Overview
M306N4FGVFP#UKJ from Renesas Electronics is a 16-bit Flash-based microcontroller in the M16C/6N Group (M16C/6N4), featuring dual CAN 2.0B modules, 256 KB + 4 KB data flash memory, 10 KB RAM, and operation up to 24 MHz (VCC = 4.2–5.5 V). It integrates a 10-bit 26-channel A/D converter, dual 8-bit D/A converters, five 16-bit timer A channels, six 16-bit timer B channels, three-phase motor control circuitry, and DMAC for automotive body control and industrial motion systems.
For engineers reviewing the M306N4FGVFP#UKJ datasheet, M306N4FGVFP#UKJ pinout, M306N4FGVFP#UKJ application, or M306N4FGVFP#UKJ equivalent, key selection considerations include its V-ver. grade (−40°C to +125°C), 100-pin QFP package (PRQP0100JB-A), dual-CAN support for fault-tolerant vehicle networks, and integrated analog peripherals enabling closed-loop motor and sensor interface without external signal conditioning.
Technical Context
The M306N4FGVFP#UKJ implements the M16C/60 Series CPU core with 91 fundamental instructions and minimum instruction execution time of 41.7 ns at 24 MHz. Its dual CAN controllers operate independently per ISO 11898-1:2003 (CAN 2.0B), supporting both standard and extended frames with programmable message objects and automatic retransmission.
It features four clock generation circuits - main crystal oscillator (XIN/XOUT), sub-crystal oscillator (XCIN/XCOUT), on-chip oscillator, and PLL frequency synthesizer - enabling flexible system timing with oscillation-stopped detection. The peripheral set includes three serial interfaces (UART, I²C-bus, IEBus), CRC-CCITT calculation circuit, and watchdog timer with 15-bit counter and prescaler.

FAQ
What is the maximum operating frequency and supply voltage range for the M306N4FGVFP#UKJ?
The M306N4FGVFP#UKJ operates at up to 24 MHz with a supply voltage range of 4.2 V to 5.5 V under V-ver. conditions. This specification ensures stable high-speed execution in automotive under-hood environments where voltage regulation and thermal stability are critical. The M306N4FGVFP#UKJ achieves 41.7 ns minimum instruction execution time at this frequency, enabling tight real-time loop deadlines.
Does the M306N4FGVFP#UKJ support CAN FD or only classical CAN 2.0B?
The M306N4FGVFP#UKJ supports only CAN 2.0B (ISO 11898-1:2003), not CAN FD. Its dual CAN modules implement full 2.0B functionality including standard/extended frame support, 32 message objects per channel, and automatic retransmission. The M306N4FGVFP#UKJ does not include CAN FD arbitration or data phase enhancements, making it suitable for legacy automotive networks but not next-generation high-bandwidth applications.
How much data flash memory is integrated into the M306N4FGVFP#UKJ, and what is its purpose?
The M306N4FGVFP#UKJ integrates 4 KB of dedicated data flash memory (block A), separate from main program flash. This area is designed for frequent read/write operations such as calibration data, runtime configuration, or event logs - preserving endurance of main flash. The M306N4FGVFP#UKJ supports 100 erase/write cycles for this block, enabling field updates without requiring external EEPROM.
What is the role of the three-phase motor control circuit in the M306N4FGVFP#UKJ?
The three-phase motor control circuit in the M306N4FGVFP#UKJ provides hardware-assisted commutation timing, dead-time insertion, and fault protection for BLDC and PMSM motors. It directly interfaces with external gate drivers using U/V/W output pins and accepts hall sensor or encoder feedback via TA0–TA4 inputs. This reduces firmware complexity and improves timing precision compared to software-based PWM generation in the M306N4FGVFP#UKJ.
Is the M306N4FGVFP#UKJ qualified for automotive applications, and what temperature grade does it carry?
Yes, the M306N4FGVFP#UKJ carries the V-ver. grade, qualifying it for automotive applications with ambient operating temperatures from −40°C to +125°C. This meets AEC-Q100 stress testing requirements for under-hood deployment. The M306N4FGVFP#UKJ is explicitly designated for automotive use in Renesas documentation and is commonly deployed in body control modules, electric power steering, and HVAC actuators.
