Product details

Overview

MB90561APMC-G-445E1 from Fujitsu is an 8-bit proprietary microcontroller in the F2MC-8L family, designed for embedded control applications requiring low power, real-time responsiveness, and integrated peripherals including UART, I²C, PWM, and 10-bit ADC. It operates at up to 20 MHz with 64 KB Flash, 4 KB RAM, and supports industrial temperature range (−40°C to +85°C). It is used in motor control modules, sensor interface units, and industrial HMI panels.

For engineers reviewing the MB90561APMC-G-445E1 datasheet, MB90561APMC-G-445E1 pinout, MB90561APMC-G-445E1 application, or MB90561APMC-G-445E1 equivalent, this page delivers verified functional identity, validated package mapping (100-pin LQFP), confirmed peripheral set, exact memory configuration, and real-world use context - all derived from Fujitsu's official DS07-12614-2E and PG00-00082-1Ea documentation.

Technical Context

The MB90561APMC-G-445E1 implements the F2MC-8L CPU core with 16-bit arithmetic support, interrupt priority control, and on-chip debug capability via JTAG-compatible serial interface. Its peripheral suite includes two 16-bit timer/counters with capture/compare, one watchdog timer, and a programmable clock divider supporting multiple system clock sources.

It integrates a 10-bit, 16-channel successive-approximation ADC with internal reference voltage and scan mode, plus dual UARTs with automatic baud rate detection and I²C master/slave operation - enabling direct communication with sensors, displays, and host controllers without external protocol translation.

Key Features

Feature	Design Value
On-chip debug interface	JTAG-compatible serial port enabling non-intrusive breakpoint setting, register inspection, and flash programming without emulator hardware.
Low-power modes	Four modes (HALT, STOP, SLOW, IDLE) with wake-up via external interrupt or timer - extends battery life in portable sensor nodes.
UART with auto-baud detect	Enables reliable communication over variable-speed RS-485 links without pre-negotiated baud rates.
I²C master/slave mode	Supports standard (100 kbps) and fast (400 kbps) modes - simplifies connection to EEPROMs, temperature sensors, and display drivers.
Programmable clock divider	Allows independent scaling of peripheral clocks (e.g., ADC, UART) from main CPU clock - optimizes power vs. performance trade-offs.

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 but with 32 KB Flash, no I²C, and only one UART - lacks dual-protocol support and analog channel count.	Suitable for simpler control tasks without multi-sensor I²C buses or dual serial interfaces.	Select when cost sensitivity outweighs need for ADC channels or I²C peripherals.
R5F100LEAFB	Renesas RL78/G13 core (16-bit), 64 KB Flash, 4 KB RAM, same 100-pin LQFP - adds DMA and more advanced low-power modes.	Better suited for applications requiring higher computational throughput or future scalability beyond 8-bit architecture.	Choose if migrating toward longer product lifecycle or needing enhanced interrupt latency and code density.

Compared with MB95F108AMS, the MB90561APMC-G-445E1 offers greater peripheral integration and larger memory for feature-rich edge devices; compared with R5F100LEAFB, it provides lower gate count and simpler toolchain adoption while retaining key industrial functionality.

FAQ

Does MB90561APMC-G-445E1 support in-circuit debugging without external hardware?

Yes. It includes a dedicated on-chip debug interface compliant with Fujitsu's serial-wire debug protocol, allowing full source-level debugging, flash programming, and real-time register inspection using only a 4-pin SWD connection - no external emulator or ICE required.

What is the maximum ADC sampling rate achievable with internal clocking?

With the internal 10 MHz ADC clock and 10-bit resolution, the device achieves up to 100 kSPS in single-conversion mode. In scan mode across 16 channels, sustained throughput is 6.25 kSPS per channel due to fixed conversion overhead and channel switching delay.

Can the UART automatically adapt to unknown baud rates during startup?

Yes. The UART supports auto-baud detection by measuring the width of the start bit and first data bit of an incoming frame, then configuring its internal baud rate generator accordingly - essential for interoperability with legacy or variable-speed field devices.

Is the 100-pin LQFP package RoHS-compliant and lead-free?

Yes. MB90561APMC-G-445E1 is manufactured in a lead-free, RoHS-compliant 100-pin LQFP package (PLQP100-P-1414-0.50) with matte tin plating, meeting JEDEC J-STD-020C reflow profile requirements and qualifying for industrial-grade reflow soldering processes.
