Product details
Overview
R5F51137AGFP#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 384 KB on-chip flash, 64 KB SRAM, 8 KB data flash, and integrated USB 2.0 full-speed host/function/OTG. It supports capacitive touch sensing (12 channels), LCD controller/driver (40×4 SEG/COM), 12-bit A/D (17 ch), 12-bit D/A (2 ch), RTC, and operates from −40 to +105°C in a 100-pin LFQFP package - used in industrial HMI, smart sensor nodes, and USB-connected embedded control systems.
For engineers reviewing the R5F51137AGFP#3A datasheet, R5F51137AGFP#3A pinout, R5F51137AGFP#3A application, or R5F51137AGFP#3A equivalent, this page delivers verified specifications, validated package mapping (PLQP0100KB-A), confirmed peripheral integration (USBc, CTSU, LCDC), real-world use-value context, and two technically documented alternative parts for thermal-extended industrial designs.
Technical Context
The R5F51137AGFP#3A implements a CISC Harvard-architecture RX CPU core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system includes independent PLL, USB-dedicated PLL, IWDT oscillator (15 kHz), and CAC circuit for IEC 60730 compliance.
Peripheral coordination is managed via Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention - critical for low-latency motor control and touch response. The Data Transfer Controller (DTC) supports chain transfer across four modes, triggered by 44 event sources including MTU, SCI, and ADC interrupts.
