Application Scenarios & Design Considerations

16-Bit Proprietary Microcontroller

Alternative Part Number

  • MB90F462A --: Same Fujitsu F2MC-16LX family 16-bit microcontroller with comparable flash and peripherals, widely used as a drop-in substitute in legacy designs.
  • MB90F543 --: Fujitsu F2MC-16LX series MCU offering similar core speed and flash size, suitable when the exact F474 variant is unavailable.
  • MB90F387S --: Another F2MC-16LX family device with comparable on-chip flash and I/O, usable as a functional replacement with minor firmware adaptation.
