The M306N4MGT-165FPUFQ supports only Controller Area Network 2.0B (ISO 11898-1:2003), not CAN FD. Its dual CAN modules implement full 2.0B functionality including extended identifiers, error confinement, and message filtering - confirmed in Section 1.1 and Table 1.1 of the official Renesas documentation.
What package type and pin count does the M306N4MGT-165FPUFQ use?
The M306N4MGT-165FPUFQ uses the PRQP0100JB-A (100P6S-A) 100-pin plastic QFP package with 0.65 mm pitch. This is explicitly defined in Table 1.2 of the REJ03B0003-0240 datasheet, where "FP" in the part number suffix denotes this specific QFP variant.
Is the M306N4MGT-165FPUFQ qualified for automotive applications requiring AEC-Q100 certification?
Yes - the M306N4MGT-165FPUFQ is a V-version device rated for −40°C to +125°C and classified under Renesas' "Specific" quality grade, intended for automotive applications including engine control and powertrain systems. While AEC-Q100 test reports are not included in the public datasheet, Renesas confirms V-version parts meet automotive reliability requirements per internal qualification standards.
How much internal RAM and ROM does the M306N4MGT-165FPUFQ include?
The M306N4MGT-165FPUFQ contains 256 KB of mask ROM and 10 KB of on-chip RAM, as specified in Table 1.2 of the REJ03B0003-0240 datasheet. The "MG" in the part number indicates 256 KB ROM capacity, and "T" denotes the automotive temperature grade (V-version), with "FP" confirming the QFP package.
