Product details
Overview
R5F51114AGFL#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 96 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 12-bit A/D converter (10 channels), USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial sensor nodes and low-power HMI control systems.
For engineers reviewing the R5F51114AGFL#3A datasheet, R5F51114AGFL#3A pinout, R5F51114AGFL#3A application, or R5F51114AGFL#3A equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40 to +105°C extended temperature grade, integrated USB transceiver with BC support, and dual 8-bit D/A outputs (available in 64-pin variants only - not present in this 48-pin variant).
Technical Context
The R5F51114AGFL#3A implements the RXv1 CPU core with Harvard architecture, five-stage pipeline, and variable-length instructions - enabling ultra-compact code and single-cycle instruction execution. It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 82 interrupt sources.
Its clock system includes a high-speed on-chip oscillator (32 MHz ±1% over −20 to +85°C), PLL, sub-clock (32.768 kHz), and Clock Accuracy Measurement (CAC) circuit for IEC 60730 compliance. The Event Link Controller (ELC) enables direct module-to-module triggering without CPU intervention, including wake-up from software standby mode via RTC alarm.
