FAQ

What is the maximum operating frequency and CPU performance of the R5F52317ADFM#10?

The R5F52317ADFM#10 operates at a maximum system clock frequency of 54 MHz, delivering 88.56 DMIPS performance using the RXv2 32-bit CPU core. Its 5-stage pipeline, variable-length instruction set, and on-chip FPU enable deterministic real-time execution for control loops and signal processing tasks. The R5F52317ADFM#10 achieves this performance with no wait states on SRAM and flash access up to 32 MHz.

Does the R5F52317ADFM#10 include CAN or SD host interface functionality?

No, the R5F52317ADFM#10 does not include CAN or SD host interface (SDHI) modules. As confirmed in Table 1.2 of the datasheet, these peripherals are disabled in the RX231 Group's 64-pin package variants, including the PLQP0064KB-C used by R5F52317ADFM#10. This distinguishes it from higher-pin-count versions like R5F52317BDLA#20 (100-pin TFLGA) which support both CAN and SDHI.

What security and safety features does the R5F52317ADFM#10 provide for certified applications?

The R5F52317ADFM#10 integrates TSIP-Lite for AES-128/256 encryption, true random number generation, and memory protection unit (MPU) enforcement. For functional safety, it provides hardware-assisted IEC 60730 compliance features including clock accuracy measurement circuit (CAC), independent watchdog timer (IWDT) disconnection detection, RAM test assistance via DOC, and ADC self-diagnostic functions - all directly supported in the R5F52317ADFM#10 silicon.

Which development tools and IDEs support the R5F52317ADFM#10?

The R5F52317ADFM#10 is fully supported by Renesas' E2 studio IDE (based on Eclipse), CS+ (formerly CubeSuite+), and the Renesas Flash Programmer. Debugging uses the FINE interface with compatible debug probes such as E2 Lite or E2 emulator. All toolchains provide direct register access, RTOS integration (FreeRTOS, CMSIS-RTOS), and IEC 60730 safety library support specific to the R5F52317ADFM#10 device configuration.

What is the operating temperature range and package type of the R5F52317ADFM#10?

The R5F52317ADFM#10 is rated for industrial operation from −40°C to +85°C (D version) and is supplied in a 64-pin LFQFP package (PLQP0064KB-C) measuring 10 × 10 mm with 0.5 mm pitch. This package includes an exposed thermal pad for enhanced heat dissipation and supports standard reflow soldering profiles per J-STD-020.
