FAQ
What is the maximum operating frequency of the M306NNFHGP#U3?
The M306NNFHGP#U3 achieves a minimum instruction execution time of 41.7 ns at 24 MHz BCLK, corresponding to a maximum core operating frequency of 24 MHz. Its on-chip PLL allows internal clock multiplication, but the BCLK limit remains 24 MHz per Renesas specification REJ03B0061-0210 Rev.2.10. The M306NNFHGP#U3 does not support frequencies beyond this rating.
Does the M306NNFHGP#U3 support in-circuit programming via standard interfaces?
Yes, the M306NNFHGP#U3 supports in-system programming (ISP) using the on-chip debug interface via the RXD0/TXD0 pins (P6_2/P6_3) and the RESET pin. Programming voltage is 3.3 ± 0.3 V or 5.0 ± 0.5 V, and flash endurance is rated for 100 write/erase cycles. No external high-voltage programmer is required for field updates.
How many CAN message objects does the M306NNFHGP#U3 support?
The M306NNFHGP#U3 implements one CAN 2.0B controller with 32 message object buffers, configurable as transmit or receive objects. Each buffer supports identifier masking, acceptance filtering, and automatic retransmission. This configuration is fixed and documented in the M16C/6N Group hardware manual REJ03B0061-0210.
Is the M306NNFHGP#U3 pin-compatible with other members of the M16C/6N Group?
No - the M306NNFHGP#U3 uses the 128-pin PLQP0128KB-A package, while 100-pin variants like M306NLFHGP use PLQP0100KB-A. Pin assignments differ significantly: P11–P14 ports and additional UART/CLK pins exist only on the 128-pin version. Direct PCB replacement is not possible without layout revision.
What is the role of the BYTE pin on the M306NNFHGP#U3?
The BYTE pin on the M306NNFHGP#U3 selects external data bus width: logic low configures a 16-bit bus (D0–D15 active), logic high configures an 8-bit bus (D0–D7 only). It is sampled during reset and determines whether the MCU operates in 16-bit or 8-bit external memory mode - critical for compatibility with legacy SRAM or peripheral ICs.
