Application Scenarios & Design Considerations

32-bit Proprietary Microcontrollers

Alternative Part Number

  • MBR1545 --: Schottky barrier rectifier with similar 15A current rating and low forward voltage, suitable replacement for MB91154 in power rectification.
  • MBR20100 --: Higher current Schottky diode with 20A rating and 100V reverse voltage, provides margin and is widely available as a drop-in style alternative.
  • MBR1045 --: 10A Schottky rectifier with comparable characteristics, good fit when lower current is acceptable and offers a different series naming.
  • MB90F154 --: Same MB90F154 16-bit microcontroller family with identical core and peripheral set, differing only in flash memory option, making it a direct functional substitute.
  • MB90F157 --: Closely related Fujitsu 16-bit MCU in the same F2MC-16LX family with compatible pinout and peripherals, suitable as a drop-in replacement in most designs.
  • MB90F158 --: Another F2MC-16LX family member with similar architecture and I/O, offering a viable alternative when the exact MB91154 variant is unavailable.
  • STK672-440A --: Similar motor driver IC in a comparable package with equivalent drive capability, widely available and often used as a drop-in replacement for Fuji driver devices.
  • TB6560AHQ --: Bipolar stepper motor driver with comparable voltage and current ratings, commonly substituted for Fuji MB-series driver ICs in similar applications.
  • L298N --: Dual H-bridge driver offering similar drive functionality and ratings, a well-known generic alternative when exact Fuji equivalents are unavailable.
