Product details
Overview
R5F51305AGFL#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 12-bit A/D converter (17 channels), dual 8-bit D/A outputs, capacitive touch sensing (24 keys), and IEC60730-compliant safety functions - deployed in industrial human-machine interfaces and appliance control systems.
For engineers reviewing the R5F51305AGFL#30 datasheet, R5F51305AGFL#30 pinout, R5F51305AGFL#30 application, or R5F51305AGFL#30 equivalent, this page delivers verified package mapping (PLQP0048KB-B, 48-pin LFQFP), validated peripheral configuration (SCIg ×3, RIIC ×1, RSPI ×1, MTU2 ×6), confirmed low-power modes (software standby @ 0.37 µA), and real-world timing roles including RTC calendar mode and ELC-triggered sensor acquisition.
Technical Context
The R5F51305AGFL#30 implements a CISC Harvard-architecture RX core with 5-stage pipeline, 32-bit × 32-bit multiplier (1-cycle), 64-bit accumulator, and variable-length instructions. It integrates an Event Link Controller (ELC) enabling interrupt-free inter-module triggering - e.g., MTU2 PWM events initiating A/D conversion without CPU wake-up.
Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL (4–8 MHz input), and dedicated IWDT oscillator (15 kHz). Power management supports three low-power modes, with software standby recovery in 4.8 µs and supply current of 96 µA/MHz in high-speed operation.

| Low-Power Timer (LPT) | 16-bit timer running on sub-clock or IWDTCLK during software standby - enables periodic wake-up every 2–65 sec for battery-powered status checks. |
| Background Operation (BGO) | Data flash programming/erasing while CPU executes code - permits seamless firmware patching and logging without system interruption. |
| Multi-Function Pin Controller (MPC) | Per-pin function selection (GPIO, SCI, CTSU, etc.) - simplifies PCB layout reuse across variants and enables dynamic peripheral remapping in runtime. |
Applications
| Industrial HMI Panel | Smart Appliance Control |
|---|---|
|
Use Scenario: 4.3-inch resistive/touchscreen HMI with LED backlight, rotary encoder, and status LEDs. IC Role / Device Role / Timing Role: Main controller executing GUI logic, driving SPI display, scanning capacitive keys, and managing real-time alarm timers. Use Value: Integrated CTSU (24 keys) and RSPI (16 Mbps) eliminate external touch controller and display driver ICs; RTC calendar mode enables scheduled maintenance alerts. |
Use Scenario: Washing machine main board handling motor phase control, water level sensing, temperature monitoring, and user interface. IC Role / Device Role / Timing Role: System-on-chip managing PWM-driven triac/motor drivers, A/D readings from NTC thermistors, and I²C communication with display module. Use Value: Dual 8-bit DACs generate precise reference voltages for analog comparators; 17-channel A/D acquires multiple sensor inputs simultaneously with 1.4 µs resolution. |
| Energy Meter Interface | Factory Automation Sensor Node |
|
Use Scenario: DIN-rail mounted meter with pulse input (kWh), LCD display, IR/RS-485 comms, and tamper detection. IC Role / Device Role / Timing Role: Data concentrator acquiring pulse counts via TMR capture, updating LCD via SCI, and transmitting via RIIC or SCIg to gateway. Use Value: Hardware CRC calculator ensures secure firmware OTA updates; LVD circuits (3 voltage levels) detect brown-out conditions before meter data corruption occurs. |
Use Scenario: IP65-rated wireless sensor node monitoring vibration, temperature, and humidity in CNC machine enclosures. IC Role / Device Role / Timing Role: Edge-processing node performing FFT preprocessing on accelerometer data, storing logs in data flash, and waking periodically to transmit via RSPI to LoRa module. Use Value: Software standby @ 0.37 µA extends 2×AA battery life beyond 5 years; ELC-linked MTU2 triggers A/D sampling only on mechanical event detection - minimizing active time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51305ADFL#30 | Same core, memory, and peripherals; rated for –40°C to +85°C (D-grade) instead of +105°C (G-grade). | Suitable for indoor consumer appliances but not under-hood automotive or high-temp industrial enclosures. | Select when ambient temperature stays below 85°C and cost sensitivity outweighs extended thermal margin. |
| R5F51306BGFL#30 | 256 KB flash, 32 KB SRAM, same package and peripheral set - no change in pinout or clock architecture. | Required for larger firmware images (e.g., BLE stack + OTA bootloader + application) where 128 KB is insufficient. | Choose when future firmware growth or feature expansion (e.g., additional communication protocols) demands more code space. |
Compared with R5F51305AGFL#30, the D-grade variant trades thermal range for lower unit cost, while the 256 KB variant retains identical I/O and timing behavior but doubles flash headroom - both alternatives maintain full pin and software compatibility within the RX130 Group.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51305AGFL#30?
The R5F51305AGFL#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its RX CPU core features a 5-stage pipeline, 32-bit × 32-bit multiplication in one cycle, and a 64-bit accumulator - enabling deterministic execution of real-time control algorithms and UI rendering tasks without external co-processors. This performance level is sustained across its full 1.8–5.5 V supply range.
Does the R5F51305AGFL#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F51305AGFL#30 includes hardware-assisted IEC60730 Class B compliance features: RAM test assistance via DOC, A/D converter self-diagnostic and disconnection detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated oscillator, and voltage monitoring circuits with configurable thresholds. These reduce software overhead and external component requirements for safety-critical appliance and industrial control applications.
What package type and pin count does the R5F51305AGFL#30 use?
The R5F51305AGFL#30 uses the PLQP0048KB-B package: a 48-pin Low-Profile Quad Flat Package measuring 7 mm × 7 mm with 0.5 mm pitch. This RoHS-compliant, lead-free package supports reflow soldering and provides 38 general-purpose I/O pins, including 24 dedicated CTSU touch channels and 17 A/D inputs - optimized for space-constrained industrial and consumer control boards.
Can the R5F51305AGFL#30 operate from a single 3.3 V supply in high-speed mode?
Yes, the R5F51305AGFL#30 supports 3.3 V operation at its full 32 MHz speed. Its supply voltage range is 1.8 V to 5.5 V, with guaranteed 32 MHz operation when VCC ≥ 2.7 V. At 3.3 V, it draws 96 µA/MHz in high-speed mode and achieves 4.8 µs wake-up from software standby - making it ideal for mixed-voltage systems where 3.3 V is the primary rail for logic and peripherals.
How many communication interfaces does the R5F51305AGFL#30 include, and what are their key capabilities?
The R5F51305AGFL#30 includes three SCIg channels (asynchronous/clock-sync/Smart Card), one RIIC channel (I²C/SMBus, up to 400 kbps), and one RSPI channel (SPI master/slave, up to 16 Mbps). Each SCIg channel supports hardware flow control (CTS#/RTS#), while RIIC and RSPI provide open-drain and configurable frame lengths (8–32 bits) - enabling concurrent connectivity to displays, sensors, and wireless modules without protocol translation ICs.
