Product details
Overview
R5F51111AGFK#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 32 KB on-chip flash, 10 KB SRAM, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, 12-bit A/D converter (14 channels), 8-bit D/A converter (2 channels), RTC, and operates across −40°C to +105°C. It targets compact industrial control and USB-enabled sensor nodes.
For engineers reviewing the R5F51111AGFK#3A datasheet, R5F51111AGFK#3A pinout, R5F51111AGFK#3A application, or R5F51111AGFK#3A equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, USB OTG capability with BC support, 1.0 µs A/D conversion time, and IEC 60730-compliant safety features for functional safety designs.
Technical Context
The R5F51111AGFK#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 includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and CAC for frequency accuracy monitoring.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module-to-module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers triggered by 35+ event sources - critical for deterministic real-time response in motor control and USB data streaming.
