It targets embedded control in industrial sensors and USB-connected edge devices.
For engineers reviewing the R5F51114ADFK#5A datasheet, R5F51114ADFK#5A pinout, R5F51114ADFK#5A application, or R5F51114ADFK#5A equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, −40 to +85°C temperature grade, USB OTG support with BC (Battery Charger) compliance, and integrated event link controller (ELC) for interrupt-free peripheral coordination.
Technical Context
The R5F51114ADFK#5A 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 integration includes DTC for interrupt-triggered transfers, ELC for direct module-to-module triggering without CPU involvement, and MTU2 with six 16-bit timer channels supporting complementary PWM, phase counting, and A/D trigger generation - all configurable via MPC for flexible pin assignment.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51114ADFK#5A?
The R5F51114ADFK#5A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its RX CPU core supports single-cycle 32×32-bit multiplication with 64-bit accumulation, enabling efficient signal processing and real-time control tasks without external co-processors. This performance level is sustained across its full 1.8–3.6 V supply range.
Does the R5F51114ADFK#5A support USB On-The-Go (OTG) and Battery Charging (BC) detection?
Yes, the R5F51114ADFK#5A integrates a full-featured USB 2.0 host/function/OTG module compliant with BC 1.2 specification. It detects D+/D− line states to identify standard downstream ports, charging downstream ports, and dedicated chargers - enabling automatic power negotiation and safe charging behavior in portable designs.
What are the analog capabilities of the R5F51114ADFK#5A, and are they available in the 64-pin LQFP package?
The R5F51114ADFK#5A includes a 12-bit A/D converter with up to 14 input channels and two 8-bit D/A converter channels. Both A/D and D/A functions are fully supported in the 64-pin LQFP (PLQP0064GA-A) package. The A/D converter achieves 1.0 μs minimum conversion time at 32 MHz ADCLK, and the D/A outputs deliver rail-to-rail voltage (0 V to VCC) with monotonicity guaranteed.
How does the Event Link Controller (ELC) enhance real-time responsiveness in the R5F51114ADFK#5A?
The ELC in the R5F51114ADFK#5A allows 35 internal event sources - such as timer overflows, A/D completion, or communication receive flags - to directly trigger actions in 16 target peripherals without CPU intervention. This eliminates interrupt latency and overhead, enabling deterministic sub-microsecond response for time-critical tasks like motor commutation or synchronized sensor sampling.
What low-power modes are available on the R5F51114ADFK#5A, and what is the lowest achievable current draw?
The R5F51114ADFK#5A offers three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it achieves 0.44 μA typical current draw while retaining SRAM contents, keeping the RTC active, and allowing wake-up via external interrupt, RTC alarm, or USB resume. Recovery to full 32 MHz operation takes just 4.8 μs.
