FAQ

What is the maximum operating frequency of the R4F24245DFPV?

The R4F24245DFPV supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip PLL with an external crystal (1–20 MHz) or ceramic resonator. Internal oscillator mode limits operation to 20 MHz. All timing specifications - including Flash access, peripheral operation, and I/O setup/hold - are guaranteed across the full 32 MHz range when powered within the 2.7–5.5 V supply range.

Does the R4F24245DFPV include hardware debug support?

Yes, the R4F24245DFPV integrates Renesas' On-Chip Debug Support (OCDS) with full breakpoint, watchpoint, and trace capabilities. Debug access uses dedicated pins (TCK, TDO, TDI, TMS) compatible with standard JTAG adapters. The OCDS module allows non-intrusive program execution monitoring and real-time register/memory inspection without requiring additional debug firmware overhead.

What are the power supply requirements for the R4F24245DFPV?

The R4F24245DFPV requires two separate supply domains: VCC1 (core logic, 2.7–3.6 V) and VCC2 (I/O ports, 2.7–5.5 V). This dual-voltage architecture allows direct interfacing with both 3.3 V peripherals and legacy 5 V systems. Decoupling capacitors (0.1 μF ceramic + 4.7 μF tantalum per VCC pair) are mandatory per Renesas layout guidelines to ensure stable operation at 32 MHz.

Is the R4F24245DFPV pin-compatible with other H8S/2424 family members?

Yes, the R4F24245DFPV is fully pin-compatible with all 100-pin LQFP variants in the H8S/2424 Group, including R4F24244DFPV and R4F24246DFPV. Identical pin assignments, electrical characteristics, and peripheral mapping allow drop-in replacement - only Flash and RAM capacities differ, verified by reading the device ID register at startup.

What peripheral interfaces does the R4F24245DFPV support for industrial communication?

The R4F24245DFPV supports dual Serial Communication Interface (SCI) modules compliant with UART/RS-232/RS-485 physical layers, each capable of baud rates up to 2 Mbps. It also includes a 16-bit Timer Pulse Unit (TPU) for encoder input capture and PWM generation, and an 8-channel 10-bit ADC for analog sensor interfacing - collectively enabling complete fieldbus node implementation without external interface ICs.
