It targets industrial HMI, smart sensor nodes, and connected appliance control where real-time performance, security, and mixed-signal integration are critical.
For engineers reviewing the R5F52318BGFL#30 datasheet, R5F52318BGFL#30 pinout, R5F52318BGFL#30 application, or R5F52318BGFL#30 equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-B (48-pin LFQFP, 7 × 7 mm, 0.5 mm pitch), functional validation for CAN, USB, and CTSU, and confirmed alternative options for migration or second sourcing.
Technical Context
The R5F52318BGFL#30 belongs to the RX231 Group and implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions. It supports little- or big-endian data arrangement, 32-bit × 32-bit multiply-accumulate, and single-cycle instruction execution at 54 MHz.
Its clock system includes main (1–20 MHz), sub-clock (32.768 kHz), on-chip high-/low-speed oscillators, PLL (4–12.5 MHz input), and USB-dedicated PLL (4/6/8/12 MHz). System clock (ICLK) runs at 54 MHz; peripheral clocks (PCLKA/B/D) are independently configurable up to 54 MHz, 32 MHz, or 54 MHz respectively for MTU2a, other peripherals, and S12AD.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52318AGFL#30 | Same package and peripherals, but D-version (−40 to +85°C) instead of G-version; lacks extended temperature qualification | Suitable for commercial indoor equipment without thermal stress; not qualified for under-hood or industrial enclosure use | Select R5F52318AGFL#30 only if ambient temperature remains ≤85°C and cost sensitivity outweighs long-term reliability margin. |
| R5F52308BGFL#30 | RX230 Group part: identical package and pinout, but reduced peripheral set-no CAN, no SDHI, no USB OTG, only 256 KB flash and 32 KB RAM | Fits simpler control tasks without fieldbus or mass storage; lower BOM cost where USB host or CAN diagnostics are unnecessary | Choose R5F52308BGFL#30 when application requires only basic USB device, SCI, and ADC functionality-avoid if CAN messaging or SD card logging is needed. |
Compared with R5F52318BGFL#30, R5F52318AGFL#30 trades extended temperature resilience for lower cost in benign environments, while R5F52308BGFL#30 reduces flash/RAM and removes CAN/SDHI to serve cost-constrained designs lacking those interfaces-neither is pin-compatible nor drop-in replaceable due to functional and qualification differences.
