Product details
Overview
R5F51118ADFK#3A 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, USB 2.0 host/function/OTG, 12-bit A/D (14 channels), 8-bit D/A (2 channels), RTC, and operation from 1.8–3.6 V across −40 to +85°C. It targets embedded control in industrial HMI, portable medical devices, and USB-connected sensor nodes.
For engineers reviewing the R5F5118ADFK#3A datasheet, R5F51118ADFK#3A pinout, R5F51118ADFK#3A application, or R5F51118ADFK#3A equivalent, key selection criteria include USB OTG support with BC compliance, integrated 12-bit ADC with double-trigger for motor sensing, low-power software standby mode (0.44 μA), and 64-pin LQFP (PLQP0064GA-A) package compatibility.
Technical Context
The R5F51118ADFK#3A implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for accuracy monitoring - all configurable per domain (ICLK/PCLK/FCLK).
Peripheral coordination is handled via Event Link Controller (ELC), allowing direct module triggering without CPU intervention, and Data Transfer Controller (DTC) supporting chain transfers triggered by 82 interrupt sources. The MCU supports IEC 60730 Class B compliance through IWDT, RAM test assist, and clock accuracy measurement.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51118ADFK#3A?
The R5F51118ADFK#3A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its RX CPU core features a five-stage pipeline, single-cycle instruction execution for basic operations, and a 64-bit accumulator for 32×32-bit multiply results - enabling deterministic real-time response in control applications. This performance level is sustained across its full −40°C to +85°C operating range.
Does the R5F51118ADFK#3A support USB On-The-Go (OTG) and Battery Charging (BC) specifications?
Yes, the R5F51118ADFK#3A integrates a USB 2.0 host/function module that fully supports On-The-Go (OTG) and Battery Charging (BC) v1.2. It enables dynamic role switching between host and device modes and detects standard downstream ports (SDP), charging downstream ports (CDP), and dedicated charging ports (DCP) - critical for field-upgradable embedded devices using R5F51118ADFK#3A as their USB interface controller.
What are the low-power capabilities of the R5F51118ADFK#3A, and how fast is wake-up from standby?
The R5F51118ADFK#3A offers three low-power modes, with software standby drawing just 0.44 μA. Recovery from this mode takes only 4.8 μs - among the fastest in its class - allowing rapid resumption of sensor sampling or communication tasks. This capability, combined with programmable peripheral clocks and module stop control, makes R5F51118ADFK#3A ideal for battery-constrained applications where responsiveness and energy efficiency are both essential.
How many A/D and D/A channels does the R5F51118ADFK#3A provide, and what are their key specs?
The R5F51118ADFK#3A includes a 12-bit A/D converter with up to 14 input channels and a minimum conversion time of 1.0 μs at 32 MHz ADCLK, plus two 8-bit D/A channels with 0 V to VCC output range. The A/D supports double-trigger mode for synchronized sampling - especially valuable in motor control - and shares its reference and analog supply pins (VREFH0/VREFL0/AVCC0/AVSS0) with the integrated temperature sensor, simplifying analog subsystem design in R5F51118ADFK#3A-based systems.
Is the R5F51118ADFK#3A pin-compatible with other members of the RX111 Group?
Yes, the R5F51118ADFK#3A in the PLQP0064GA-A (64-pin LQFP) package is pin-compatible with all other RX111 Group MCUs in the same 64-pin LQFP variant - including R5F51117ADFK#3A and R5F51116ADFK#3A. Peripheral pin assignments, power/ground locations, and USB/oscillator interfaces match exactly, enabling hardware reuse across firmware variants and memory configurations without PCB redesign - a key advantage when scaling R5F51118ADFK#3A-based platforms.
