FAQ

What is the maximum operating frequency and corresponding instruction cycle time for M301N2F8VFP#U3?

The M301N2F8VFP#U3 supports a maximum external clock input of 16 MHz at the XIN pin. At this frequency, its shortest instruction execution time is 62.5 ns. This timing assumes operation within the specified 4.2 V to 5.5 V supply range and proper decoupling per the datasheet layout guidelines. The M301N2F8VFP#U3 achieves this performance using its on-chip M16C/60 CPU core with optimized pipeline and memory access.

Does M301N2F8VFP#U3 include an integrated CAN controller, and what version does it support?

Yes, the M301N2F8VFP#U3 integrates a single CAN 2.0B-compliant controller supporting both standard (11-bit) and extended (29-bit) identifiers. It features 16 message objects, hardware acceptance filtering, transmit/receive error counters, and status registers. The CAN I/O pins can be assigned to either P02/P03 or P50/P51 via software configuration, offering PCB layout flexibility. This makes M301N2F8VFP#U3 suitable for automotive network nodes and industrial fieldbus gateways.

How much Flash memory and RAM does M301N2F8VFP#U3 provide, and where are they mapped in the memory space?

The M301N2F8VFP#U3 contains 64 KB of on-chip Flash ROM, mapped from address F0000₁₆ to FFFFF₁₆, and 3 KB of on-chip RAM, mapped from 00400₁₆ to 00FFF₁₆. The Flash includes dedicated control registers (FMR0–FMR4) for programming and erase operations. The RAM area serves both data storage and stack usage for subroutine calls and interrupts. This memory map is fixed and documented in the M16C/1N Group hardware manual for M301N2F8VFP#U3.

What analog peripherals are integrated into M301N2F8VFP#U3, and how many channels do they support?

The M301N2F8VFP#U3 integrates a 12-channel 10-bit successive-approximation A/D converter with internal reference voltage input (VREF), and a single 8-bit D/A converter. The ADC supports software expansion to 14 channels using external analog multiplexing controlled by GPIOs like P40/P41 (ANEX0/ANEX1). These peripherals are accessed via dedicated SFRs (ADCON0–2, AD, DACON, DA) and support interrupt-driven conversions. This analog capability makes M301N2F8VFP#U3 well-suited for sensor interface applications without external converters.

Is M301N2F8VFP#U3 pin-compatible with other members of the M16C/1N group, such as M301N2F8TFP or M301N2M8T?

Yes, M301N2F8VFP#U3 shares the identical 48-pin LQFP (48P6Q-A) package and pinout with other M16C/1N group variants including M301N2F8TFP and M301N2M8T. All share the same I/O port assignments, peripheral pin mappings (e.g., CAN on P02/P03 or P50/P51), and power/reset signaling. Differences lie solely in memory type (Flash vs. Mask ROM) and size - not in electrical or mechanical compatibility. Therefore, M301N2F8VFP#U3 can be used as a drop-in replacement in existing M16C/1N designs where Flash programmability is required.
