Product details
Overview
R5F51116ADFK#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, USB 2.0 full-speed host/function/OTG, 12-bit A/D converter (14 channels), 8-bit D/A converter (2 channels), RTC, and integrated low-power modes - deployed in industrial sensor nodes requiring deterministic real-time control and embedded USB connectivity.
For engineers reviewing the R5F51116ADFK#3A datasheet, R5F51116ADFK#3A pinout, R5F51116ADFK#3A application, or R5F51116ADFK#3A equivalent, this page delivers verified package mapping (PLQP0064GA-A, 64-pin LQFP, 14 × 14 mm, 0.8 mm pitch), confirmed peripheral channel counts (6 MTU channels, 3 SCI, 1 RIIC, 1 RSPI), supply voltage range (1.8–3.6 V), and temperature grade (−40 to +85°C).
Technical Context
The R5F51116ADFK#3A implements a CISC Harvard architecture with five-stage pipeline, variable-length instruction encoding, and on-chip debugging via FINE interface. Its 32-bit RX core supports 64-bit accumulator operations and single-cycle 32×32 multiplication, enabling efficient motor control and signal processing.
It integrates an Event Link Controller (ELC) for direct module-to-module triggering without CPU intervention, and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by 82 interrupt sources - reducing latency in time-critical I/O handling and background data movement.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51116ADFK#3A?
The R5F51116ADFK#3A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its 32-bit RX CPU core features a five-stage pipeline, variable-length instructions, and single-cycle 32×32 multiplication - enabling efficient execution of real-time control algorithms and communication stacks. This performance level is sustained across its full 1.8–3.6 V supply range.
Does the R5F51116ADFK#3A support USB device and host functionality simultaneously?
No, the R5F51116ADFK#3A supports USB 2.0 full-speed host, function, or OTG modes - but not simultaneous host+function operation. In OTG mode, it dynamically switches roles based on ID pin state and VBUS detection. The USB module includes an integrated transceiver, BC (Battery Charger) detection, and isochronous transfer support - all implemented within the single R5F51116ADFK#3A die.
How many analog-to-digital and digital-to-analog channels does the R5F51116ADFK#3A provide?
The R5F51116ADFK#3A integrates a 12-bit A/D converter with up to 14 input channels (AN000–AN004, AN006, AN008–AN015) and two independent 8-bit D/A converters (DA0, DA1). The D/A outputs are available only on 64-pin packages such as the PLQP0064GA-A used by R5F51116ADFK#3A, and deliver 0–VCC analog voltage outputs with monotonicity guaranteed.
What low-power modes are supported by the R5F51116ADFK#3A, and what is the wake-up time from standby?
The R5F51116ADFK#3A supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, current consumption drops to 0.44 µA (typ.), and wake-up time is 4.8 µs - triggered by RTC alarm, external interrupt, or USB resume. This enables rapid responsiveness in battery-powered applications while maintaining ultra-low quiescent current.
Is the R5F51116ADFK#3A qualified for industrial temperature operation?
Yes, the R5F51116ADFK#3A is rated for industrial temperature operation from −40°C to +85°C (denoted by the "D" suffix in the part number). It undergoes full characterization across this range for parameters including flash programming voltage, ADC accuracy, oscillator stability, and I/O drive strength - ensuring reliable operation in factory automation, building controls, and outdoor equipment environments.
