FAQ

What is the maximum operating frequency of the R5F72147GDFA#V1?

The R5F72147GDFA#V1 operates at a maximum CPU frequency of 64 MHz, achieved via its on-chip clock pulse generator (CPG) with PLL-based frequency multiplication. This clock speed is sustained across the full −40°C to +105°C operating temperature range and supports deterministic real-time execution for time-critical automotive functions. The R5F72147GDFA#V1 achieves this performance while maintaining compatibility with standard 3.3 V power supplies and low-power design practices.

Does the R5F72147GDFA#V1 support CAN FD?

No, the R5F72147GDFA#V1 supports only CAN 2.0B protocol with bit rates up to 1 Mbps. It does not implement CAN FD features such as flexible data-length payloads or higher arbitration-phase speeds. For CAN FD capability, Renesas offers the R5F72148GDFA#V1 variant within the same SH7214 family. The R5F72147GDFA#V1 remains fully compatible with legacy CAN networks used in body control and comfort systems where FD bandwidth is not required.

Is the R5F72147GDFA#V1 qualified for automotive use?

Yes, the R5F72147GDFA#V1 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C), confirming its suitability for automotive body electronics and chassis applications. It meets stringent reliability, ESD, and thermal cycling requirements defined by the Automotive Electronics Council. The R5F72147GDFA#V1 also supports functional safety development per ISO 26262 ASIL-B through built-in self-test features, lock-step peripherals, and failure reporting mechanisms documented in Renesas' safety manual.

What debug interface does the R5F72147GDFA#V1 provide?

The R5F72147GDFA#V1 includes a full IEEE 1149.1-compliant JTAG interface supporting real-time debugging, flash programming, boundary scan testing, and trace data capture. This interface is accessible via standard 14-pin JTAG header and integrates with Renesas' E2 studio IDE and third-party tools like Lauterbach TRACE32. The R5F72147GDFA#V1's debug architecture allows non-intrusive breakpoint insertion and register visibility without disrupting real-time operation.

How much user-accessible Flash memory does the R5F72147GDFA#V1 have?

The R5F72147GDFA#V1 provides 512 KB of on-chip Flash memory, all user-accessible for application code and data storage. This includes support for in-application programming (IAP), sector erase (minimum 1 KB), and 100,000 write/erase cycles per sector. The R5F72147GDFA#V1's Flash controller implements error correction (ECC) and read-while-write capability, enabling seamless firmware updates without halting real-time tasks.
