Product details
Overview
MB90803PF-G-130E1 from Fujitsu Semiconductor is a 16-bit F2MC-16LX microcontroller with integrated LCD controller (48-segment × 4-common), 4 KB RAM, 128 KB ROM, 32-bit accumulator, and PLL clock multiplier supporting up to 25 MHz operation at 3.3 V. It targets industrial automation and office equipment requiring real-time control, low-power modes, and direct LCD drive.
For engineers reviewing the MB90803PF-G-130E1 datasheet, MB90803PF-G-130E1 pinout, MB90803PF-G-130E1 application, or MB90803PF-G-130E1 equivalent, key selection criteria include its 100-pin QFP package, 2.7–3.6 V supply range, 12-channel 8/10-bit ADC, dual UARTs, and programmable interrupt priority for deterministic embedded control.
Technical Context
The MB90803PF-G-130E1 implements the F2MC-16LX architecture with 23 addressing modes, symmetry and barrel-shift instructions, and instruction set compatibility with C language and multitasking. Its 32-bit accumulator enables high-precision arithmetic without software emulation.
It integrates dedicated peripherals including an LCD controller with segment/common drivers, two 16-bit input-capture units (ICU), two output-compare units (OCU), three 16-bit reload timers with external event output, and two PPG timers - all synchronized to the same internal clock domain for deterministic timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB90F804-101 | 256 KB FLASH vs. 128 KB ROM; same pinout and peripheral set | Field-upgradable firmware required vs. mask-ROM cost optimization | Select for prototyping or production runs needing firmware updates post-deployment |
| MB90802S | 128 KB ROM but only 2 KB RAM and no built-in LCD controller | Requires external LCD driver; lower memory footprint for simpler control tasks | Select when LCD drive is unnecessary and BOM cost reduction outweighs integration benefits |
Compared with MB90F804-101 and MB90802S, the MB90803PF-G-130E1 uniquely balances mask-ROM cost efficiency, integrated LCD drive, and sufficient RAM (4 KB) for real-time HMI buffering - making it optimal for fixed-function industrial displays where flash flexibility is unnecessary but display integration is critical.

Manufacturer
Fujitsu Semiconductor (now part of Socionext Inc. following 2017 acquisition) designed high-reliability microcontrollers for industrial and automotive applications with emphasis on real-time determinism and mixed-signal integration.
The MB90800 Series was developed specifically for cost-sensitive, high-volume industrial automation and office equipment requiring integrated LCD control, low-power operation, and deterministic interrupt response - not general-purpose computing.
FAQ
What is the minimum supply voltage for reliable operation of MB90803PF-G-130E1?
The device operates reliably from 2.7 V to 3.6 V over the full industrial temperature range (−40°C to +85°C). Below 2.7 V, internal voltage regulators and oscillator circuits may fail to stabilize, causing unpredictable reset behavior or LCD contrast loss. The datasheet specifies 2.7 V as the absolute minimum for guaranteed functional operation under all conditions.
Does MB90803PF-G-130E1 support in-system programming (ISP)?
No. The MB90803PF-G-130E1 contains mask-programmed ROM, not FLASH or EEPROM. Firmware is permanently written during wafer fabrication and cannot be modified after packaging. For field-upgradable designs, Fujitsu offered the MB90F804-101 variant with 256 KB on-chip FLASH memory and identical pinout.
Can the built-in LCD controller drive a 64-segment display?
No. The controller is hardwired for exactly 48 segments and 4 commons. Attempting to drive more segments requires external segment drivers or multiplexing logic. The pin assignment confirms only SEG0–SEG47 are available, with no provision for additional segment outputs beyond that count.
How many simultaneous UART channels can operate independently?
Two full-duplex UART channels operate independently with separate transmit/receive buffers, baud rate generators, and interrupt vectors. Each supports asynchronous mode with start/stop bits and synchronous mode with external clock input. No shared resources limit concurrent operation - both can transmit and receive simultaneously without contention.
