FAQ

Does MB90F543GSPF-GS-9016 support CAN FD?

No. The MB90F543GSPF-GS-9016 implements FULL-CAN compliant with ISO 11898-1:2003 (CAN V2.0A and V2.0B), supporting up to 1 Mbps classical CAN frames only. It does not include CAN FD arbitration or data phase extensions, nor does its message buffer architecture accommodate FD frame formatting or bit-rate switching logic.

What is the maximum system clock frequency and how is it generated?

The MB90F543GSPF-GS-9016 achieves a maximum system clock of 16 MHz using its on-chip PLL, which multiplies an external 4 MHz crystal input by ×4. The PLL also supports ×1, ×2, ×3, and ÷2 modes, allowing flexible clock scaling for low-power operation while maintaining 62.5 ns minimum instruction execution time at full speed.

How is Flash memory protected during programming or field updates?

Flash protection is implemented via block-level write/erase lock controlled by externally applied programming voltage (Vpp) on designated pins. Each block can be independently erased, and the boot sector is hardware-reserved with fixed reset vector. Completion of erase/write operations is signaled by a dedicated status flag, enabling safe firmware rollback on failure.

Can the 8/10-bit A/D converter operate synchronously with timer events?

Yes. The A/D converter supports external trigger start via dedicated input pins (e.g., TIN0), allowing precise synchronization with timer overflow, input capture, or PPG output events. This enables deterministic sampling aligned to mechanical or electrical cycles - critical for engine position sensing and motor phase current measurement.
