Product details
Overview
MB91F469GBPB-GS-N2-K6 from Fujitsu is a 32-bit automotive-grade MCU based on the FR70 RISC core, operating up to 100 MHz with 2112 kB embedded flash, 96 kB RAM, and 4 kB + 16 kB cache. It integrates 6-channel CAN (C-CAN), 8-channel LIN-USART, 4-channel I²C, 32-channel ADC, 16-channel PPG, and supports FlexRay via external ASSP coupling. It targets dashboard instrumentation and body control units in vehicles operating from −40°C to +125°C.
For engineers reviewing the MB91F469GBPB-GS-N2-K6 datasheet, MB91F469GBPB-GS-N2-K6 pinout, MB91F469GBPB-GS-N2-K6 application, or MB91F469GBPB-GS-N2-K6 equivalent, key selection criteria include its AEC-Q100 qualification, dual-voltage domain support (3.3 V I/O / 1.8 V core), on-chip EDSU for debugging, bootROM-enabled field reprogramming, and integrated clock modulator for EME reduction.
Technical Context
The MB91F469GBPB-GS-N2-K6 implements Fujitsu's FR70 5-stage pipeline RISC core with bit-search and EDSU debug support. It features a prefetch/cache architecture enabling zero-wait-state execution from internal flash and uses an on-chip regulator to derive 1.8 V core voltage from a 3.3–5.5 V supply.
Its peripheral set includes a hardware watchdog driven by an independent RC oscillator, low-voltage detection with alarm comparator, clock supervision, flash security lock, and configurable external bus interface (28 address / 32 data lines) supporting graphics controllers and FlexRay ASSPs.

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 | 32-bit RXv2 core, 120 MHz, 2 MB flash, 384 kB RAM, built-in ECC on flash/RAM, no integrated EDSU | Stronger safety compliance (ISO 26262 ASIL-B ready), higher RAM density, but requires external debug probe (not EDSU-based) | Choose RH850/F1K when ASIL-B functional safety certification is mandatory and external debug infrastructure is available. |
| S32K144 | Cortex-M4F core, 112 MHz, 512 kB flash, 128 kB RAM, 1x CAN FD, 1x LIN, no external bus interface | Lower integration for cost-sensitive entry-tier BCMs; lacks FlexRay readiness and graphics bus support | Choose S32K144 for LIN/CAN-only body nodes where external bus expansion is unnecessary and Cortex toolchain preference exists. |
Compared with RH850/F1K and S32K144, MB91F469GBPB-GS-N2-K6 uniquely combines FlexRay ASSP coupling, 2112 kB flash for complex UIs, and EDSU-based on-chip debugging-making it optimal for high-integration dashboard and gateway designs requiring legacy protocol support and field-reprogrammable boot code.

FAQ
What is the maximum ambient temperature rating for MB91F469GBPB-GS-N2-K6?
The device is qualified for −40°C to +125°C ambient operation per AEC-Q100 Grade 0. This rating is verified across all electrical parameters in the official datasheet and applies to continuous operation-not just storage. Thermal derating is not required within this range, and the on-chip temperature sensor supports real-time monitoring.
Does MB91F469GBPB-GS-N2-K6 support CAN FD?
No, MB91F469GBPB-GS-N2-K6 integrates only classical C-CAN controllers compliant with ISO 11898-1:2003, supporting up to 1 Mbps. It does not implement CAN FD physical layer or protocol enhancements such as variable bit rate or extended data length. For CAN FD, Fujitsu recommends pairing with external transceivers and protocol stacks on companion SoCs.
Is external RAM required for typical dashboard applications?
No. With 96 kB on-chip SRAM and zero-wait-state access, the device supports full instrument cluster firmware-including graphics buffer management, CAN message queuing, and real-time stepper motor control-without external RAM. The external bus interface is optional and used only for graphics controllers or FlexRay ASSPs, not memory expansion.
How is flash security implemented on MB91F469GBPB-GS-N2-K6?
Flash security is enforced via hardware lock bits that disable read-out and programming of protected sectors. Once enabled, these bits are irreversible and prevent JTAG-based extraction. Security covers both user flash and bootROM regions. Unlocking requires physical chip replacement-no software override or backdoor exists, satisfying OEM anti-tampering requirements.
