Product details
Overview
R5F51118ADFL#1A 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 DACs, USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial HMI, sensor fusion nodes, and USB-connected embedded control systems.
For engineers reviewing the R5F5118ADFL#1A datasheet, R5F51118ADFL#1A pinout, R5F51118ADFL#1A application, or R5F51118ADFL#1A equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C to +85°C temperature grade, USB OTG capability with BC support, 1.0 µs ADC conversion time, and integrated event link controller for low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F51118ADFL#1A implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and CAC for IEC 60730 compliance.
Peripheral integration includes DTC for interrupt-triggered transfers, ELC for direct module-to-module event chaining (e.g., MTU→ADC trigger), and POE2 for waveform output pin impedance control. It supports three low-power modes - sleep, deep sleep, and software standby (0.44 µA, 4.8 µs wake-up) - with voltage detection (LVDA) across 14 programmable thresholds.

FAQ
What is the maximum operating frequency and core performance of the R5F51118ADFL#1A?
The R5F51118ADFL#1A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS (Dhrystone MIPS) performance. Its RX CPU core features a five-stage pipeline, variable-length instruction encoding, and a 64-bit accumulator capable of single-cycle 32×32 multiplication with 64-bit result - enabling deterministic real-time control in motor and sensor applications.
Does the R5F51118ADFL#1A support USB On-The-Go (OTG) functionality?
Yes, the R5F51118ADFL#1A integrates a USB 2.0 host/function module that fully supports OTG operation, including BC (Battery Charger) detection, full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, and isochronous transfers. The USB0_ID pin enables automatic role switching between host and device based on Mini-AB connector detection - essential for portable field-service tools.
What low-power modes are available on the R5F51118ADFL#1A, and what is the lowest current draw?
The R5F51118ADFL#1A offers three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it draws just 0.44 µA (typical) while retaining SRAM content and RTC operation, with wake-up latency of 4.8 µs via RTC alarm or external interrupt - ideal for battery-backed data loggers and wireless sensor endpoints.
How many analog-to-digital converter (ADC) channels does the R5F51118ADFL#1A support, and what is its minimum conversion time?
The R5F51118ADFL#1A includes a 12-bit A/D converter 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 also supports double-trigger mode for synchronized sampling - critical for motor current and voltage measurement in BLDC control loops.
Is the R5F51118ADFL#1A pin-compatible with other members of the RX111 Group?
No - the R5F51118ADFL#1A uses a 48-pin LFQFP (PLQP0048KB-A) package, while other RX111 variants use 36-, 40-, 64-, or WFLGA packages. Pin mapping differs across packages; for example, DA0/DA1 and certain MTU2 pins are unavailable on 36-pin versions. Always verify pin functions using Table 1.2 and Figure 1.5 in the R01DS0190EJ0130 datasheet for R5F51118ADFL#1A.
