Product details
Overview
R5F51113AGFL#1A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 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 in a 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch) package - used in industrial sensor nodes and USB-connected embedded controllers.
For engineers reviewing the R5F51113AGFL#1A datasheet, R5F51113AGFL#1A pinout, R5F51113AGFL#1A application, or R5F51113AGFL#1A equivalent, this page delivers verified specifications, validated pin functions, confirmed peripheral capabilities (USB OTG, MTU2 timers, ELC), and real-world design context for rapid evaluation and integration into thermally demanding, USB-enabled control systems.
Technical Context
The R5F51113AGFL#1A 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 coordination is handled by the Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention - critical for low-latency motor control and power management. The Data Transfer Controller (DTC) supports chain transfers triggered by 35+ event sources, including MTU2 capture events and A/D conversion completion.
Key Specifications
