FAQ

What is the maximum operating frequency of the R4F2463VTE34DV#GZ?

The R4F2463VTE34DV#GZ operates at a maximum CPU clock frequency of 32 MHz, achieved using its on-chip PLL with external crystal input (1–20 MHz). At this speed, it delivers 32 MIPS performance while maintaining full functionality of all peripherals including CAN, SCI, and TPU. The R4F2463VTE34DV#GZ supports wait-state-free access to on-chip RAM and flash at this frequency, enabling deterministic real-time execution.

Does the R4F2463VTE34DV#GZ support in-system programming via CAN?

Yes, the R4F2463VTE34DV#GZ supports in-application programming (IAP) that allows firmware updates over CAN or SCI without requiring external programming hardware. Its 256 KB flash is organized into sectors enabling erase/write operations while executing code from other protected sectors. The R4F2463VTE34DV#GZ includes dedicated ROM-resident bootloader routines accessible via CAN message ID 0x7FF, compliant with SAE J2411 for automotive diagnostics.

What is the CAN bit-rate range supported by the R4F2463VTE34DV#GZ?

The R4F2463VTE34DV#GZ CAN controller supports bit rates from 10 kbps to 1 Mbps, configurable via programmable prescaler and time-segment registers. It complies fully with ISO 11898-1 (CAN 2.0B) and supports both standard (11-bit) and extended (29-bit) identifier formats. The R4F2463VTE34DV#GZ achieves ±0.1% bit-timing accuracy at 500 kbps using its internal clock source, meeting OEM requirements for body control networks.

How many analog input channels does the R4F2463VTE34DV#GZ ADC support?

The R4F2463VTE34DV#GZ integrates a 10-bit successive-approximation ADC with 16 selectable input channels (AD0–AD15), multiplexed onto port P1 and P2 pins. Conversion time is fixed at 1.2 µs per sample, and the ADC supports hardware-triggered sampling synchronized to TPU events or timer overflows. The R4F2463VTE34DV#GZ ADC includes built-in offset calibration and supports differential input mode on selected channel pairs.

Is the R4F2463VTE34DV#GZ pin-compatible with other H8S/246x series devices?

Yes, the R4F2463VTE34DV#GZ is pin-compatible with the R4F2462VTE34DV#GZ and R4F2472VTE34DV#GZ in the same 100-pin LQFP package, sharing identical pin assignments for power, reset, clocks, CAN, SCI, and ADC functions. However, some peripheral signals (e.g., additional TPU channels or extra SCI lines) are no-connect on the R4F2462VTE34DV#GZ and reserved on the R4F2463VTE34DV#GZ. The R4F2463VTE34DV#GZ maintains full PCB layout compatibility across this family.
