Overview
R5F51111ADLF#U0 from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 32 KB on-chip flash, 10 KB SRAM, 8 KB data flash, 12-bit A/D converter (14 channels), USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial sensor nodes and low-power HMI control systems.
For engineers reviewing the R5F51111ADLF#U0 datasheet, R5F51111ADLF#U0 pinout, R5F51111ADLF#U0 application, or R5F51111ADLF#U0 equivalent, this page delivers verified package mapping (PWLG0064KA-A, 5×5 mm WFLGA), confirmed peripheral set (USBc, MTU2×6, RIIC, RSPI, SCI×3), real-time clock with calendar mode, and low-power software standby (0.44 μA, 4.8 μs wake-up).
Technical Context
The R5F51111ADLF#U0 implements a CISC Harvard architecture with five-stage pipeline, variable-length instructions, and on-chip debugging via FINE interface. It supports little-endian instruction/data layout and big-endian data selection, with 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations.
Its clock system integrates high-speed on-chip oscillator (32 MHz ±1% over −40 to +85°C), PLL (4–8 MHz input), sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), enabling independent ICLK/PCLK/FCLK domains and CAC-based frequency accuracy monitoring for IEC 60730 compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51111ADFM#3A | Same core, memory, and peripherals; differs only in package (PLQP0064KB-A, 10×10 mm LFQFP vs. 5×5 mm WFLGA) | Requires PCB redesign due to footprint and pitch mismatch; better thermal dissipation but larger area | Select when legacy layout reuse or hand-soldering feasibility is prioritized over size and cost |
| R5F51113ADLM#UA | 36-pin WFLGA variant with reduced I/O (20 pins), no D/A, only 7 ADC channels, no USB OTG or SCI12 | Limited peripheral count restricts use to simpler control tasks without USB or multi-protocol comms | Choose for space-constrained cost-sensitive applications where USB and full timer set are unnecessary |
Compared with R5F51111ADLF#U0, R5F51111ADFM#3A offers identical functionality in a larger, more manufacturable package, while R5F51113ADLM#UA trades USB, DAC, and timer resources for minimal footprint - making the R5F51111ADLF#U0 optimal for compact, feature-rich embedded control where WFLGA assembly is supported.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51111ADLF#U0?
The R5F51111ADLF#U0 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS performance. Its RX CPU core features a five-stage pipeline, 64-bit accumulator for single-cycle 32×32 multiply-accumulate, and variable-length instruction encoding. This performance level is sustained across its full 1.8–3.6 V supply range, with no wait states on flash or SRAM access at 32 MHz.
Does the R5F51111ADLF#U0 support USB device, host, and OTG functionality?
Yes, the R5F51111ADLF#U0 integrates a USB 2.0 host/function module (USBc) supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, isochronous transfers, and Battery Charging (BC) detection. It operates in device, host (with ≥32 KB ROM), and On-The-Go (OTG) configurations - all using the same on-chip transceiver and USB0_DP/USB0_DM pins.
What low-power modes are available on the R5F51111ADLF#U0, and what is the lowest current consumption?
The R5F51111ADLF#U0 supports three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode, it achieves 0.44 μA typical current consumption while retaining RAM and RTC operation. Wake-up occurs in 4.8 μs via RTC alarm, external interrupt, or ELC event - enabling ultra-low-energy operation in battery-powered applications.
Is the R5F51111ADLF#U0 pin-compatible with other RX111 Group MCUs?
No - the R5F51111ADLF#U0 uses the PWLG0064KA-A 64-pin WFLGA package (5×5 mm, 0.5 mm pitch), which is not pin-compatible with LFQFP (PLQP0064KB-A) or LQFP (PLQP0064GA-A) variants. Pin assignments differ across packages; Table 1.2 in the datasheet confirms peripheral channel counts (e.g., SCI, ADC) also vary by pin count, requiring design-specific validation.
What development tools and debug interfaces are supported for the R5F51111ADLF#U0?
The R5F51111ADLF#U0 supports on-chip debugging via the FINE interface using Renesas E1 emulator. It includes full JTAG/SWD-compatible debug circuitry, allowing real-time execution control, register/memory inspection, and flash programming. Renesas e2 studio IDE and CS+ toolchain provide integrated support for C/C++ development, peripheral configuration, and IEC 60730 safety library integration.
