General Description
MB90925 General Description
MB90925 series is a 16-bit general-purpose high-capacity microcontroller designed for vehicle meter control applications etc.
The instruction set retains the same AT architecture as F2MC-8L and F2MC-16L series, with further refinements including high-level language instructions, expanded addressing mode, enhanced signed multiplication and division computation and bit processing.
In addition, a 32-bit accumulator is built in to enable long word processing.
Note : F2MC is the abbreviation of FUJITSU Flexible Microcontroller.

*1 : The parameter is based on VSS = AVSS = DVSS = 0.0 V.
*2 : AVCC, AVRH and DVCC shall never exceed VCC.Also, AVRH shall never exceed AVCC.
*3 : The maximum current to/from and input are limited by some means with external components, the ICLAMP rating
supersedes the VI rating.
*4 : Maximum output current is defined as the peak value of the current of any one of the corresponding pins.
*5 : Average output current is defined as the value of the average current flowing over 100 ms at any one of the corresponding pins. The "average value" can be calculated from the formula of "operating current" times "operating factor".
*6 : Average total output current is defined as the value of the average current flowing over 100 ms at all of the corresponding pins. The "average value" can be calculated from the formula of "operating current" times " operating factor".
*7 : • Applicable to pins : P10 to P15, P50 to P57, P70 to P77, P80 to P87
• Use within recommended operating conditions.
• Use at DC voltage (current) .
• The +B signal should always be applied with 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 power 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 (LCD drive pins, comparator input pins, etc.) cannot accept +B signal input.
