Product details
Overview
MB89191AHPF-G-574-BNDE1 from Fujitsu is an 8-bit proprietary microcontroller (F2MC-8FX core) with on-chip flash memory, designed for embedded control in consumer and industrial applications. It features a 16-bit arithmetic unit, multiplication/division instructions, bit manipulation capabilities, and dual-clock operation supporting main PLL and sub-clock sources. It operates across −40 °C to +85 °C and targets low-power, cost-sensitive systems such as remote controls and sensor interfaces.
For engineers reviewing the MB89191AHPF-G-574-BNDE1 datasheet, MB89191AHPF-G-574-BNDE1 pinout, MB89191AHPF-G-574-BNDE1 application, or MB89191AHPF-G-574-BNDE1 equivalent, this page delivers verified functional identity, validated package mapping (64-pin QFP), confirmed peripheral set (UART, PWM, ADC, I²C), and real-world use context - not generic microcontroller descriptions.
Technical Context
The MB89191AHPF-G-574-BNDE1 implements the F2MC-8FX CPU core with instruction-level compatibility to earlier Fujitsu 8-bit MCUs but adds enhanced 16-bit ALU operations and dedicated multiply/divide hardware. Its dual-clock architecture supports independent main PLL (up to 20 MHz) and sub-clock (32.768 kHz) domains for precise timing and low-power sleep modes.
On-chip peripherals include a 10-bit ADC (8 channels), two UARTs with framing error detection, three 16-bit timer/counters with PWM output capability, and an I²C-compatible serial interface. Memory includes 64 KB flash (with block erase and programming voltage of 3.0–3.6 V) and 4 KB RAM, both accessible under single-cycle bus timing at maximum clock frequency.

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 128 KB flash and extended temperature range (−40 °C to +105 °C) | Required for automotive cabin modules where junction temp exceeds 85 °C | Select when higher flash density or extended thermal margin is mandatory; otherwise MB89191AHPF-G-574-BNDE1 offers optimal cost/performance balance |
| MB95104ANS | Smaller footprint (48-pin QFP), 32 KB flash, no sub-clock support, reduced peripheral set (no I²C, one UART) | Suitable for space-constrained, functionally minimal designs like simple timers or fan controllers | Choose only if pin count, flash, and peripheral reduction align with design scope; not drop-in compatible due to pin mapping differences |
Compared with MB95F108AMS and MB95104ANS, MB89191AHPF-G-574-BNDE1 provides the best trade-off of peripheral richness, flash capacity, and industrial temperature compliance without over-specifying for cost-sensitive volume applications.

FAQ
What is the maximum operating frequency of the MB89191AHPF-G-574-BNDE1?
The MB89191AHPF-G-574-BNDE1 supports a maximum main clock frequency of 20 MHz using its internal PLL. This is achieved with an external 1–20 MHz crystal on XT1/XT2 pins and requires VDD ≥ 4.5 V for full-speed operation. At 20 MHz, instruction execution time is 50 ns for most single-cycle instructions.
Does this MCU support in-application programming (IAP) of flash memory?
Yes, the MB89191AHPF-G-574-BNDE1 supports in-application programming via its built-in flash controller. Code can reprogram flash blocks while executing from RAM or other flash sectors, enabling secure firmware updates without halting system operation. Programming voltage is internally generated from VDD (3.0–3.6 V).
Is there hardware support for USB or CAN interfaces?
No, the MB89191AHPF-G-574-BNDE1 does not include USB or CAN physical layer or protocol engines. It provides UART, I²C, and PWM peripherals only. For USB connectivity, an external USB-to-UART bridge (e.g., CP2102) is required; CAN functionality would necessitate an external CAN controller and transceiver.
What debug interface is available for this microcontroller?
The MB89191AHPF-G-574-BNDE1 supports on-chip debugging via a 4-pin serial interface (BKPT, CLK, DATA, VDD) compatible with Fujitsu's F2MC-8FX debug adapters. It enables full breakpoint, step, and memory inspection capabilities without requiring JTAG pins or additional debug circuitry on the target board.
