Product details
Overview
R5F51117AGFK#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 384 KB on-chip flash, 64 KB SRAM, 8 KB data flash, 14-channel 12-bit ADC, dual 8-bit DACs, USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial HMI, sensor gateway, and USB-connected embedded control systems.
For engineers reviewing the R5F51117AGFK#3A datasheet, R5F51117AGFK#3A pinout, R5F51117AGFK#3A application, or R5F51117AGFK#3A equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, −40°C to +105°C extended temperature grade, integrated E2 DataFlash with 1M erase/write cycles, and hardware event linking (ELC) for low-latency peripheral coordination without CPU intervention.
Technical Context
The R5F51117AGFK#3A 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 IEC 60730 compliance.
Peripheral subsystems include DTC for interrupt-triggered memory transfers, ELC for direct module-to-module triggering (e.g., MTU timer → ADC start), and USB 2.0 controller supporting OTG, BC (Battery Charger), and isochronous transfer - all synchronized to independent ICLK/PCLK/FCLK domains with configurable division ratios.

The R5F51117AGFK#3A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS (Dhrystone MIPS) 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. The R5F51117AGFK#3A achieves this performance across its full −40°C to +105°C operating range with no wait states on flash access.
Does the R5F51117AGFK#3A support USB On-The-Go (OTG) functionality?
Yes, the R5F51117AGFK#3A integrates a USB 2.0 host/function module that fully supports OTG operation, including ID pin detection (USB0_ID), VBUS sensing (USB0_VBUS), and OTG transceiver control signals (USB0_EXICEN, USB0_VBUSEN). It complies with USB 2.0 specifications and supports full-speed (12 Mbps), low-speed (1.5 Mbps), isochronous transfers, and Battery Charging (BC) detection - all implemented in hardware without external PHY.
What are the analog capabilities of the R5F51117AGFK#3A?
The R5F51117AGFK#3A includes a 14-channel 12-bit successive-approximation ADC with minimum 1.0 µs conversion time at 32 MHz ADCLK, double-trigger mode for motor control, and flexible trigger sources (software, MTU, ELC, external). It also features two 8-bit voltage-output DACs (DA0, DA1), an on-chip temperature sensor, and dedicated analog supply pins (AVCC0/AVSS0/VREFH0/VREFL0) - all accessible in the 64-pin LQFP package.
How does the Event Link Controller (ELC) enhance real-time performance in the R5F5117AGFK#3A?
The ELC in the R5F5117AGFK#3A enables direct hardware-level triggering between 35 different peripheral events - such as MTU2 overflow, ADC end-of-conversion, or RTC alarm - without CPU or interrupt controller involvement. This reduces latency to one bus cycle, eliminates interrupt nesting delays, and allows the CPU to remain in low-power sleep modes while maintaining deterministic peripheral coordination - a key advantage for motor control and sensor fusion applications.
Is the R5F51117AGFK#3A qualified for extended temperature operation?
Yes, the R5F51117AGFK#3A is rated for −40°C to +105°C operation (G-grade), validated across its full electrical specification range. This qualification covers all core functions including 32 MHz CPU operation, USB transceiver timing, ADC accuracy, and data flash endurance - making it suitable for under-hood automotive modules, industrial drives, and outdoor IoT equipment where ambient temperatures exceed standard commercial limits.
