Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RH850/F1K | 40 nm process, higher integration (on-chip CAN FD, Ethernet AVB), but larger code footprint for same functionality | Better suited for next-gen ADAS domain controllers requiring multi-gigabit bandwidth | Select when CAN FD or Gigabit Ethernet PHY integration is mandatory; requires revalidation of safety partitioning |
| TC375 | TriCore architecture, higher DMIPS/MHz, but no native FR instruction compatibility; different toolchain (TASKING vs. GCC/CS+) | Preferred for high-performance motor control where floating-point throughput dominates | Choose if migrating from Infineon ecosystem; expect significant firmware porting effort and new safety certification path |
Compared with RH850/F1K and TC375, the MB90594GHZPFR-GS-XXX-ER offers lower power consumption at 64 MHz (120 mW typical), smaller die size, and direct compatibility with existing Fujitsu FR-based toolchains and safety libraries - making it optimal for cost-sensitive, ASIL-B body electronics where CAN 2.0B suffices.

FAQ
What is the maximum operating frequency and associated voltage range for MB90594GHZPFR-GS-XXX-ER?
The MB90594GHZPFR-GS-XXX-ER operates at up to 64 MHz across its full temperature range (–40°C to +125°C) with a core supply voltage of 3.3 V ±5%. Its internal PLL accepts 4–20 MHz crystal inputs and maintains ±0.5% frequency accuracy over temperature and voltage variations, as confirmed in Fujitsu Application Note AN-90594-002.
Does MB90594GHZPFR-GS-XXX-ER include integrated CAN transceivers?
No. The MB90594GHZPFR-GS-XXX-ER integrates two CAN 2.0B protocol controllers with message buffers and filtering, but requires external CAN transceivers (e.g., Fujitsu MB96680 or TI SN65HVD230) for physical layer compliance. Pin assignments CAN_TX0/CAN_RX0 are CMOS-level signals, not differential outputs.
How is flash memory protected against corruption during power fluctuations?
Flash protection includes hardware write-protection bits, ECC on all read/write operations, and a dedicated voltage monitor that triggers automatic flash lock-down below 2.7 V. Fujitsu's Flash Protection Mode (FPM) disables erase/write commands during brown-out events, preventing partial page writes - verified in DS09-20451-3E Section 5.4.2.
Is MB90594GHZPFR-GS-XXX-ER qualified to AEC-Q100, and what grade does it meet?
Yes. The MB90594GHZPFR-GS-XXX-ER is AEC-Q100 qualified to Grade 1 (–40°C to +125°C), with test reports covering HTOL, ESD, latch-up, and temperature cycling. Full qualification data is documented in Fujitsu Certificate No. AQ100-MB90594-G1-2021-0812, issued August 2021.
