MB90F543GPF-GE - 16-Bit 16MHz 128KB Flash CAN MCU | Fujitsu
MPN： MB90F543GPF-GE ✓ 啟用中MB90F543GPF-GE 概覽
A microcontroller is a programmable integrated circuit containing a processor core, nonvolatile memory, I/O ports, timers, and communication peripherals. The MB90F543GPF belongs to the proprietary F²MC-16LX family, a 16-bit embedded-control architecture positioned between simple 8-bit devices and higher-end 32-bit microcontrollers. Its combination of Flash memory, CAN control, and extensive I/O makes it suitable for compact embedded controllers that require deterministic peripheral control and field-updatable firmware.
The verified source data identifies 128 KB of Flash, a 16 MHz clock, an 81-pin I/O interface, and an operating supply range of 4.5 V to 5.5 V. The on-board FULL-CAN controller reduces the need for an external CAN transceiver in network-interface designs. Flash storage also retains firmware during power loss, allowing firmware updates and persistent configuration without external nonvolatile memory.
The 100-QFP package measures approximately 14 mm by 20 mm and has a stated height of 3.35 mm. Its fine-pitch footprint requires careful PCB layout, clean supply routing, and assembly-process control. Because a 100-pin QFP is not the smallest microcontroller package, designers gain abundant I/O and peripheral access while accepting a larger board footprint than an LQFP or QFN option.
Typical applications include automotive body and gateway controllers, industrial CAN nodes, actuator and motor-control modules, instrument-cluster electronics, and factory automation equipment. The combination of a 5 V operating range and integrated CAN is especially relevant where legacy automotive and industrial systems use 5 V logic rather than low-voltage 3.3 V rails.
Designers should preserve the specified 4.5 V to 5.5 V supply range, account for CAN bus transients through an appropriate external transceiver and protection network, and validate every pin assignment against the manufacturer datasheet. Toolchain and peripheral details not present in the supplied source data should not be inferred from the model name.
This page consolidates verified source specifications, package constraints, sourcing links, application guidance, and candid replacement analysis. Because the web results expose family and order-code variants but do not establish five unique drop-in replacements, no unsupported equivalents are presented as drop-in parts.

典型應用
MB90F543GPF-GE 適用於 6 應用s: Automotive CAN Gateway Controller, Industrial CAN Control Module, Automotive Actuator Controller, Factory Automation Sensor Node, Instrumentation and Control Panel, Legacy 5V Embedded Platform.
Automotive CAN Gateway Controller
The MB90F543GPF-GE fits an automotive CAN gateway because it combines a 16 MHz F²MC-16LX core, 128 KB Flash memory, 81 I/O ports, and an integrated FULL-CAN controller. Firmware can reside in on-chip Flash, while the I/O count supports status inputs, sensors, and actuator signaling around the network node. The 4.5 V to 5.5 V range aligns with 5 V-class vehicle electronics. Before production use, confirm the exact GE suffix's automotive grade and qualification, then place an appropriate CAN transceiver and transient protection between the controller and the physical bus.
推薦
Industrial CAN Control Module
The MB90F543GPF-GE is suitable for industrial CAN nodes that combine protocol handling with substantial discrete I/O. Its FULL-CAN peripheral supports communication tasks, while 81 I/O lines can connect discrete sensors, status indicators, relays, and machine controls without requiring a larger bus-switching matrix. The 16 MHz clock supports time-based control and service routines, and 128 KB Flash provides room for application firmware and parameter data. Designers should validate timing against the datasheet and isolate the bus with a qualified transceiver and protection network.
推薦
Automotive Actuator Controller
The MB90F543GPF-GE can coordinate solenoids, relays, position sensors, and diagnostic messaging where an automotive-grade interface and deterministic control are priorities. Its 81 I/O ports provide ample signal access for sensing and switching, while Flash retains control code and configuration through power cycles. The 4.5 V to 5.5 V supply range supports 5 V-based control electronics. The exact GE suffix grade, pin multiplexing, drive-current limits, and automotive qualification must be verified before using it in a safety-relevant actuator path.
推薦
Factory Automation Sensor Node
The MB90F543GPF-GE supports factory sensor nodes that need many inputs, local logic, and network connectivity without an external protocol controller. Use its 81 I/O ports for digital sensors, limit switches, and machine-state inputs, and use the FULL-CAN controller to publish measurements or receive commands. Its 16 MHz F²MC-16LX core and 128 KB Flash provide a compact embedded-control platform. Industrial deployments should include regulated 5 V supply filtering, CAN-bus isolation or protection appropriate to the installation, and watchdog and fault-handling support verified from the datasheet.
推薦
Instrumentation and Control Panel
The MB90F543GPF-GE can serve as the embedded controller in an industrial or automotive instrument panel where numerous discrete signals and a CAN backbone must be coordinated. The 81 I/O ports are useful for keys, indicators, relay drives, and sensor interfaces, while 128 KB Flash accommodates panel firmware and calibration tables. Its 5 V-class operating range supports equipment designed around legacy logic levels. Layout must account for the 100-QFP footprint and approximately 3.35 mm package height, and all display or actuator outputs must be checked against individual pin current ratings.
推薦
Legacy 5V Embedded Platform
The MB90F543GPF-GE is relevant when maintaining a proprietary 5 V embedded-control platform with existing F²MC software and CAN infrastructure. Its 4.5 V to 5.5 V range avoids forcing a three-level supply redesign, while Flash permits field-retained firmware. The large I/O count simplifies consolidation of discrete control functions. Because the device occupies a 100-QFP footprint and belongs to a specialized family, lifecycle and obsolescence monitoring, authorized sourcing, and careful hardware revision control are essential; a generic MCU may require more board redesign or software migration.

主要差異化特點
- High verified I/O count for a 16-bit Flash MCU (對比MB90F543GPF-GE1)
- Integrated FULL-CAN architecture (對比CY90F543GPF-GE1)
- Flash-retained firmware in a 5 V-class platform (對比MB90F543GPFR-GE1)
設計說明
The verified operating range is 4.5 V to 5.5 V, so the power rail must remain inside that window over temperature, tolerance, ripple, and transient conditions. Place local high-frequency bypass capacitance close to the MCU supply pins and provide bulk capacitance near the regulator output. Exact pin names, capacitor values, and decoupling requirements must be taken from the manufacturer datasheet rather than inferred from another member of the F²MC family.
Treat the 100-QFP as a fine-pitch assembly constraint. Follow the manufacturer land pattern and pin-1 orientation, reserve adequate solder-paste and assembly allowances, and avoid placing tall components where they can interfere with tooling. The known package is approximately 14 mm by 20 mm and 3.35 mm high, but the verified source set does not include a pin table, so no signal-level routing should be finalized until it is checked against the datasheet.
Do not substitute GE, GE1, or GPFR-GE order codes based only on their visual similarity. Verify package dimensions, pin names, temperature grade, qualification, memory organization, electrical limits, and lifecycle status. The supplied search results reference these related parts but do not establish full equivalence; use an authorized manufacturer migration document or perform board-, firmware-, and system-level validation before substitution.
For a CAN implementation, the MCU's FULL-CAN controller is not a complete physical bus interface. Use an appropriate CAN transceiver, logic-level matching, common-mode strategy, termination, and transient protection recommended for the installation. Validate radiated and conducted emissions under worst-case bus faults. Do not assume the controller's bus timing is interchangeable among related order codes without checking the datasheet and firmware configuration.
合規資訊
The supplied sources identify automotive and industrial use but do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals compliance.
