Product details
Overview
R5F5651EHGFM#10 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with integrated FPU, 240 DMIPS performance, 2 MB on-chip code flash (dual-bank), 640 KB SRAM, Ethernet MAC, CAN 2.0B, SD host/slave, QSPI, and hardware AES-128/192/256 encryption - designed for industrial HMI, networked gateways, and secure IoT edge nodes requiring real-time control and connectivity.
For engineers reviewing the R5F5651EHGFM#10 datasheet, R5F5651EHGFM#10 pinout, R5F5651EHGFM#10 application, or R5F5651EHGFM#10 equivalent, this MCU delivers deterministic real-time execution, IEC 60730-compliant safety features, dual-bank flash for safe firmware updates, and integrated peripherals including GLCDC + DRW2D for embedded graphics - critical for BOM-stable, long-lifecycle industrial designs.
Technical Context
The R5F5651EHGFM#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a single-precision IEEE-754 FPU, two MAC units, and a 32-bit multiplier with one-cycle execution - supporting high-accuracy motor control and sensor fusion algorithms.
Its clock system combines external crystal support (8–24 MHz), internal PLL, and multiple on-chip oscillators (LOCO, HOCO, IWDT-dedicated) to drive independent peripheral clocks: PCLKA up to 120 MHz (for ETHERC, GLCDC, DRW2D), PCLKB up to 60 MHz (for timers, ADC, UART), and dedicated ADCLKs for dual 12-bit S12AD units - enabling precise timing isolation across mixed-signal subsystems.
