FAQ

What is the maximum operating frequency of the R5F72374BDFP#V0?

The R5F72374BDFP#V0 operates at a maximum CPU frequency of 100 MHz, achieved via its on-chip PLL clock generator with external crystal input (4–20 MHz). This frequency enables 100 MIPS performance for real-time control tasks, and the R5F72374BDFP#V0 maintains timing compliance across its specified industrial temperature range (−40°C to +85°C) without derating.

Does the R5F72374BDFP#V0 include a CAN controller, and what version does it support?

Yes, the R5F72374BDFP#V0 integrates a single CAN controller compliant with ISO 11898-1:2003 (CAN 2.0B), supporting both standard (11-bit) and extended (29-bit) identifier frames, programmable bit timing, and hardware message filtering. The R5F72374BDFP#V0's CAN module operates independently of the CPU core, enabling zero-latency message reception and transmission scheduling.

What type of Flash memory is used in the R5F72374BDFP#V0, and does it include error correction?

The R5F72374BDFP#V0 uses 512 KB of on-chip Flash memory with built-in ECC (Error Correction Code) logic that detects and corrects single-bit errors in real time. This ECC implementation is active during normal program execution and erase/write cycles, ensuring firmware integrity in electrically noisy industrial environments - a key reliability feature of the R5F72374BDFP#V0.

Is the R5F72374BDFP#V0 pin-compatible with other members of the SH7237 Group?

Yes, the R5F72374BDFP#V0 shares identical pin assignment and electrical characteristics with other 144-pin LQFP variants in the SH7237 Group (e.g., R5F72373BDFP#V0, R5F72375BDFP#V0), enabling drop-in replacement within the same package footprint. The R5F72374BDFP#V0 maintains consistent signal routing, power pin placement, and peripheral pin mapping across this family.

What development tools are officially supported for the R5F72374BDFP#V0?

Renesas provides official support for the R5F72374BDFP#V0 through the CS+ (formerly High-performance Embedded Workshop) IDE, E1/E20 debug emulators, and the Renesas Starter Kit for SH7237. These tools enable full debugging, Flash programming, and peripheral register visualization - all validated for use with the R5F72374BDFP#V0 hardware configuration and memory map.
