FAQ

What is the minimum instruction execution time for MB90387SPMT-G-388SN-YE1?

The minimum instruction execution time is 62.5 ns, achieved when operating with a 4-MHz crystal and 4× PLL multiplication to generate a 16-MHz machine clock. This timing applies to basic instructions such as register-to-register moves and is confirmed in the AC Characteristics section of the official datasheet (Document Number 002-07765 Rev. *A, Page 60).

Does MB90387SPMT-G-388SN-YE1 support CAN wake-up from stop mode?

Yes, it supports CAN wake-up from stop mode via dedicated CAN wakeup interrupt (1 channel). The CAN controller remains active enough to detect dominant bits on the bus while CPU and oscillation clock are halted, allowing immediate resumption of CAN message processing upon wake-up event.

How many analog input channels does the integrated ADC support?

The integrated 8/10-bit ADC supports exactly 8 analog input channels (AN0–AN7), mapped to port P50–P57. Resolution is selectable per conversion sequence, and sequential conversion across all 8 channels is supported with programmable channel order and trigger source (software, timer, or external pin).

Is an external crystal required for CAN timing compliance?

Yes - a stable 4-MHz crystal connected to X0/X1 is required to achieve the 16-MHz machine clock needed for CAN bit timing accuracy across the full 10 kbps–1 Mbps range. Internal RC oscillators lack the stability required for CAN physical layer conformance per ISO 11898-1.
