FAQ

What is the maximum operating frequency and CPU performance of the R5F56317DDFC#V0?

The R5F56317DDFC#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of computational performance using the 32-bit RX CPU core. Its single-precision IEEE-754 floating-point unit (FPU) and dual multiply-accumulate units enable efficient signal processing and control algorithm execution. This performance level is confirmed in Renesas document R01DS0098EJ0180, page 1.

Does the R5F56317DDFC#V0 include an Ethernet MAC, and what interface standards does it support?

Yes, the R5F56317DDFC#V0 includes a fully integrated Ethernet MAC supporting both MII and RMII physical layer interfaces per IEEE 802.3u, with 10/100 Mbps operation, full/half-duplex modes, and flow control (IEEE 802.3x). It also features a dedicated EDMAC for descriptor-based DMA transfers, reducing CPU overhead. This distinguishes it from RX631 Group parts, which lack Ethernet functionality.

What memory resources are available on the R5F56317DDFC#V0?

The R5F56317DDFC#V0 integrates 1.5 MB of on-chip flash memory (with zero wait states at 100 MHz), 192 KB of SRAM, and 32 KB of reprogrammable data flash rated for 100,000 write/erase cycles. Flash programming supports both on-board and off-board (parallel programmer) methods. These values are specified in Table 1.1 of R01DS0098EJ0180, page 2.

Which analog peripherals are integrated into the R5F56317DDFC#V0?

The R5F56317DDFC#V0 integrates a 21-channel 12-bit A/D converter (S12ADa) with 1.0 µs conversion time, an 8-channel 10-bit A/D converter (ADb), two 10-bit D/A converters (DAa), and an on-die temperature sensor with ±1°C accuracy. All ADCs include sample-and-hold circuits and support software, timer, or external trigger initiation - critical for precision industrial sensing applications.

What security and safety features does the R5F56317DDFC#V0 provide for industrial applications?

The R5F56317DDFC#V0 includes a Data Encryption Unit (DEU) supporting AES-128/192/256 in ECB/CBC modes, CRC calculation hardware, independent watchdog timer (IWDT) with dedicated oscillator, oscillation-stop detection, and self-diagnostic functions for the A/D converter - all aligned with IEC 60730 Class B requirements. These features are documented in the "Useful functions for IEC60730 compliance" section of R01DS0098EJ0180, page 1.
