Product details
Overview
MB91F469GBPB-GSER-270571 from Fujitsu is a 32-bit automotive-grade FR70 RISC microcontroller in the MB91460 series, featuring 2112 kB embedded flash, 96 kB RAM, 32-channel ADC, 6-channel CAN (C-CAN), and operation up to 100 MHz at -40°C to +125°C. It targets high-integrity body control and gateway applications requiring AEC-Q100 qualification, on-chip EDSU debugging, and FlexRay-ready peripheral integration.
For engineers reviewing the MB91F469GBPB-GSER-270571 datasheet, MB91F469GBPB-GSER-270571 pinout, MB91F469GBPB-GSER-270571 application, or MB91F469GBPB-GSER-270571 equivalent, key selection criteria include its 6-channel C-CAN support, 320-pin BGA package with 28A/32D external bus interface, 2112 kB flash with 10,000 write/erase cycles, and integrated clock modulator for EME reduction.
Technical Context
The MB91F469G implements Fujitsu's FR70 core with 5-stage pipeline and prefetch/cache architecture enabling zero-wait-cycle execution from internal flash. Its memory subsystem includes 2112 kB flash (organized in 64 kB and 8 kB sectors), 96 kB SRAM, and 4 kB + 16 kB cache - optimized for deterministic real-time response in automotive gateways.
Peripheral integration centers on multi-domain timing: dual-clock domains (main 100 MHz + sub-clock option), hardware watchdog based on independent RC oscillator, voltage supervision with low-voltage detection and alarm comparator, and clock supervision - all supporting ISO 26262 ASIL-B–capable system design.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RH850/F1K | 400 MHz dual-core, 2 MB flash, built-in ECC RAM, but no external bus interface | Lacks 28A/32D EBI - unsuitable for graphics/FlexRay ASSP interfacing | Select when safety certification (ISO 26262 ASIL-D) and dual-core lockstep are mandatory over peripheral flexibility |
| S32K344 | Arm Cortex-M7, 4 MB flash, 512 kB RAM, CAN FD only (no legacy CAN), no external bus | No C-CAN or EBI - cannot replace MB91F469G in legacy gateway designs with FlexRay ASSP coupling | Prefer for new CAN FD–centric architectures requiring Arm ecosystem tools and AUTOSAR Classic/Adaptive support |
Compared with RH850/F1K and S32K344, MB91F469GBPB-GSER-270571 uniquely combines 6-channel legacy CAN, 320-pin BGA with full EBI, and AEC-Q100 Grade 0 operation - making it irreplaceable in existing FlexRay-assisted gateway platforms requiring backward compatibility and high peripheral density.

FAQ
What is the maximum ambient temperature rating for MB91F469GBPB-GSER-270571?
The device is qualified to AEC-Q100 Grade 0 with guaranteed operation from -40°C to +125°C. This rating is validated through accelerated life testing and thermal cycling per JESD22-A104, and applies to all operating modes including full-speed 100 MHz execution with all peripherals active.
Does MB91F469GBPB-GSER-270571 support CAN FD or only classical CAN?
MB91F469GBPB-GSER-270571 implements six channels of classical C-CAN (Controller Area Network) compliant with ISO 11898-1:2003, supporting data rates up to 1 Mbps. It does not include CAN FD controllers; CAN FD capability requires external transceivers and protocol stack implementation in software.
Is an external crystal required for real-time clock operation?
Yes - the RTC module supports two clock sources: an optional external 32.768 kHz crystal (for high-accuracy timekeeping) or the internal low-power RC oscillator (for basic timestamping when crystal is omitted). Both sources are selectable via register configuration in the RTC control block.
What debug interface does MB91F469GBPB-GSER-270571 use for on-chip programming?
The device uses the EDSU (Embedded Debug Support Unit) macro, accessible via JTAG/SWD-compatible debug probes such as Accemic MDE or Green Hills Super Trace Probe. Flash programming is performed through the EDSU using standard SWD commands; no external bootloader or UART-based flashing is required.
