*1 : The parameter is based on V_SS = AV_SS = DV_SS = 0.0 V.
*2 : Set AV_CC and V_CC to the same voltage. Make sure that AVCC does not exceed V_CC and that the voltage at the analog inputs does not exceed AV_CC when the power is switched on.
*3 : V_I and V_O should not exceed V_CC + 0.3 V. VI should not exceed the specified ratings. However if the maximum current to/from a input is limited by some means with external components, the ICLAMP rating supersedes the VI rating. For ports P70 to P77, P80 to P87 and PA0 to PA7, VI and VO should not exceed DVCC + 0.3 V.
*4 : Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50 to P57, P60 to P67,P90 to P97, PB0 to PB7
*5 : Applicable to pins : P70 to P77, P80 to P87, PA0 to PA7
*6 : • Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50 to P57, P60 to P67 P70 to P77, P80 to P87, P90 to P97, PA0 to PA7, PB0 to PB7
• Use within recommended operating conditions.
• Use at DC voltage (current)
• The +B signal should always be applied a limiting resistance placed between the +B signal and the microcontroller.
• The value of the limiting resistance should be set so that when the +B signal is applied the input current to the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods.
• Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input potential may pass through the protective diode and increase the potential at the VCC pin, and this may affect other devices.
• Note that if a +B signal is input when the microcontroller power supply is off (not fixed at 0 V) , the power supply is provided from the pins, so that incomplete operation may result.
• Note that if the +B input is applied during power-on, the power supply is provided from the pins and the resulting supply voltage may not be sufficient to operate the power-on reset.
• Care must be taken not to leave the +B input pin open.
• Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input pins, etc.) cannot accept +B signal input.

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 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.

MB90390 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.
