Product details
Overview
R5F51138ADFM#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 512 Kbytes of on-chip flash, 64 Kbytes of SRAM, and 8 Kbytes of 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), capacitive touch sensing unit (CTSU), RTC, and low-power software standby mode (0.44 µA). It targets embedded human-interface and sensor-fused industrial control applications.
For engineers reviewing the R5F51138ADFM#30 datasheet, R5F51138ADFM#30 pinout, R5F51138ADFM#30 application, or R5F51138ADFM#30 equivalent, this page delivers verified technical context, package-specific pin mapping for the 64-pin LFQFP (PLQP0064KB-A), real-world use cases in USB-connected HMI and low-power sensor nodes, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The R5F51138ADFM#30 implements the RXv1 CPU core with CISC Harvard architecture, five-stage pipeline, and variable-length instructions enabling ultra-compact code. Its clock system includes a high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), all managed via independent 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 four transfer modes with interrupt-source-specific configuration. The MCU supports IEC 60730 safety compliance via CAC, IWDT, and RAM test assist functions.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51138ADFM#30?
The R5F51138ADFM#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. This is achieved by the 32-bit RXv1 CPU core with five-stage pipeline and single-cycle instruction execution. The R5F51138ADFM#30 maintains this speed across its full 1.8–3.6 V supply range, with no wait states on flash or SRAM access, enabling deterministic real-time response in motor control and USB isochronous applications.
Does the R5F51138ADFM#30 support USB device, host, and OTG functionality?
Yes, the R5F51138ADFM#30 integrates a full-featured USB 2.0 module supporting device, host, and On-The-Go (OTG) modes at full-speed (12 Mbps) and low-speed (1.5 Mbps). It includes an on-chip transceiver, BC 1.2 battery charger detection, and isochronous transfer capability. The R5F51138ADFM#30 requires only external 27 Ω series resistors and a 1.5 kΩ pull-up on USB0_DP to meet USB-IF electrical compliance.
What are the key low-power capabilities of the R5F51138ADFM#30?
The R5F51138ADFM#30 offers three low-power modes, with software standby consuming just 0.44 µA while keeping the RTC and low-power timer (LPT) active. Recovery time from software standby is 4.8 µs. Its high-speed operating mode draws 0.11 mA/MHz, and it supports dynamic voltage/frequency scaling across high/middle/low-speed operating modes. These features make the R5F51138ADFM#30 suitable for battery-powered applications requiring multi-year operation.
How many analog-to-digital and digital-to-analog channels does the R5F51138ADFM#30 include?
The R5F51138ADFM#30 integrates a 17-channel 12-bit successive approximation register (SAR) A/D converter with 1.0 µs minimum conversion time and double-trigger function for motor control. It also includes two independent 12-bit D/A converters (DA0 and DA1) with output voltage range of 0.35 V to AVCC − 0.47 V. These analog resources are fully accessible in the 64-pin LFQFP package and supported by dedicated reference pins (VREFH0/VREFL0, VREFH/VREFL).
Is the R5F51138ADFM#30 pin-compatible with other members of the RX113 Group?
No, the R5F51138ADFM#30 is not pin-compatible with 100-pin RX113 variants like R5F51138ADFP#30 due to differing package footprints (64-pin LFQFP vs. 100-pin LFQFP) and reduced peripheral count - notably omitting CTSU and full 40×4 LCD support. However, it shares identical pinout and peripheral mapping with other 64-pin RX113 parts (e.g., R5F51136ADFM#30), enabling footprint reuse across memory variants within the same package family.
