MB90438L (S) General Description
The MB90435 series with FLASH ROM is specially designed for industrial applications.
The instruction set by F2MC-16LX CPU core inherits an AT architecture of the F2MC* family with additional instruction sets for high-level languages, extended addressing mode, enhanced multiplication/division instruc-tions, and enhanced bit manipulation instructions.The micro controller has a 32-bit accumulator for processing long word data.
The MB90435 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) ) .
* : F2MC stands for FUJITSU Flexible Microcontroller.
MB90438L (S) Maximum Ratings
*1 : AVCC, AVRH, AVRL should not exceed VCC. Also, AVRH, AVRL should not exceed AVCC, and AVRL does not exceed AVRH.
*2 : 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 supercedes the VI 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, P60 to P67,
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.
• 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.
