*1: This parameter is based on VSS = AVSS = 0 V
*2: Set AVCC and VCC to the same voltage. Make sure that AVCC does not exceed VCC and that the voltage at the analog inputs does not exceed AVCC when the power is switched on.
*3: VI and VO should not exceed VCC + 0.3 V. VI should not exceed the specified ratings. However if the maximum current to/from an input is limited by some means with external components, the ICLAMP rating supersedes the VI
rating.
*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,P70 to P77, P80 to P87, P90 to P97, PA0, PA1
*5: • Applicable to pins: P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47,P50 to P57 (Evaluation device : P50 to P55) , P60 to P67, P70 to P77, P80 to P87,P90 to P97, PA0 to PA1
• Use within recommended operating conditions.
• Use with DC voltage (current)
• The +B signal should always be applied by using 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 the rated value, 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.
• Sample recommended circuits:
• Input/output equivalent circuits
WARNING: Semiconductor devices can be permanently damaged by application of stress(voltage,current,temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
DescriptionThe MB90340E-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 m CMOS technology, Fujitsu now offers on-chip Flash ROM program memory up to 512 Kbytes.
The power to the MCU core (3V) is supplied by a built-in regulator circuit, giving these MB90340E superior performance in terms of power consumption and tolerance to EMI.
