Product details
Overview
R5F51135ADFP#30 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, 17-channel 12-bit A/D converter, dual 12-bit D/A converters, LCD controller/driver (40×4 segment), capacitive touch sensing unit (12 channels), RTC, and low-power software standby mode (0.44 µA). It targets embedded human-interface applications such as smart home control panels and portable medical devices.
For engineers reviewing the R5F51135ADFP#30 datasheet, R5F51135ADFP#30 pinout, R5F51135ADFP#30 application, or R5F51135ADFP#30 equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases for capacitive touch and USB OTG, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The R5F51135ADFP#30 implements the RXv1 CPU core with CISC Harvard architecture, five-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle instruction execution. Its clock system includes a high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), all managed 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 four transfer modes with interrupt-source-specific configuration. The CTSU uses self- and mutual-capacitance methods with on-chip noise cancellation for robust touch detection in noisy environments.
