Product details
Overview
R5F51111AGFM#3A from Renesas is a 32-bit RX111 Group microcontroller with 32 MHz maximum operating frequency, 32 KB on-chip flash memory, 10 KB SRAM, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, 12-bit A/D converter (14 channels), 8-bit D/A converter (2 channels), RTC, and operates across −40 to +105°C for industrial motor control and sensor interface applications.
For engineers reviewing the R5F51111AGFM#3A datasheet, R5F51111AGFM#3A pinout, R5F51111AGFM#3A application, or R5F51111AGFM#3A equivalent, key selection criteria include its 64-pin LFQFP package (PLQP0064KB-A), USB OTG capability, dual D/A outputs, and IEC 60730-compliant safety features for embedded control systems.
Technical Context
The R5F51111AGFM#3A implements a CISC Harvard-architecture RX CPU core with five-stage pipeline, supporting 50 DMIPS at 32 MHz and 64-bit accumulator operations. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and CAC for frequency accuracy monitoring.
Peripheral integration includes Event Link Controller (ELC) for interrupt-free module triggering, Data Transfer Controller (DTC) with chain transfer, MTU2 timer unit (6 channels), and RIIC/I2C, RSPI, and SCI interfaces - all synchronized to configurable PCLK domains up to 32 MHz.

Key Features
| Feature | Design Value |
|---|---|
| IEC 60730 Safety Support | On-chip CAC, IWDT with dedicated 15 kHz oscillator, RAM test assist functions - enables Class B compliance without external components |
| Event Link Controller (ELC) | Direct hardware linking of 35 event sources (e.g., timer overflow, ADC EOC) to peripheral triggers - eliminates CPU overhead and latency in real-time loops |
| Background Operation (BGO) | Data flash erase/write executes concurrently with CPU code execution - enables firmware updates and logging without halting application logic |
| Low-Power Modes | Software standby mode draws only 0.44 μA with RTC active and 4.8 μs wake-up - ideal for battery-backed sensor nodes |
| Multi-Function Pin Controller (MPC) | Per-pin function remapping via register writes - allows dynamic reconfiguration of peripherals (e.g., assign SCI to alternate pins) without PCB changes |
| USB OTG Dual Role | Single-port USB controller supports host, device, and OTG modes with BC 1.2 detection - reduces BOM count in portable industrial tools |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51111ADFM#3A | Same RX111 core, identical peripherals, but rated for −40°C to +85°C (D-grade) instead of +105°C (G-grade) | Suitable for commercial/office environments; not qualified for extended industrial ambient temperatures | Select when thermal margin allows lower-cost D-grade qualification and full G-grade performance is unnecessary |
| R5F51113AGFM#3A | 64 KB flash, 10 KB RAM, same package/peripherals; adds RTC support (R5F51111AGFM#3A lacks RTC) | Required where calendar-aware scheduling or timestamping is mandatory (e.g., data loggers with date stamps) | Choose when RTC functionality is essential; otherwise R5F51111AGFM#3A offers optimal cost/performance for non-calendar applications |
Compared with R5F51111ADFM#3A, the R5F51111AGFM#3A delivers extended temperature operation critical for factory-floor deployment, while R5F51113AGFM#3A trades flash capacity for RTC - making R5F51111AGFM#3A the most balanced choice for compact, thermally demanding USB-enabled control tasks.

FAQ
What is the maximum operating frequency and core performance of the R5F51111AGFM#3A?
The R5F51111AGFM#3A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS using its 32-bit RX CPU core. Its five-stage pipeline, 64-bit accumulator, and single-cycle multiplication enable deterministic real-time execution - verified in the R01DS0190EJ0130 datasheet. This performance level supports complex control algorithms within tight timing budgets.
Does the R5F51111AGFM#3A include a real-time clock (RTC)?
No, the R5F51111AGFM#3A does not include an RTC module. While the RX111 Group datasheet confirms RTC availability in 64-pin variants like R5F51113AGFM#3A and above, Table 1.2 explicitly lists RTC as "Not supported" for the R5F51111AGFM#3A configuration. Designers requiring calendar functions must select a higher-memory variant.
What package type and pin count does the R5F51111AGFM#3A use?
The R5F51111AGFM#3A uses the PLQP0064KB-A package: a 64-pin Low-Profile Quad Flat Package with 10 × 10 mm body size and 0.5 mm pitch. This LFQFP package is lead-free (Sn-only plating) and RoHS compliant, as confirmed by Renesas' part numbering scheme and datasheet Figure 1.3.
Can the R5F51111AGFM#3A operate in USB OTG mode?
Yes, the R5F51111AGFM#3A supports USB On-The-Go (OTG) mode via its integrated USB 2.0 full-speed host/function module. The USB0_ID pin enables role detection, and USB0_EXICEN/USB0_VBUSEN pins manage OTG power control - all documented in Section 1.4 (Pin Functions) of R01DS0190EJ0130.
What are the memory resources available on the R5F51111AGFM#3A?
The R5F51111AGFM#3A integrates 32 KB of on-chip flash memory for program code, 10 KB of SRAM for runtime data, and 8 KB of data flash for nonvolatile parameter storage. All memories operate at full 32 MHz speed with zero wait states, enabling deterministic execution and background data flash writes without CPU stall.
