Application Scenarios & Design Considerations

16-bit Proprietary Microcontroller

Alternative Part Number

  • MB90F347A --: Same Fujitsu F2MC-16LX family, higher flash density, largely pin/function compatible and a common drop-in upgrade for MB90F334A designs.
  • MB90F337A --: Closely related F2MC-16LX variant with similar peripheral set and memory size, suitable when the exact MB90F334A is unavailable.
  • MB90F345A --: Another F2MC-16LX family member with comparable core and peripherals, usable as a functional substitute with minor firmware adaptation.
  • MB90334A --: Same F2MC-16LX family 16-bit microcontroller with comparable flash and peripheral set; Fujitsu (now Cypress/Infineon) is the original silicon source behind the Fuji-branded part, so pin and code compatibility is high.
  • MB90335A --: Closely related F2MC-16LX device with similar core, memory size and I/O; often used as a drop-in substitute when the exact MB90F334A variant is unavailable.
  • MB90333A --: Another member of the same F2MC-16LX series with matching architecture and package options; a practical fallback requiring only minor firmware adaptation.
  • MB90F387S --: F2MC-16LX series MCU with similar architecture and peripheral set, suitable as a functional substitute where pinout is adapted.
  • MB90349A --: Related F2MC-16LX device with comparable CPU core and I/O features, usable as an alternative after verifying memory and pin compatibility.
