Overview
R5F52305ADFM#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 128 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D converter (12 channels), and 2-channel 12-bit D/A converter. It integrates USB 2.0 full-speed host/function/OTG, CAN, SCI, I²C, RSPI, and capacitive touch sensing (10 channels), targeting industrial HMI and sensor-edge control applications.
For engineers reviewing the R5F52305ADFM#30 datasheet, R5F52305ADFM#30 pinout, R5F52305ADFM#30 application, or R5F52305ADFM#30 equivalent, this MCU delivers deterministic real-time performance with FPU, MPU, ELC event-driven operation, and IEC60730-compliant self-test functions for safety-critical embedded systems.
Technical Context
The R5F52305ADFM#30 belongs to the RX230 Group and uses the RXv2 CPU core with IEEE 754-compliant 32-bit single-precision FPU, 32-bit × 32-bit multiplier, and 32-bit divider (2-cycle min). It supports little- or big-endian data arrangement and features a 5-stage CISC Harvard pipeline with variable-length instructions.
Its clock system includes main (1–20 MHz), sub (32.768 kHz), and on-chip oscillators, with PLL-derived 54 MHz system clock (ICLK) and dedicated 48 MHz USB clock. Power management enables three low-power modes, LPT operation during software standby, and voltage detection across three independent LVD circuits.

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 |
|---|---|---|---|
| R5F52315ADFM#30 | Same RX230 Group, 128 KB flash, but adds 8 KB data flash and IEC60730 self-test functions not present in R5F52305ADFM#30 | Required where certified functional safety diagnostics (RAM test, A/D self-check) are mandatory | Select R5F52315ADFM#30 when data flash retention or IEC60730 Class B compliance is required; otherwise R5F52305ADFM#30 offers cost-optimized feature set |
| R5F52306ADFM#30 | Same package and pinout, but with 256 KB flash, 32 KB SRAM, and added USB 2.0 OTG (absent in R5F52305ADFM#30) | Suitable for USB-hosted firmware updates or peripheral bridging where R5F52305ADFM#30 lacks USB PHY | Choose R5F52306ADFM#30 if USB host capability or larger code space is needed; R5F52305ADFM#30 remains optimal for CAN-only edge nodes |
Compared with R5F52305ADFM#30, R5F52315ADFM#30 adds certified safety features at identical footprint, while R5F52306ADFM#30 expands memory and adds USB-but both require PCB-level validation due to functional differences despite shared 64-pin LFQFP packaging.

Does the R5F52305ADFM#30 include USB functionality?
No, the R5F52305ADFM#30 does not include USB functionality. According to the official Renesas datasheet R01DS0261EJ0120, USB 2.0 host/function/OTG is only available in RX231 Group devices and select RX230 variants like R5F52306ADFM#30. The R5F52305ADFM#30 omits the USB module entirely, making it suitable for CAN- or serial-centric designs where USB is unnecessary.
What analog peripherals are integrated into the R5F52305ADFM#30?
The R5F52305ADFM#30 integrates a 12-bit A/D converter (S12ADE) with 12 input channels and 0.83 µs conversion time, two 12-bit D/A converter (R12DAA) channels with 0.4 V to AVCC0 − 0.5 V output range, an on-chip temperature sensor (TEMPSA), and two comparator units (CMPBa). These peripherals support self-diagnostic functions and analog input disconnection detection-key for reliable operation in the R5F52305ADFM#30.
Which communication interfaces are supported by the R5F52305ADFM#30?
The R5F52305ADFM#30 supports CAN (1 channel, ISO11898-1, up to 1 Mbps), five SCI channels (asynchronous, clock-synchronous, smart card), one I²C bus interface (up to 400 kbps), one RSPI channel (up to 16 Mbps), and serial sound interface (SSI). It does not support USB or SD host interface-those are exclusive to higher-tier RX231 or expanded RX230 variants such as R5F52306ADFM#30.
What is the package type and pin count of the R5F52305ADFM#30?
The R5F52305ADFM#30 uses the PLQP0064KB-C package: a 64-pin low-profile quad flat package (LFQFP) with 10 × 10 mm body size, 0.5 mm pitch, and exposed thermal pad.
