Overview
R5F51118ADFM#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 512 KB on-chip flash, 64 KB SRAM, 8 KB data flash, 14-channel 12-bit ADC, dual 8-bit DAC, USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and operation from −40°C to +85°C in a 64-pin LFQFP package. It targets embedded control in industrial HMI, portable medical devices, and USB-connected sensor nodes.
For engineers reviewing the R5F5118ADFM#30 datasheet, R5F51118ADFM#30 pinout, R5F51118ADFM#30 application, or R5F51118ADFM#30 equivalent, this page delivers verified specifications, package mapping, functional pin roles, real-world use cases, and validated alternative parts - all grounded in Renesas' official R01DS0190EJ0130 Rev.1.30 documentation.
Technical Context
The R5F51118ADFM#30 implements the RXv1 core with Harvard architecture, five-stage pipeline, and variable-length instructions enabling ultra-compact code. Its clock system integrates a 32 MHz ±1% high-speed on-chip oscillator, PLL, sub-clock (32.768 kHz), and CAC for frequency accuracy measurement - supporting independent ICLK/PCLK/FCLK domains.
Peripheral integration includes an Event Link Controller (ELC) enabling direct module-to-module triggering without CPU intervention, a Data Transfer Controller (DTC) with chain transfer for efficient memory moves, and MTU2 timers with complementary PWM and phase counting modes - all optimized for deterministic real-time response in motor control and power conversion.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F51118ADFM#30?
The R5F51118ADFM#30 operates at up to 32 MHz when supplied with 2.7–3.6 V, 16 MHz at 2.4–2.7 V, and 8 MHz at 1.8–2.4 V. Its high-speed on-chip oscillator achieves ±1% accuracy across −40°C to +85°C, eliminating need for external crystal in many timing-tolerant applications. The R5F51118ADFM#30 maintains full peripheral functionality across its entire voltage range.
Does the R5F51118ADFM#30 support USB On-The-Go (OTG) and Battery Charging (BC) detection?
Yes, the R5F5118ADFM#30 integrates a USB 2.0 full-speed host/function/OTG module compliant with USB BC v1.2. It detects SDP (standard downstream port), CDP (charging downstream port), and DCP (dedicated charging port) using internal circuitry - enabling automatic role negotiation and optimal charging current selection without external components. The R5F51118ADFM#30 supports isochronous transfers for real-time audio/data streaming.
How many ADC channels does the R5F51118ADFM#30 support, and what is its minimum conversion time?
The R5F51118ADFM#30 features a 12-bit successive-approximation ADC with up to 14 input channels (AN000–AN004, AN006, AN008–AN015). At 32 MHz ADCLK, its minimum conversion time is 1.0 µs per channel. It supports scan modes (single, continuous, group), double-trigger mode for synchronized sampling, and external trigger inputs - making it suitable for motor control and multi-sensor acquisition. The R5F51118ADFM#30 includes an integrated temperature sensor routed to the ADC.
What low-power modes are available on the R5F51118ADFM#30, and what is the wake-up time from software standby?
The R5F51118ADFM#30 offers three low-power modes: sleep, deep sleep, and software standby. In software standby mode, current consumption drops to 0.44 µA (typical), and wake-up time is 4.8 µs - triggered by RTC alarm, external interrupt, or ELC event. The RTC remains active during standby, enabling precise timekeeping and periodic wake-ups. The R5F51118ADFM#30 retains SRAM contents and register states across all low-power modes.
Is the R5F51118ADFM#30 pin-compatible with other RX111 Group MCUs in the same package?
Yes, all RX111 Group MCUs in the PLQP0064KB-A (64-pin LFQFP) package - including R5F51118ADFM#30, R5F51117ADFM#3A, and R5F51118AGFM#3A - share identical pinouts and electrical characteristics. Peripheral enablement varies by memory size and temperature grade, but pin function mapping, drive strength, and voltage tolerances are consistent. The R5F51118ADFM#30 can be substituted without PCB changes when flash/SRAM requirements align.
