Product details
Overview
R5F5111JADFL#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 16 KB on-chip flash, 8 KB SRAM, and 8 KB data flash. It integrates a 12-bit A/D converter (14 channels), USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and operates from 1.8–3.6 V across −40 to +85°C - deployed in industrial sensor nodes and low-power HMI controllers.
For engineers reviewing the R5F5111JADFL#3A datasheet, R5F5111JADFL#3A pinout, R5F5111JADFL#3A application, or R5F5111JADFL#3A equivalent, key selection criteria include its 64-pin LFQFP (PLQP0048KB-A) package, USB OTG capability, software standby current of 0.44 μA, 4.8 μs wake-up time, and IEC 60730-compliant safety features for embedded control.
Technical Context
The R5F5111JADFL#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 82 interrupt sources - critical for deterministic real-time response in motor control and sensor fusion.
