FAQ
What is the maximum operating frequency of the M306NNFJGP#U3?
The M306NNFJGP#U3 achieves a minimum instruction execution time of 41.7 ns at 24 MHz BCLK with 1/1 prescaler and no software wait states. Its PLL frequency synthesizer enables stable operation up to 24 MHz from external crystal sources, and the CPU core supports this full frequency range for real-time deterministic processing.
Does the M306NNFJGP#U3 support CAN FD or only classical CAN 2.0B?
The M306NNFJGP#U3 implements only CAN 2.0B (ISO 11898-1:2003) and does not support CAN FD. Its CAN module provides full 2.0B functionality including extended identifier support, message object buffering, and automatic error confinement - sufficient for most automotive body and industrial control networks.
What is the flash endurance specification for the M306NNFJGP#U3?
The M306NNFJGP#U3 Flash memory has a guaranteed programming and erasure endurance of 100 cycles per block, as specified in the REJ03B0061-0210 datasheet. This applies to both main program memory and the dedicated 4 KB data flash block (Block A) used for parameter storage.
Can the M306NNFJGP#U3 operate from a 3.3 V supply only, or does it require 5 V?
The M306NNFJGP#U3 operates across a 3.0 V to 5.5 V supply range. It functions correctly at 3.3 V nominal, supporting modern low-voltage system designs; all I/O pins tolerate 5.0 V regardless of VCC level, enabling safe interfacing with legacy 5 V peripherals.
Is there an official replacement or successor part for the M306NNFJGP#U3?
Renesas has not announced a direct pin-compatible or functionally identical successor to the M306NNFJGP#U3. Customers seeking long-term supply should engage Renesas sales for lifecycle status; migration paths include the RL78/F1x or RA2 series, though these require PCB and firmware redesign due to architectural differences.
