Product details
Overview
R5F51137ADFM#30 from Renesas is a 32-bit RX113 Group microcontroller with 384 KB flash, 64 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), featuring USB 2.0 full-speed host/function/OTG, 17-channel 12-bit A/D converter, 2-channel 12-bit D/A converter, LCD controller/driver (40×4), capacitive touch sensing unit (CTSU), and RTC - deployed in industrial HMI, portable medical devices, and smart sensor nodes.
For engineers reviewing the R5F51137ADFM#30 datasheet, R5F51137ADFM#30 pinout, R5F51137ADFM#30 application, or R5F51137ADFM#30 equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-A (64-pin LFQFP), validated pin functions, real-world use cases, and two confirmed alternative parts for design continuity.
Technical Context
The R5F51137ADFM#30 implements a CISC Harvard-architecture RX CPU core with five-stage pipeline, variable-length instructions, and on-chip debugging support. It integrates a Data Transfer Controller (DTC) with four transfer modes and chain capability, and an Event Link Controller (ELC) enabling direct inter-module triggering without CPU intervention - critical for low-latency sensor-to-actuator response.
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. Power management supports three low-power modes, including software standby with 0.44 µA consumption and 4.8 µs wake-up time.
