Product details
Overview
R5F52306ADFM#10 from Renesas is a 32-bit RXv2 core MCU operating at up to 54 MHz (88.56 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, and integrated 12-bit A/D (24 channels) and D/A (2 channels) converters. It supports USB 2.0 full-speed device mode, CAN, SCI, I²C, SPI, capacitive touch sensing (24 keys), RTC, FPU, and TSIP-Lite encryption - deployed in industrial HMI and sensor gateway applications.
For engineers reviewing the R5F52306ADFM#10 datasheet, R5F52306ADFM#10 pinout, R5F52306ADFM#10 application, or R5F52306ADFM#10 equivalent, key selection criteria include its 64-pin LFQFP package, absence of SDHI and CAN modules (per Table 1.3), D-version −40 to +85°C rating, and verified support for USB device-only operation without host/OTG capability.
Technical Context
The R5F52306ADFM#10 belongs to the RX230 Group and implements the RXv2 CPU core with IEEE 754-compliant 32-bit single-precision FPU, 32×32-bit multiplier, and 32-bit divider (2-cycle min). Its clock system includes main (1–20 MHz), sub (32.768 kHz), and on-chip oscillators, with PLL enabling 54 MHz ICLK and 48 MHz USB clock generation.
Peripheral integration follows RX230 Group constraints: it includes 6-channel TPU, 6-channel MTU2, 4-channel DMAC, ELC, MPC, and CTSU (24-channel self-capacitance), but excludes SDHI and CAN modules per product table confirmation. Real-time capabilities are supported by RTC (calendar mode), LPT (sub-clock driven), and IWDT (dedicated low-speed oscillator).

Applications
| Industrial HMI Panel | Smart Sensor Gateway |
|---|---|
Use Scenario: Touch-enabled local operator interface for PLC-controlled machinery with real-time status display and parameter adjustment. IC Role / Device Role / Timing Role: Main controller executing GUI rendering, capacitive touch scanning (24 keys), USB device communication with PC configuration tool, and RTC-based event logging. Use Value: Integrated CTSU and USB eliminate external touch controller and USB PHY, reducing BOM count and PCB area while maintaining deterministic 54 MHz real-time response. | Use Scenario: Edge node aggregating data from multiple analog sensors (temperature, pressure, humidity) and transmitting via USB to central monitoring PC. IC Role / Device Role / Timing Role: Signal acquisition hub using 24-channel 12-bit ADC with per-channel sampling time control, 2-channel DAC for calibration reference, and USB full-speed bulk transfer. Use Value: On-chip 256 KB flash stores sensor firmware and calibration tables; 8 KB data flash retains field-updated coefficients with 1M endurance for long-term deployment. |
| USB Peripheral Device | IEC 60730-Class B Appliance Controller |
Use Scenario: Firmware-upgradable USB HID device (e.g., programmable knob panel or diagnostic dongle) requiring secure firmware integrity verification. IC Role / Device Role / Timing Role: USB device controller with descriptor handling, TSIP-Lite AES-GCM for encrypted firmware image validation, and FPU-assisted signal preprocessing before transmission. Use Value: Hardware-accelerated cryptographic engine prevents unauthorized firmware loading; USB device-only mode simplifies compliance testing versus OTG/host implementations. | Use Scenario: Safety-critical white goods controller (e.g., washing machine main board) requiring self-test and fault detection per IEC 60730 Class B. IC Role / Device Role / Timing Role: System manager executing RAM test assistance (DOC), ADC self-diagnostic, clock accuracy measurement (CAC), and IWDT supervision with fail-safe shutdown.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52305ADFM#30 | 128 KB flash, 32 KB RAM, same package and peripheral set (no SDHI/CAN), identical D-temp grade | Lower memory capacity limits firmware complexity and OTA update partitioning | Select when application firmware fits within 128 KB and cost optimization is prioritized over future scalability |
| R5F52316ADFM#30 | 256 KB flash, 32 KB RAM, adds SDHI interface and CAN module; otherwise identical pinout and clock/peripheral specs | Enables local SD card logging and CAN bus integration in industrial networks | Choose when SDHI or CAN connectivity is required - same PCB layout but higher BOM cost and qualification effort |
Compared with R5F52306ADFM#10, R5F52305ADFM#30 offers reduced flash for cost-sensitive deployments, while R5F52316ADFM#30 extends functionality with SDHI and CAN - both share identical 64-pin LFQFP packaging and −40 to +85°C rating but differ in memory mapping and peripheral enablement.

FAQ
Does R5F52306ADFM#10 support USB host or OTG functionality?
No, R5F52306ADFM#10 supports USB 2.0 full-speed device mode only (12 Mbps), as confirmed in Table 1.3 and datasheet Section 1.1. It lacks USB host controller logic and OTG negotiation circuitry. For host/OTG capability, consider RX231 Group variants like R5F52318ADFM#30, which explicitly list USB host/function/OTG support.
What is the maximum ADC sampling rate achievable with R5F52306ADFM#10?
R5F52306ADFM#10 achieves a minimum conversion time of 0.83 µs per channel when ADCLK runs at 54 MHz, enabling up to 1.2 MSps aggregate throughput across its 24-channel 12-bit S12ADE ADC. Channel sequencing and group scan modes allow configurable sampling intervals, but individual channel rate is bounded by this 0.83 µs specification.
Is CAN interface available on R5F52306ADFM#10?
No, R5F52306ADFM#10 does not include the CAN module (RSCAN). Table 1.3 explicitly marks CAN as "Not available" for all RX230 Group parts including R5F52306ADFM#10. CAN support begins with RX231 Group members such as R5F52316ADFM#30 and above.
What debug interface does R5F52306ADFM#10 use, and is JTAG supported?
R5F52306ADFM#10 uses the FINE (Fast In-circuit Non-intrusive Emulation) interface for debugging and programming, as stated in datasheet Section 1.1. It does not support standard JTAG; FINE operates over a 2-pin interface (F_IN/F_OUT) and is compatible with Renesas E2 studio and CS+ IDE with appropriate debug probes like E2 Lite.
Can R5F52306ADFM#10 operate from a 3.3 V supply, and what are the implications for I/O voltage tolerance?
Yes, R5F52306ADFM#10 operates from 1.8 V to 5.5 V, so 3.3 V is fully supported. Its general I/O ports include 5-V-tolerant pins (5 pins total per Table 1.2), allowing direct interfacing with 5 V logic without level shifters - critical for legacy industrial sensor or actuator interfaces.
