FAQ

What is the maximum operating frequency of the R5F72433D100FP#U0?

The R5F72433D100FP#U0 operates at a maximum frequency of 80 MHz, achieved using its integrated Clock Pulse Generator (CPG) with PLL-based clock synthesis from an external 4–20 MHz crystal. This frequency enables deterministic execution of real-time control algorithms with sub-microsecond interrupt latency, and is validated across the full industrial temperature range (−40°C to +85°C) per Renesas' hardware specifications.

Does the R5F72433D100FP#U0 include a CAN controller?

Yes, the R5F72433D100FP#U0 integrates a fully compliant CAN 2.0B controller supporting bit rates up to 1 Mbps, message filtering, and automatic retransmission. It interfaces directly to external CAN transceivers via dedicated CAN_TX and CAN_RX pins, and is used in industrial networked systems such as distributed motor drives and PLC backplanes where robust differential signaling is required.

What package type and pin count does the R5F72433D100FP#U0 use?

The R5F72433D100FP#U0 uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This package supports industrial thermal dissipation requirements and provides dedicated power/ground pairs, analog/digital separation, and 80 general-purpose I/O pins - matching the pinout of other SH7243 Group devices including R5F72423D100FP#U0 and R5F72434D100FP#U0 for drop-in scalability.
