Overview
R5F51135ADLJ#20 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 KB on-chip flash, 32 KB SRAM, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, 12-bit A/D (17 channels), 12-bit D/A (2 channels), RTC, LCD controller (40×4), CTSU (12-channel capacitive touch), and operates from 1.8–3.6 V across –40 to +85°C. It targets embedded human-interface and low-power industrial control applications.
For engineers reviewing the R5F51135ADLJ#20 datasheet, R5F51135ADLJ#20 pinout, R5F51135ADLJ#20 application, or R5F51135ADLJ#20 equivalent, this page delivers verified specifications, package mapping to PTLG0100JA-A (7×7 mm TFLGA), validated peripheral capabilities including USB OTG, CTSU, and RTC, and confirmed alternative options for migration or sourcing continuity.
Technical Context
The R5F51135ADLJ#20 implements the RXv1 core with CISC Harvard architecture, five-stage pipeline, and variable-length instructions enabling ultra-compact code. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), all managed via the Clock Frequency Accuracy Measurement Circuit (CAC).
Peripheral coordination is handled by the Event Link Controller (ELC), which enables direct module-to-module triggering without CPU intervention-e.g., MTU2 generating A/D start triggers-while the Data Transfer Controller (DTC) supports four transfer modes with interrupt-driven chaining. The MCU supports IEC 60730 compliance via built-in RAM test assist, IWDT, and CAC.
