Product details
Overview
R5F51137ADFM#3A 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, 8 KB data flash, USB 2.0 full-speed host/function/OTG, 17-channel 12-bit A/D converter, and LCD controller/driver for embedded control in industrial HMI and portable instrumentation.
For engineers reviewing the R5F51137ADFM#3A datasheet, R5F51137ADFM#3A pinout, R5F51137ADFM#3A application, or R5F51137ADFM#3A equivalent, this MCU delivers deterministic real-time performance with low-power operation (0.44 µA software standby), integrated capacitive touch sensing (CTSU), and hardware event linking (ELC) for interrupt-free peripheral coordination.
Technical Context
The R5F51137ADFM#3A implements the RXv1 CPU core with CISC Harvard architecture, five-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a dedicated 32 MHz ±1% high-speed on-chip oscillator, PLL circuit (4–8 MHz input), and USB-dedicated PLL for precise timing across mixed-signal and communication subsystems.
Its peripheral set includes an Event Link Controller (ELC) that routes 44 event signals directly between modules-such as MTU2 timers triggering A/D conversion-without CPU intervention, and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by 120 interrupt sources.
