For engineers reviewing the R5F51116ADFK#30 datasheet, R5F51116ADFK#30 pinout, R5F51116ADFK#30 application, or R5F51116ADFK#30 equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, −40°C to +85°C temperature grade, USB OTG support with BC (Battery Charger) compliance, and integrated E2 DataFlash endurance of 1,000,000 erase/write cycles.
Technical Context
The R5F51116ADFK#30 implements a CISC Harvard-architecture RX CPU core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply operations. It integrates an Event Link Controller (ELC) enabling direct module-to-module triggering without CPU intervention, and supports background operation (BGO) for concurrent data flash programming during code execution.
Its clock system includes independent PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), with configurable ICLK/PCLK/FCLK domains. Power management features three low-power modes, including software standby with 4.8 μs wake-up and 0.44 μA supply current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51116ADFM#3A | Same core, memory, and peripherals; differs only in package (64-pin LFQFP, 10×10 mm, 0.5 mm pitch) | Requires PCB redesign due to different footprint and pitch; better suited for space-constrained layouts needing finer pitch | Select when board layout prioritizes smaller footprint and higher pin density over mechanical robustness of LQFP. |
| R5F51115ADFK#3A | Lower memory: 128 KB flash / 16 KB RAM; otherwise identical peripheral set and package | Targeted at cost-sensitive designs where firmware size and RAM usage fit within reduced capacities | Choose when application firmware fits in 128 KB flash and does not require >16 KB runtime RAM. |
Compared with R5F51116ADFK#30, the R5F51116ADFM#3A offers identical functionality in a smaller 0.5 mm-pitch LFQFP, while R5F51115ADFK#3A reduces flash/RAM capacity by 50% - both retain USB OTG, ELC, and RTC but demand trade-offs in layout compatibility or memory headroom.

FAQ
What is the maximum operating frequency and voltage requirement for the R5F51116ADFK#30?
The R5F51116ADFK#30 operates at a maximum frequency of 32 MHz, which requires a supply voltage of 2.7 V to 3.6 V. At lower voltages (1.8–2.4 V), the max frequency is reduced to 8 MHz. This voltage-frequency scaling ensures stable operation across diverse power environments while maintaining 50 DMIPS performance at full speed.
Does the R5F51116ADFK#30 support USB On-The-Go (OTG) functionality?
Yes, the R5F51116ADFK#30 includes a USB 2.0 host/function module that fully supports OTG operation, including BC (Battery Charger) detection and isochronous transfers. Its integrated transceiver eliminates the need for an external PHY, and the USB0_ID pin enables automatic role switching between host and device modes in Mini-AB connector configurations.
How many analog input channels does the R5F51116ADFK#30's 12-bit A/D converter support?
The R5F51116ADFK#30 integrates a 12-bit A/D converter with up to 14 input channels (AN000–AN015, excluding AN005 and AN007). These channels support scan modes, double-trigger operation for motor control redundancy, and hardware triggering via MTU2 timers or the Event Link Controller - all accessible in the 64-pin LQFP package.
What low-power modes are available on the R5F51116ADFK#30, and what is the wake-up time from software standby?
The R5F51116ADFK#30 offers three low-power modes: sleep, deep sleep, and software standby. From software standby mode, it recovers in 4.8 μs with supply current as low as 0.44 μA. This rapid wake-up enables responsive event-driven operation while minimizing energy consumption in battery-powered or energy-harvesting sensor nodes.
Is the R5F51116ADFK#30 pin-compatible with other RX111 Group MCUs in the same package?
Yes, all RX111 Group MCUs in the PLQP0064GA-A (64-pin LQFP) package - including R5F51116ADFK#30, R5F51115ADFK#3A, and R5F51118ADFK#3A - share identical pinouts and electrical characteristics. Firmware and hardware designs can be scaled across memory variants without PCB changes, provided peripheral usage remains within the selected part's functional subset.
