Product details
Overview
R5F5651EHGFM#30 from Renesas is a 32-bit RXv2 microcontroller with 120 MHz max operating frequency, 240 DMIPS performance, single-precision IEEE-754 FPU, 2 MB on-chip code flash memory (dual-bank), and 640 KB SRAM. It integrates Ethernet MAC, CAN, USB 2.0 FS host/function, SD host/slave, QSPI, GLCDC, DRW2D, and hardware AES/TSIP encryption - targeting industrial HMI, networked gateways, and secure edge controllers.
For engineers reviewing the R5F5651EHGFM#30 datasheet, R5F5651EHGFM#30 pinout, R5F5651EHGFM#30 application, or R5F5651EHGFM#30 equivalent, this MCU delivers deterministic real-time control with integrated graphics acceleration, dual-bank safe firmware updates, and IEC60730-compliant safety features for certified embedded systems.
Technical Context
The R5F5651EHGFM#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It supports little-endian or big-endian data arrangement and includes two 72-bit accumulators, 16 general-purpose 32-bit registers, and dedicated DSP/FPU instruction sets.
Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL to generate up to 120 MHz ICLK, while independent peripheral clocks (PCLKA/B/C/D up to 120/60/60/60 MHz) enable precise timing isolation for Ethernet, ADC, and display subsystems.
