Overview

R5F51136ADFM#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, 17-channel 12-bit A/D converter, dual 12-bit D/A converters, LCD controller/driver (40×4 segments), capacitive touch sensing (12 channels), RTC, and low-power software standby mode (0.44 µA). It targets embedded human-interface applications such as smart meters and industrial HMI panels.

For engineers reviewing the R5F51136ADFM#30 datasheet, R5F51136ADFM#30 pinout, R5F51136ADFM#30 application, or R5F51136ADFM#30 equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-A (64-pin LFQFP), validated pin functions, real-world use cases, and two confirmed alternative parts with documented technical and application differences.

Technical Context

The R5F51136ADFM#30 implements the RXv1 CISC Harvard architecture with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), all managed via configurable ICLK/PCLK/FCLK domains.

Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module-to-module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers triggered by 44 event sources. The MCU supports IEC 60730 safety compliance via CAC, IWDT, and RAM test assist functions.

FAQ

What is the maximum operating frequency and associated performance of the R5F51136ADFM#30?

The R5F51136ADFM#30 operates at a maximum frequency of 32 MHz, delivering 50 DMIPS (Dhrystone MIPS) performance. This is achieved using the 32-bit RX CPU core with five-stage pipeline and ultra-compact instruction set. Performance is sustained across the full 1.8–3.6 V supply range, with frequency scaling tied to voltage: 32 MHz is guaranteed only at 2.7–3.6 V. The R5F51136ADFM#30 maintains this speed with zero wait states on both flash and SRAM accesses.

Does the R5F51136ADFM#30 support capacitive touch sensing?

No, the R5F51136ADFM#30 does not support capacitive touch sensing. Although the RX113 Group datasheet lists CTSU functionality, Table 1.2 explicitly confirms CTSU is only available in the 100-pin package variants (e.g., R5F51136ADFP#3A). The R5F51136ADFM#30 uses the 64-pin LFQFP (PLQP0064KB-A) package, which omits the TS0–TS11 pins and associated internal circuitry required for CTSU operation.

What USB capabilities does the R5F51136ADFM#30 provide?

The R5F51136ADFM#30 integrates a full-featured USB 2.0 host/function/OTG module compliant with USB 2.0 specification. It supports full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, isochronous transfers, Battery Charging (BC) 1.2 detection, and On-The-Go (OTG) negotiation. The on-chip transceiver eliminates external PHY requirements, and USB0_DP/USB0_DM pins are routed for direct connection to the USB connector with appropriate series termination and ESD protection.

What are the memory resources available on the R5F51136ADFM#30?

The R5F51136ADFM#30 includes 256 KB of on-chip flash memory for program code (zero wait states at 32 MHz), 32 KB of SRAM for runtime data, and 8 KB of data flash for nonvolatile parameter storage. The data flash supports 1,000,000 erase/write cycles and enables background operation (BGO), allowing concurrent code execution and data logging. All memory blocks are accessible over the internal bus without external glue logic.

Which package type and pin count does the R5F51136ADFM#30 use?

The R5F51136ADFM#30 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 package provides 46 general-purpose I/O pins, 1 input-only pin, 41 pull-up resistor options, 34 open-drain outputs, and 4 5-V-tolerant inputs. Pin assignments match the RX113 Group's 64-pin variant defined in Figure 1.4 and Table 1.5 of the official datasheet R01DS0216EJ0120.
