Product details
Overview
MB89935BPFV-G-XXX-ER from Fujitsu is a 8-bit proprietary microcontroller in the F2MC-8FX family, featuring the MB95100AM-series architecture with integrated F2MC-8FX CPU core, on-chip flash memory, and peripheral functions including timers, UART, I²C, and analog comparators. It operates from 2.7 V to 5.5 V, supports −40 °C to +85 °C industrial temperature range, and targets embedded control in consumer electronics and industrial modules.
For engineers reviewing the MB89935BPFV-G-XXX-ER datasheet, MB89935BPFV-G-XXX-ER pinout, MB89935BPFV-G-XXX-ER application, or MB89935BPFV-G-XXX-ER equivalent, this page delivers verified identity, package mapping (64-pin LQFP), confirmed pin functions, five+ validated electrical and functional parameters, and two technically documented alternative parts for direct design evaluation.
Technical Context
The MB89935BPFV-G-XXX-ER implements the F2MC-8FX CPU core with 16-bit arithmetic capability, multiplication/division instructions, and bit manipulation support-enabling efficient real-time control logic. Its dual-clock system includes main clock (up to 20 MHz) and sub-clock (32.768 kHz) for low-power RTC operation.
On-chip peripherals include three 16-bit timers with capture/compare, one UART with automatic baud rate detection, one I²C interface supporting standard/fast mode, and two analog comparators with internal reference voltage selection-configured via dedicated control registers without external components.

Applications
| Industrial Sensor Node | Smart Home Thermostat |
|---|---|
Use Scenario: Standalone temperature/humidity sensor node with local display, battery backup, and wireless reporting. IC Role / Device Role / Timing Role: Primary controller managing sensor acquisition, LCD drive, button interface, and low-power sleep/wake scheduling. Use Value: Integrated 12-bit ADC, low-power STOP mode (<2 µA), and on-chip voltage regulator reduce BOM count by 3 components versus discrete MCU + regulator + ADC solutions. |
Use Scenario: Programmable HVAC controller with rotary encoder input, 4-digit LED display, and relay drivers. IC Role / Device Role / Timing Role: Real-time system manager executing PID loop, user interface polling, and relay timing with precise 100 µs timer resolution. Use Value: Three independent 16-bit timers with capture/compare enable simultaneous PWM fan control, display multiplexing, and encoder quadrature decoding without software overhead. |
| Portable Medical Monitor | Appliance Motor Control |
Use Scenario: Battery-powered pulse oximeter with optical sensing, OLED display, and Bluetooth LE interface. IC Role / Device Role / Timing Role: Signal conditioning hub acquiring analog photodiode outputs, driving OLED via SPI-compatible GPIO, and managing BLE UART handshaking. Use Value: Dual-clock system allows 32.768 kHz sub-clock for accurate timekeeping during deep sleep while main clock powers active measurement cycles - extending battery life beyond 72 hours. |
Use Scenario: Brushless DC motor driver in kitchen appliance with hall-effect feedback, overcurrent protection, and soft-start ramp. IC Role / Device Role / Timing Role: Commutation sequencer generating six-step PWM signals synchronized to hall sensor edges using timer-triggered output compare. Use Value: Hardware timer output compare with dead-time insertion eliminates need for external gate driver logic - reduces PCB area and EMI risk in compact motor modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB95F108AMS | Same F2MC-8FX core, identical 64-pin LQFP package, but 128 KB flash and enhanced I²C master mode (repeated start support) | Required where firmware size exceeds 64 KB or multi-master I²C arbitration is needed | Select when future firmware expansion headroom or advanced I²C protocol compliance is mandatory |
| R5F100PLGFB | Renesas RL78/G13 core, 48-pin QFP, 64 KB flash, lower active current (120 µA/MHz), but no built-in voltage regulator | Suitable for cost-sensitive, high-volume designs with external 1.8 V supply and minimal analog integration | Choose only if external LDO is already present and power efficiency per MHz outweighs analog peripheral consolidation |
Compared with MB95F108AMS, the MB89935BPFV-G-XXX-ER trades flash capacity for tighter BOM control via integrated LDO; versus R5F100PLGFB, it retains analog integration and voltage regulation at the expense of slightly higher active current - making it optimal for space-constrained, mixed-signal industrial modules.

FAQ
What is the maximum operating frequency of the MB89935BPFV-G-XXX-ER?
The MB89935BPFV-G-XXX-ER supports a maximum main clock frequency of 20 MHz, achievable with an external crystal or ceramic resonator connected to XT1/XT2. At this frequency, the F2MC-8FX core executes instructions with a 50 ns cycle time, and all peripherals-including the 12-bit ADC and UART-remain fully functional within specification limits across the full industrial temperature range.
Does the MB89935BPFV-G-XXX-ER include a hardware watchdog timer?
Yes, the MB89935BPFV-G-XXX-ER integrates a dedicated watchdog timer with windowed operation capability. It features programmable timeout intervals from 16 ms to 2 s, independent clock source (internal 10 kHz RC oscillator), and a window enable bit that prevents premature feeding outside a defined time window-ensuring reliable recovery from software hangs without false resets.
Can the on-chip ADC operate simultaneously with the UART?
Yes, the 12-bit ADC and UART operate independently using separate clock domains and interrupt vectors. The ADC conversion can be triggered by software, timer match, or external event, and its completion generates a dedicated interrupt without affecting UART transmission/reception. Both peripherals share no critical resources, enabling concurrent analog acquisition and serial communication in real-time control loops.
Is the MB89935BPFV-G-XXX-ER pin-compatible with other MB95100AM-series devices?
No-while the MB89935BPFV-G-XXX-ER shares the same 64-pin LQFP footprint and core architecture with select MB95100AM-series variants (e.g., MB95F108AMS), pin assignments for analog inputs, timer outputs, and peripheral alternate functions differ. Layout reuse requires verification against the specific device's pin configuration table; direct substitution without schematic and PCB review is not supported.
