FAQ

What is the maximum operating frequency of the R5F72147GDFP#V1?

The R5F72147GDFP#V1 operates at a maximum CPU frequency of 100 MHz using the SH-2A core. This frequency is achieved when the internal PLL is configured with an appropriate input clock source-such as a 10 MHz crystal-and the FRQCR register settings enable the target multiplication ratio. The R5F72147GDFP#V1 maintains timing compliance across its specified industrial temperature range (−40°C to +85°C) at this speed.

Does the R5F72147GDFP#V1 include built-in Flash memory with error correction?

Yes, the R5F72147GDFP#V1 integrates 512 KB of on-chip Flash memory with hardware-based ECC (Error Correction Code) support. This implementation provides single-bit error correction and double-bit error detection across the entire Flash array, enhancing data integrity for firmware storage and enabling compliance with functional safety standards such as IEC 61508 SIL-2 in relevant configurations.

Can the R5F72147GDFP#V1 operate in standalone mode without external memory?

Yes, the R5F72147GDFP#V1 supports Single Chip Mode (Mode 3), allowing full operation using only its internal 512 KB Flash and 64 KB RAM. In this mode, all address and data bus pins are repurposed as general-purpose I/O, eliminating the need for external memory components and simplifying PCB layout for compact embedded designs.

What communication interfaces are integrated into the R5F72147GDFP#V1?

The R5F72147GDFP#V1 integrates multiple communication peripherals: three SCI modules (supporting UART, IrDA, and LIN), one I²C bus interface, one CAN 2.0B controller with 32 message objects, and a full-speed USB 2.0 transceiver. These interfaces enable flexible connectivity in mixed-protocol systems such as industrial gateways or automotive ECUs where CAN, serial, and USB coexist.

Is the R5F72147GDFP#V1 qualified for automotive applications?

The R5F72147GDFP#V1 is rated for industrial temperature (−40°C to +85°C) and classified as a "Standard" quality grade device per Renesas documentation. While it includes CAN 2.0B and robust EMI features suitable for automotive body electronics, it is not AEC-Q100 qualified and lacks the extended temperature range or qualification documentation required for powertrain or safety-critical automotive functions.
