For engineers reviewing the R5F52317ADFM#30 datasheet, R5F52317ADFM#30 pinout, R5F52317ADFM#30 application, or R5F52317ADFM#30 equivalent, key selection criteria include its 64-pin LFQFP (10 × 10 mm) package, −40 to +85°C temperature grade, absence of SDHI and CAN modules (per Table 1.2), and compatibility with Renesas' e2 studio and CS+ toolchains for safety-critical IEC 60730-compliant designs.

Technical Context

The R5F52317ADFM#30 belongs to the RX231 Group and implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions. It integrates memory protection unit (MPU), on-chip debugging (FINE interface), and event link controller (ELC) enabling interrupt-free peripheral coordination during CPU sleep.

Its clock system includes main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), and USB-dedicated PLL supporting 48 MHz USB clock generation. Power management features three low-power modes, LPT timer active in software standby, and voltage detection circuits with configurable thresholds.

FAQ

What is the maximum operating frequency and core type of the R5F52317ADFM#30?

The R5F52317ADFM#30 operates at a maximum frequency of 54 MHz using the 32-bit RXv2 CPU core, delivering 88.56 DMIPS performance. Its architecture includes a 5-stage pipeline, variable-length instructions, and hardware floating-point unit compliant with IEEE 754 single-precision standard - enabling efficient execution of real-time control algorithms and signal processing tasks within the R5F52317ADFM#30.

Does the R5F52317ADFM#30 support CAN or SD host interface?

No, the R5F52317ADFM#30 does not integrate CAN or SD host interface (SDHI) modules. As confirmed in Table 1.2 of the datasheet, these peripherals are excluded from the 64-pin RX231 variants including R5F52317ADFM#30. Designers requiring CAN must select RX230 Group parts (e.g., R5F52306ADFM#30) or upgrade to 100-pin RX231 packages like R5F52317ADLA#20, which do support CAN and SDHI.

What memory resources are available on the R5F52317ADFM#30?

The R5F52317ADFM#30 includes 384 KB of on-chip flash memory (with no-wait access up to 32 MHz), 32 KB of SRAM (no-wait at 54 MHz), and 8 KB of data flash rated for 1,000,000 program/erase cycles. This memory configuration supports robust firmware storage, real-time data buffering, and field-upgradable parameters - all integral to the R5F52317ADFM#30's role in long-lifecycle industrial applications.

Is the R5F52317ADFM#30 qualified for extended temperature operation?

The R5F52317ADFM#30 is rated for −40 to +85°C (D-grade), not extended temperature. For operation up to +105°C, the functionally identical R5F52317AGFM#30 (G-grade) is available. Both share identical pinout, peripherals, and electrical characteristics except thermal specification - making R5F52317AGFM#30 a drop-in replacement where ambient conditions exceed 85°C, as verified in Renesas' product tables.

What debugging interfaces does the R5F52317ADFM#30 support?

The R5F52317ADFM#30 supports the FINE (Flash Independent Non-intrusive Emulator) interface for on-chip debugging, enabling breakpoints, watchpoints, and real-time trace without halting CPU execution. It is compatible with Renesas' E2 emulator and IDEs including e2 studio and CS+, providing full visibility into the R5F52317ADFM#30's runtime behavior during development and validation phases.
