Product details
Overview
R5F5651CDGBP#20 from Renesas is a 32-bit RXv2 microcontroller with 120 MHz CPU, single-precision FPU, 240 DMIPS performance, 2 MB on-chip code flash, 640 KB SRAM, and integrated Ethernet MAC, CAN, USB 2.0 FS, SD host/slave, QSPI, and GLCDC for industrial HMI and networked edge devices.
For engineers reviewing the R5F5651CDGBP#20 datasheet, R5F5651CDGBP#20 pinout, R5F5651CDGBP#20 application, or R5F5651CDGBP#20 equivalent, this MCU delivers deterministic real-time control, IEC60730 safety support, hardware-accelerated graphics rendering, and dual-bank flash for secure firmware updates in resource-constrained embedded systems.
Technical Context
The R5F5651CDGBP#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) for secure partitioning. It integrates dual-clock domain operation: ICLK up to 120 MHz for CPU/flash, PCLKA up to 120 MHz for Ethernet/USB/GLCDC/DRW2D, and PCLKB up to 60 MHz for timers/ADC/DAC.
Its peripheral subsystem includes dedicated DMA controllers-DMACAa (8 channels), EXDMAC (2 channels), DTCb (1 channel), and EDMAC (Ethernet-specific)-enabling zero-CPU-overhead data movement between SRAM, peripherals, and external interfaces including SDRAM, SD, and Ethernet PHY.
