPTION
The MB90340-series with up to 2 FULL-CAN* interfaces and FLASH ROM is especially designed for automotive
and 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. An internal voltage booster removes the necessity for a second programming voltage.
An on board voltage regulator provides 3 V to the internal MCU core. 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.
