*1 : AV_CC, AVRH, AVRL should not exceed V_CC. Also, AVRH, AVRL should not exceed AV_CC, and AVRL does not exceed AVRH.
*2 : V_I and V_O should not exceed V_CC + 0.3 V. V_I should not exceed the specified ratings. However if the maximum current to/from an input is limited by some means with external components, the I_CLAMP rating supercedes the V_I rating.
*3 : The maximum output current is a peak value for a corresponding pin.
*4 : Average output current is an average current value observed for a 100 ms period for a corresponding pin.
*5 : Total average current is an average current value observed for a 100 ms period for all corresponding pins.
*6 : ` Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50 to P57, P70 to P77, P80 to P87, P90 to P97, PA0
` 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 current 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 result.

The MB90540/545 series with FULL-CAN^*1 and FLASH ROM is specially designed for automotive and industrial applications. Its main features are two on board CAN Interfaces (one for MB90V545 series) , which conform to V2.0 Part A and Part B, supporting very flexible message buffer scheme and so offering more functions than a normal full CAN approach. The instruction set by F2MC-16LX CPU core inherits an AT architecture of the F2MC^*2 family with additional instruction sets for high-level languages, extended addressing mode, enhanced multiplication/ division instructions, and enhanced bit manipulation instructions.The micro controller has a 32-bit accumulator for processing long word data.The MB90540/545 series has peripheral resources of 8/10-bit A/D converters, UART (SCI) , extended I/O serial interfaces, 8/16-bit timer, I/O timer (input capture (ICU) , output compare (OCU) ) .
