Application Scenarios & Design Considerations

16-bit Proprietary Microcontroller

Alternative Part Number

  • MB90F546 --: Same F2MC-16LX family with larger flash and compatible peripherals; often used as a drop-in upgrade when memory size is not critical.
  • MB90F548 --: Closely related F2MC-16LX device with similar core, package options, and peripheral set; suitable substitute with minor firmware adjustment.
  • MB90F387 --: F2MC-16LX series MCU with comparable feature set and pinout options; viable alternative when the exact MB90F543 is unavailable.
  • MB90F543G --: Same MB90F543 series MCU from Fujitsu (original manufacturer) with equivalent F2MC-16LX core and pinout; widely available and closest functional match.
  • MB90F547 --: Sister device in the same F2MC-16LX family with similar flash, RAM and peripheral set; often used as a drop-in substitute when the exact variant is unavailable.
  • MB90F553A --: Another F2MC-16LX family MCU with comparable features and package options; suitable alternative when supply of the MB90F543 is constrained.
