FAQ

What is the operating temperature range for the R5F64189PFD?

The R5F64189PFD is qualified for operation from -40°C to +85°C (P version). This industrial-grade temperature rating ensures reliable performance in under-hood automotive environments and factory-floor industrial controls where ambient conditions exceed commercial limits. The device maintains full specification compliance-including CAN timing accuracy and A/D conversion linearity-across this entire range.

Does the R5F64189PFD include an on-chip floating-point unit?

Yes, the R5F64189PFD integrates an IEEE-754 compatible single-precision floating-point unit (FPU) as part of its R32C/100 Series CPU core. This hardware FPU accelerates trigonometric, exponential, and division operations critical for real-time audio processing, motor control algorithms, and sensor fusion-eliminating reliance on slower software libraries and reducing CPU load in the R5F64189PFD-based design.

How many CAN interfaces does the R5F64189PFD support, and what protocol versions are implemented?

The R5F64189PFD supports two independent CAN modules compliant with ISO 11898-1 (CAN 2.0B active). Each module provides full CAN 2.0B functionality including identifier masking, message filtering, and 32 configurable mailboxes. Both controllers operate concurrently and support bit rates up to 1 Mbps, enabling dual-network redundancy or segmentation in complex R5F64189PFD-based systems.

What is the maximum A/D conversion resolution and channel count supported by the R5F64189PFD?

The R5F64189PFD features a 10-bit successive-approximation A/D converter with up to 34 input channels. All channels include integrated sample-and-hold circuitry, enabling simultaneous sampling of multiple analog signals. Channel selection is software-configurable, and conversion results are accessible via memory-mapped registers or DMA transfer-critical for high-fidelity sensor monitoring in R5F64189PFD applications.

Is the R5F64189PFD pin-compatible with other members of the R32C/118 Group?

Yes, the R5F64189PFD is fully pin-compatible with all 144-pin LQFP variants in the R32C/118 Group, including R5F64185NFD, R5F64187DFD, and R5F64188PFD. Identical PLQP0144KA-A packaging, shared pin functions, and consistent electrical characteristics allow direct substitution within the same PCB footprint-enabling scalable memory and feature selection without layout revision for the R5F64189PFD and its siblings.
