Product details
Overview
R5F51111ADFL#3A from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 32 KB on-chip flash, 10 KB SRAM, 8 KB data flash, 12-bit A/D converter (14 channels), USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial sensor nodes requiring deterministic real-time control and low-power connectivity.
For engineers reviewing the R5F51111ADFL#3A datasheet, R5F51111ADFL#3A pinout, R5F51111ADFL#3A application, or R5F51111ADFL#3A equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C 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 R5F51111ADFL#3A implements a CISC Harvard architecture with five-stage pipeline and variable-length instruction encoding, enabling ultra-compact code and single-cycle instruction execution. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for IEC 60730-compliant frequency accuracy monitoring.
It supports three low-power modes - sleep, deep sleep, and software standby (0.44 μA, 4.8 μs wake-up) - with module stop control and independent watchdog timer (IWDT) driven by a dedicated 15 kHz on-chip oscillator. The ELC enables direct hardware-triggered operation between peripherals (e.g., MTU → A/D conversion start) without CPU intervention.

It supports full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, isochronous transfers, and detects DCP/CDP/SDP charger types - allowing the R5F51111ADFL#3A to act as either a USB host or device while negotiating optimal charging current from attached sources.
What are the memory resources available on the R5F51111ADFL#3A?
The R5F51111ADFL#3A includes 32 KB of on-chip flash memory (executed at full 32 MHz with zero wait states), 10 KB of SRAM, and 8 KB of data flash rated for 1,000,000 erase/write cycles. The data flash supports Background Operation (BGO), enabling firmware updates or parameter logging without halting application execution - a key feature for reliable R5F51111ADFL#3A deployments.
How does the Event Link Controller (ELC) enhance real-time performance in the R5F51111ADFL#3A?
The ELC in the R5F51111ADFL#3A enables direct hardware-level linking of 35 event sources (e.g., MTU2 overflow, A/D conversion complete) to target peripherals (e.g., A/D start, DAC update) without CPU or interrupt involvement. This reduces latency to one cycle, eliminates ISR overhead, and allows the CPU to remain in low-power modes - significantly improving determinism and efficiency in R5F51111ADFL#3A-based motor control or sensor fusion systems.
