DESCRIPTION
The MB90390-series with up to five FULL-CAN* interfaces and Flash ROM is especially designed for automotive
and industrial applications. Its main feature 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. With the new 0.35
μ
m 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 6 Stepper Motor Controllers with slew rate controlled high current outputs.
Furthermore it features an 8-channel Output Compare Unit and a 6-channel Input Capture Unit with two separate
16-bit free running timers. Up to 4 UARTs constitute additional functionality for communication purposes.
