Product details
Overview
R5F51137ADFP#30 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, and 8 KB data flash. It integrates 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 or 36×8), capacitive touch sensing unit (12 channels), RTC, and CTSU - deployed in industrial HMI, portable medical devices, and smart sensor nodes.
For engineers reviewing the R5F51137ADFP#30 datasheet, R5F51137ADFP#30 pinout, R5F51137ADFP#30 application, or R5F51137ADFP#30 equivalent, this page delivers verified specifications, package mapping to PLQP0100KB-A (100-pin LFQFP), validated peripheral integration (USB, CTSU, LCD), low-power mode timing (4.8 µs wake-up), and direct alternative part comparisons for embedded control selection.
Technical Context
The R5F51137ADFP#30 implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz).
Peripheral coordination is managed via Event Link Controller (ELC), enabling module-to-module triggering without CPU intervention, and Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by 44 event sources - critical for deterministic real-time response in motor control and sensor fusion.
