Product details
Overview
R5F5651EDGFC#V0 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 120 MHz (240 DMIPS), featuring on-chip 1.5 MB code flash, 640 KB SRAM, single-precision IEEE-754 FPU, Ethernet MAC, dual CAN, SD host/slave, QSPI, and GLCDC for embedded industrial HMI applications.
For engineers reviewing the R5F5651EDGFC#V0 datasheet, R5F5651EDGFC#V0 pinout, R5F5651EDGFC#V0 application, or R5F5651EDGFC#V0 equivalent, key selection criteria include 120-MHz real-time performance with MPU, dual-bank flash for safe firmware updates, integrated Ethernet PHY support, and 136 GPIOs with 5-V tolerance in a 176-pin LFBGA package.
Technical Context
The R5F5651EDGFC#V0 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and hardware FPU compliant with IEEE-754 single-precision. It supports memory protection via an 8-region MPU and secure boot through Trusted Memory (TM) with instruction-only execution from protected flash regions.
Clocking is managed by a flexible system including PLL-based 120-MHz ICLK, independent PCLKA/PCLKB domains (up to 120/60 MHz), and dedicated IWDT oscillator. Peripheral timing is decoupled: ETHERC, GLCDC, and DRW2D run on PCLKA; S12AD units use PCLKC/PCLKD; external bus operates at up to 60 MHz BCLK.
