FAQ

What is the maximum operating frequency supported by the M301N2F8TFP#U7?

The M301N2F8TFP#U7 supports a maximum external clock frequency of 16 MHz on the XIN pin, delivering a shortest instruction execution time of 62.5 ns. This timing is guaranteed across the full 4.2–5.5 V supply range and industrial temperature grade, making it suitable for deterministic automotive control loops where jitter-free timing is essential. The M301N2F8TFP#U7 does not support PLL-based frequency multiplication.

Does the M301N2F8TFP#U7 include a hardware CAN controller?

Yes, the M301N2F8TFP#U7 integrates a single-channel CAN 2.0B-compliant controller with full message object management (16 message objects), acceptance filtering, and error confinement logic. It supports both standard and extended identifiers and operates at bit rates up to 1 Mbps. The CAN physical layer requires an external transceiver; pins P02/P03 or P50/P51 serve as CTx/CRx signals under software configuration via CIOSR register.

What package type is used for the M301N2F8TFP#U7?

The M301N2F8TFP#U7 is housed in a 48-pin plastic mold LQFP package designated as 48P6Q-A per Renesas documentation. It measures 7.0 × 7.0 mm with 0.5 mm lead pitch, conforms to JEDEC MS-026AC, and features gull-wing leads suitable for standard SMT assembly. No thermal pad or exposed die attach is present.

How much on-chip memory does the M301N2F8TFP#U7 provide?

The M301N2F8TFP#U7 includes 64 KB of on-chip Flash memory for program storage and 3 KB of on-chip RAM for data and stack operations. Flash memory is organized to support in-system programming via dedicated control registers (FMR0–FMR4), while RAM spans addresses 00400–00FFF₁₆ and is used for variable storage, interrupt stacks, and CAN message buffers during runtime execution of M301N2F8TFP#U7 firmware.

Is the M301N2F8TFP#U7 qualified for automotive applications?

Yes, the M301N2F8TFP#U7 carries the "T" suffix in its part number, indicating qualification for automotive use per Renesas quality grading. It meets AEC-Q100 stress test requirements and is rated for operation across –40°C to +105°C ambient temperature. Its 4.2–5.5 V operating range aligns with automotive battery voltage transients defined in ISO 7637-2, and its CAN controller supports diagnostic communication per ISO 15765-2.
