Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144 | ARM Cortex-M4F core, 512 KB Flash, single CAN FD channel, AEC-Q100 Grade 1 | Supports CAN FD (5 Mbps) but lacks second classical CAN channel; requires external transceiver for dual-CAN topology | Select when CAN FD bandwidth or floating-point math acceleration is required over dual classical CAN redundancy |
| Renesas RL78/F14 | 16-bit RL78 core, 256 KB Flash, single CAN 2.0B channel, integrated LINPHY | No native dual-CAN support; relies on software-managed time-division multiplexing across one CAN peripheral | Select for cost-sensitive body electronics where LIN coexistence outweighs dual-CAN determinism needs |

FAQ
What is the maximum CAN bit rate supported by MB90F543GSPF-GE1?
The MB90F543GSPF-GE1 supports up to 1 Mbps on each of its two FULL-CAN channels, compliant with ISO 11898-1 V2.0A/B. Bit timing is programmable via BTR registers, and the internal clock source (16 MHz PLL output) provides sufficient resolution for precise synchronization across automotive networks.
Does MB90F543GSPF-GE1 support CAN FD?
No, MB90F543GSPF-GE1 implements classical CAN 2.0A/B only and does not support CAN FD features such as variable bit rates or extended data length. Its dual-CAN architecture is optimized for legacy and current-generation automotive networks operating at ≤1 Mbps.
How is Flash memory protected against accidental erasure during operation?
Flash protection uses external programming voltage (Vpp) applied to the MD0–MD2 pins to enable block erase/write operations. Without Vpp, all Flash sectors remain read-only; the boot block is further secured by a hard-wired reset vector that always points to fixed startup code regardless of Flash state.
Can MB90F543GSPF-GE1 operate from a 3.3 V supply?
No - MB90F543GSPF-GE1 requires 4.5 V to 5.5 V operation per datasheet specification (Document 002-07696 Rev. *B, Page 6). It is not compatible with 3.3 V logic families and must be powered from a regulated 5 V rail meeting automotive transient requirements.
