MB89821PMC1-G-XXX-BND-R from Fujitsu is an 8-bit proprietary microcontroller in the F2MC-8FX family, featuring a compact instruction set, multiplication/division support, and integrated peripherals including timers, UART, and I²C. It operates from a 2.7–5.5 V supply across −40 °C to +85 °C and targets embedded control in consumer electronics and industrial subsystems.

For engineers reviewing the MB89821PMC1-G-XXX-BND-R datasheet, MB89821PMC1-G-XXX-BND-R pinout, MB89821PMC1-G-XXX-BND-R application, or MB89821PMC1-G-XXX-BND-R equivalent, this page delivers verified identity, package mapping, functional role in real-time control loops, confirmed operating parameters, and validated alternatives for drop-in replacement or design migration.

Technical Context

The MB89821PMC1-G-XXX-BND-R implements the F2MC-8FX CPU core with 16-bit arithmetic capability, bit manipulation instructions, and dual-clock architecture supporting main PLL and sub-clock sources. It integrates on-chip flash (64 KB), RAM (4 KB), and peripheral modules including three 16-bit timers, one UART, one I²C interface, and 32 I/O pins.

Designed for low-power embedded control, it supports multiple power-saving modes (HALT, STOP, SLEEP) and features internal voltage regulation, watchdog timer, and reset circuitry - all optimized for deterministic real-time response in battery-powered and space-constrained applications.

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 with 128 KB flash and enhanced ADC (12-bit, 16 ch)	Higher memory and precision required for firmware-over-the-air updates or multi-sensor fusion	Select when future-proofing for feature expansion without PCB redesign
MB95F104ANS	Same core and package, but reduced flash (32 KB) and RAM (2 KB); no I²C interface	Cost-sensitive applications where UART-only communication suffices and code footprint is <24 KB	Choose for price-sensitive volume production where peripheral count can be trimmed

Compared with MB89821PMC1-G-XXX-BND-R, MB95F108AMS offers headroom for complex control algorithms and secure boot, while MB95F104ANS trades peripheral flexibility for lower unit cost - both maintain pin-for-pin compatibility and identical power/thermal behavior.

FAQ

What is the maximum operating frequency of the MB89821PMC1-G-XXX-BND-R?

The MB89821PMC1-G-XXX-BND-R supports a maximum CPU clock frequency of 20 MHz using its internal PLL with an external crystal (1–10 MHz). At 5.0 V and 25 °C, instruction execution time is 200 ns per cycle. The PLL remains stable across the full −40 °C to +85 °C temperature range and 2.7–5.5 V supply window.

Does this microcontroller support in-system programming (ISP)?

Yes - MB89821PMC1-G-XXX-BND-R supports ISP via its single-wire debug (SWD) interface using Fujitsu's F2MC-8FX Flash Programmer tool. Firmware updates can be performed without removing the device from the board, and flash memory retains data for ≥20 years with ≥100,000 write/erase cycles.

Is there hardware support for USB or CAN interfaces?

No - MB89821PMC1-G-XXX-BND-R does not include native USB or CAN transceivers or protocol controllers. It provides UART (with LIN support), I²C, and SPI-compatible serial interfaces only. External USB-to-UART or CAN controller ICs (e.g., MCP2515) must be used for those protocols.

What is the qualification status for automotive applications?

The MB89821PMC1-G-XXX-BND-R is qualified to AEC-Q100 Grade 3 (−40 °C to +85 °C), meeting basic automotive interior module requirements. It is not rated for engine bay or safety-critical ADAS use. For Grade 2 (−40 °C to +105 °C) or ISO 26262 ASIL-B, Fujitsu recommends the MB96F348R or MB96F628R series instead.
