FAQ

What is the maximum operating frequency of the R5F72375BDFP#V0 CPU core?

The R5F72375BDFP#V0 features the SH-2A 32-bit RISC core with a maximum operating frequency of 64 MHz. This speed is achieved using an on-chip PLL with external crystal input (e.g., 8 MHz × 8), and all timing specifications-including CAN bit rate accuracy and ADC sampling intervals-are validated at this frequency. The R5F72375BDFP#V0 maintains full peripheral functionality without throttling at 64 MHz.

Does the R5F72375BDFP#V0 support CAN FD or only classical CAN 2.0B?

The R5F72375BDFP#V0 integrates a classical CAN 2.0B controller compliant with ISO 11898-1:2003, supporting data rates up to 1 Mbps and 11-bit standard identifiers. It does not support CAN FD features such as flexible data-rate switching or extended data length. For CAN FD applications, designers must select a newer Renesas RA or RH850 family device. The R5F72375BDFP#V0 remains fully interoperable with legacy CAN networks used in industrial machinery and building systems.

What debug interfaces are available on the R5F72375BDFP#V0?

The R5F72375BDFP#V0 provides a full IEEE 1149.1 JTAG interface with TRST, TDI, TDO, TCK, and TMS pins for boundary scan testing and on-chip debugging. It supports real-time trace, hardware breakpoints, and register visibility via Renesas E2 studio and CS+ IDE. No SWD or cJTAG alternatives are implemented. The R5F72375BDFP#V0 does not include SWD pins or alternate debug protocols-JTAG is the sole supported debug path.

Is the R5F72375BDFP#V0 qualified for automotive applications?

No, the R5F72375BDFP#V0 is rated for industrial use (Standard quality grade) with operating temperature range −40°C to +85°C and is not AEC-Q100 qualified. It lacks automotive-specific features such as enhanced ESD immunity, extended temperature screening, or failure-in-time (FIT) reporting. For automotive body control or chassis applications, Renesas recommends RH850/F1L or RL78/F14 devices. The R5F72375BDFP#V0 is intended for industrial automation, not safety-critical vehicle systems.

How many ADC channels does the R5F72375BDFP#V0 support, and what is their resolution?

The R5F72375BDFP#V0 includes a 12-channel, 10-bit successive approximation register (SAR) ADC with sample-and-hold capability. All channels are single-ended by default but can be configured for pseudo-differential operation using adjacent pairs. Conversion time is 1.2 μs per sample, and the module supports hardware-triggered sequences synchronized to timer events. The R5F72375BDFP#V0 ADC does not support 12-bit or higher resolution modes-10-bit is fixed and verified across the full temperature range.
