Product details
Overview
R5F51137ADLJ#2A from Renesas is a 32-bit RX113 Group microcontroller featuring a 32 MHz CPU core delivering 50 DMIPS, 384 KB on-chip flash memory, 64 KB SRAM, and 8 KB data flash with 1M erase/write cycles. It integrates USB 2.0 full-speed host/function/OTG, 17-channel 12-bit A/D converter (1.0 µs min conversion), dual 12-bit D/A outputs, LCD controller (40×4 segment), capacitive touch sensing (12 channels), RTC, and operates from 1.8–3.6 V across –40 to +85°C in a 100-pin TFLGA package.
For engineers reviewing the R5F51137ADLJ#2A datasheet, R5F51137ADLJ#2A pinout, R5F51137ADLJ#2A application, or R5F51137ADLJ#2A equivalent, this MCU supports low-power embedded designs requiring integrated USB connectivity, high-resolution analog I/O, capacitive touch UI, and real-time clock functionality - especially where compact 7×7 mm footprint and BGA reliability are critical.
Technical Context
The R5F51137ADLJ#2A implements a CISC Harvard-architecture RX CPU with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply operations. Its clock system includes a ±1% 32 MHz high-speed on-chip oscillator, sub-clock (32.768 kHz), PLL, and USB-dedicated PLL - all configurable via independent ICLK/PCLK/FCLK domains.
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 44 event sources. The CTSU provides self- and mutual-capacitance touch sensing with on-chip noise cancellation, validated for 12 detection pins in the 100-pin TFLGA variant.
