Product details
Overview
R5F51116ADFL#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 Kbytes of on-chip flash, 32 Kbytes of SRAM, 8 Kbytes of data flash, 14-channel 12-bit A/D converter (1.0 µs conversion time), and dual 8-bit D/A outputs - deployed in industrial HMI, sensor node control, and USB-connected embedded instrumentation.
For engineers reviewing the R5F51116ADFL#30 datasheet, R5F51116ADFL#30 pinout, R5F51116ADFL#30 application, or R5F51116ADFL#30 equivalent, this page delivers verified package mapping (PLQP0048KB-A, 48-pin LFQFP), confirmed peripheral integration (USB 2.0 FS/OTG, RTC, ELC, DTC), thermal rating (−40°C to +85°C), and validated alternative selection guidance.
Technical Context
The R5F51116ADFL#30 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 frequency accuracy monitoring.
Peripheral coordination is handled via Event Link Controller (ELC) enabling direct module-to-module triggering without CPU intervention, and Data Transfer Controller (DTC) supporting chain transfers across four modes. The MCU supports IEC 60730-compliant safety functions including IWDT with dedicated 15-kHz oscillator and RAM test assist logic.

The R5F51116ADFL#30 operates at up to 32 MHz when supplied with 2.7 V to 3.6 V. At 1.8 V to 2.4 V, max frequency is 8 MHz; at 2.4 V to 2.7 V, it is 16 MHz. Supply current is 3.2 mA (typ.) at 32 MHz, and software standby mode draws just 0.44 μA - enabling battery-powered deployments. The R5F51116ADFL#30 maintains full peripheral functionality across its rated voltage range.
Does the R5F51116ADFL#30 support USB device, host, and OTG modes simultaneously?
Yes - the R5F51116ADFL#30 integrates a single-port USB 2.0 controller compliant with full-speed (12 Mbps) and low-speed (1.5 Mbps) operation, supporting device, host (with ≥32 Kbytes ROM), and On-The-Go (OTG) modes. It includes BC (Battery Charger) detection and isochronous transfer, enabling direct connection to PCs, peripherals, and charging ports without external hub logic. The R5F51116ADFL#30 uses internal transceivers and requires no external PHY.
How many A/D and D/A channels does the R5F51116ADFL#30 include, and what are their key specs?
The R5F51116ADFL#30 includes a 14-channel 12-bit successive-approximation A/D converter with 1.0 µs minimum conversion time at 32 MHz ADCLK, plus double-trigger mode for redundant sampling. It also provides two 8-bit voltage-output D/A channels (DA0, DA1), each delivering 0 V to VCC - available only in 48-pin and larger packages like the R5F51116ADFL#30. These DACs support calibration signal generation and analog actuator control.
What low-power modes are available on the R5F51116ADFL#30, and what is the wake-up latency from standby?
The R5F51116ADFL#30 supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, current consumption drops to 0.44 μA, and recovery time to full operation is 4.8 μs - among the fastest in its class. Wake-up sources include RTC alarm, external interrupt (IRQ0–IRQ7), and USB resume. The R5F51116ADFL#30 retains SRAM and register contents in all low-power states except reset.
Is the R5F51116ADFL#30 qualified for functional safety standards such as IEC 60730?
Yes - the R5F5116ADFL#30 includes hardware features required for Class B compliance per IEC 60730: independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, clock frequency accuracy measurement circuit (CAC), RAM test assist logic, and voltage monitoring with dual LVD circuits. These are documented in Renesas' RX111 Functional Safety Manual (R01US0097EJ0100), confirming the R5F51116ADFL#30's suitability for appliance control and industrial safety-critical subsystems.
