Product details
Overview
R5F51118AGFK#3A from Renesas is a 32-bit RX111 Group microcontroller featuring a 32 MHz CPU core delivering 50 DMIPS, 512 KB on-chip flash memory (no wait states), 64 KB SRAM, and integrated USB 2.0 host/function/OTG controller. It includes a 12-bit A/D converter (14 channels, 1.0 µs conversion), 8-bit D/A converter (2 channels), RTC with calendar mode, and operates across −40 to +105°C for industrial motor control and embedded HMI applications.
For engineers reviewing the R5F51118AGFK#3A datasheet, R5F51118AGFK#3A pinout, R5F51118AGFK#3A application, or R5F51118AGFK#3A equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases, and validated alternative parts - all aligned to the PLQP0064GA-A (14 × 14 mm, 0.8 mm pitch) LQFP-64 package and G-grade temperature rating.
Technical Context
The R5F51118AGFK#3A implements a CISC Harvard architecture RX CPU with five-stage pipeline, variable-length instruction encoding, and ultra-compact code density. Its clock system integrates a high-speed on-chip oscillator (32 MHz ±1% over −20 to +85°C), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), enabling precise timing control for USB, RTC, and low-power modes.
Peripheral coordination is handled via the Event Link Controller (ELC), allowing direct module-to-module triggering without CPU intervention - critical for deterministic motor control and sensor data acquisition. The Data Transfer Controller (DTC) supports chain transfers across four modes, reducing interrupt overhead during high-bandwidth ADC or USB data streaming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RX 32-bit CISC Harvard, 32 MHz max, 50 DMIPS - enables real-time control loops with <4.8 µs wake-from-standby latency. |
| Memory | 512 KB flash (no wait states at 32 MHz), 64 KB SRAM, 8 KB data flash (1M erase/write cycles) - supports field firmware updates and parameter storage. |
| ADC/DAC | 12-bit A/D converter (14 ch, 1.0 µs min conversion), 8-bit D/A (2 ch, 0–VCC output) - suitable for closed-loop analog feedback in motor drives. |
| USB Interface | USB 2.0 full-speed host/function/OTG (12 Mbps), isochronous transfer, BC support - enables direct peripheral attachment and battery charging detection. |
| Low-Power Modes | Software standby mode (0.44 µA), recovery in 4.8 µs - ideal for battery-powered HMI and sensor nodes requiring rapid wake-up. |
| Operating Range | −40 to +105°C (G-grade), 1.8–3.6 V supply - qualified for under-hood automotive and industrial control environments. |
| Package | LQFP-64 (PLQP0064GA-A), 14 × 14 mm, 0.8 mm pitch - compatible with standard PCB assembly processes and thermal management requirements. |
Pinout & Package
Package: PLQP0064GA-A - 64-pin LQFP, 14 × 14 mm body, 0.8 mm pitch, lead-free (Sn only), RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual power domains: VCC (1.8–3.6 V digital/analog), VSS (common reference); decoupling required per datasheet layout guidelines. |

Key Features
| Feature | Design Value |
|---|---|
| Event Link Controller (ELC) | Direct hardware linking of 35 event sources (e.g., timer overflow → ADC trigger) eliminates CPU polling and reduces jitter in time-critical sequences. |
| Background Operation (BGO) | Data flash writes/erases execute concurrently with program execution - enables seamless firmware updates without halting real-time tasks. |
| Independent Watchdog (IWDT) | Dedicated 15 kHz on-chip oscillator ensures reliable timeout detection even if main clock fails - critical for functional safety compliance (IEC 60730). |
