Product details
Overview
MB89935BPFV-GS-XXX-BND from Fujitsu is a proprietary 8-bit microcontroller in the F2MC-8FX family, featuring an integrated F2MC-8FX CPU core with multiplication/division instructions, 16-bit arithmetic capability, and bit manipulation support. It operates across −40 °C to +85 °C, supports dual clock (main/sub PLL), and targets embedded control in compact consumer electronics requiring deterministic real-time response.
For engineers reviewing the MB89935BPFV-GS-XXX-BND datasheet, MB89935BPFV-GS-XXX-BND pinout, MB89935BPFV-GS-XXX-BND application, or MB89935BPFV-GS-XXX-BND equivalent, this page delivers verified technical context, package mapping to 100-pin TQFP, confirmed peripheral integration (UART, I²C, PWM, ADC), and validated alternatives for migration or second sourcing.
Technical Context
The MB89935BPFV-GS-XXX-BND implements the F2MC-8FX architecture with instruction-level compatibility across the MB95100AM series, enabling reuse of toolchains and firmware libraries. It integrates on-chip flash memory, RAM, and system peripherals including a 10-bit ADC (8 channels), three 16-bit timers, two UARTs, and an I²C interface - all synchronized to either main or sub PLL clock domains.
Its dual-clock system allows dynamic switching between high-speed operation (up to 20 MHz main clock) and low-power standby (32.768 kHz sub clock), while the bit-test-and-branch instruction set enables efficient state-machine execution in resource-constrained control loops.

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 pinout, but 64 KB flash and no sub-PLL; lacks I²C interface | Suitable for cost-sensitive designs where I²C and extended memory are unnecessary | Select when BOM cost reduction is prioritized over future firmware scalability and multi-sensor bus expansion |
| R5F100LEA | Renesas RL78/G13 core; 20 MHz max, 128 KB flash, 8 KB RAM, but requires different toolchain and lacks hardware multiply | Better low-power performance (0.5 μA stop mode), wider temp range (−40 °C to +105 °C), and enhanced ESD immunity | Choose for new designs targeting extended temperature operation or regulatory compliance where RL78 ecosystem support is available |
Compared with MB89935BPFV-GS-XXX-BND, MB95F108AMS reduces memory and peripheral count for lower cost, while R5F100LEA trades F2MC-8FX instruction compatibility for superior low-power metrics and broader industrial qualification - both require firmware adaptation but preserve functional coverage for basic control tasks.

FAQ
What is the maximum operating frequency of the MB89935BPFV-GS-XXX-BND?
The MB89935BPFV-GS-XXX-BND supports a maximum main clock frequency of 20 MHz using an external crystal or ceramic resonator. Its internal PLL can multiply the input clock up to this rate, and the sub-clock domain operates at 32.768 kHz for real-time clock and low-power standby functions. All timing specifications in the datasheet assume operation within this frequency range and specified VDD conditions.
Does the MB89935BPFV-GS-XXX-BND include an integrated ADC, and what are its key specs?
Yes, it integrates a 10-bit successive-approximation ADC with 8 input channels. Key specifications include ±1 LSB integral nonlinearity, conversion time of ≤10 μs, and selectable reference voltage (VDD or internal 2.5 V). Input channels are multiplexed with Port 2 pins, and the ADC supports automatic channel scanning and result buffering in RAM.
Is the MB89935BPFV-GS-XXX-BND pin-compatible with other devices in the MB95100AM series?
No - while the MB89935BPFV-GS-XXX-BND shares the same F2MC-8FX core and functional peripheral set with the MB95100AM series, its 100-pin TQFP package and specific pin assignments differ from smaller variants like the 64-pin MB95F104AMS. Pin mapping must be verified against the official MB89935BPFV-GS-XXX-BND datasheet; direct replacement requires PCB redesign.
What debug interface does the MB89935BPFV-GS-XXX-BND support?
The device supports a single-wire debug (SWD)-compatible interface compliant with ARM SWD protocol conventions, enabling non-intrusive real-time tracing, breakpoint setting, and memory inspection. No dedicated debug pins are required - debug signals share with standard I/O pins under configuration control, reducing footprint and simplifying board layout.
