Overview
R5F5651CDDFM#10 from Renesas is a 32-bit RXv2 core MCU operating at up to 120 MHz (240 DMIPS), featuring 1 MB code flash, 256 KB SRAM, single-precision IEEE-754 FPU, Ethernet MAC, dual CAN, SD host/slave, QSPI, and hardware AES-128/192/256 encryption - deployed in industrial HMI gateways requiring real-time connectivity, secure firmware updates, and local graphics rendering.
For engineers reviewing the R5F5651CDDFM#10 datasheet, R5F5651CDDFM#10 pinout, R5F5651CDDFM#10 application, or R5F5651CDDFM#10 equivalent, this page delivers verified package mapping (PLQP0176KB-A, 176-pin LQFP), confirmed peripheral clock domains (ICLK ≤120 MHz, PCLKA ≤120 MHz, PCLKB ≤60 MHz), exact memory partitioning (256 KB SRAM, 32 KB data flash), and validated alternative selection for IEC60730-compliant embedded control designs.
Technical Context
The R5F5651CDDFM#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and MPU-enforced memory protection across eight configurable regions. It integrates dual-bank flash for safe background programming and startup bank swapping during field updates.
Clock subsystem includes PLL-driven ICLK (120 MHz), independent PCLKA (120 MHz for ETHERC/DRW2D/GLCDC), PCLKB (60 MHz for TMR/CMT/S12AD unit 0), and dedicated ADCLK domains (PCLKC/PCLKD, both ≤60 MHz) enabling precise timing isolation for analog and communication peripherals.

FAQ
What is the maximum operating frequency and CPU performance of the R5F5651CDDFM#10?
The R5F5651CDDFM#10 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS of processing performance using the RXv2 CPU core. Its single-precision IEEE-754 floating-point unit enables efficient execution of sensor fusion, motor control, and graphics calculations. This performance level is sustained across the full operating temperature range (–40°C to +85°C) with no derating required.
Does the R5F5651CDDFM#10 support secure boot and firmware authentication?
Yes, the R5F5651CDDFM#10 supports secure boot through its Trusted Secure IP (TSIP) module and Trusted Memory (TM) function. TM protects designated code flash regions from read-out, allowing only CPU instruction fetch - preventing firmware extraction. TSIP provides hardware-accelerated AES encryption and secure key storage, enabling authenticated and encrypted firmware updates without exposing keys in software.
What graphics capabilities does the R5F5651CDDFM#10 provide for HMI development?
The R5F5651CDDFM#10 integrates a Graphic-LCD Controller (GLCDC) supporting 3-layer plane overlay and a 2D Drawing Engine (DRW2D) capable of vector drawing, bit blitting, rotation, and texture mapping. It supports 32-/16-/8-bit pixel formats and CLUT-based color lookups. These features enable responsive, resource-efficient GUI rendering directly on the R5F5651CDDFM#10 without external GPU or frame buffer memory.
Can the R5F5651CDDFM#10 operate in low-power modes while maintaining RTC and SRAM retention?
Yes, the R5F5651CDDFM#10 supports four low-power modes, including deep software standby where the main CPU and most peripherals halt while retaining 8 KB of standby RAM and sustaining RTC operation - even when VCC drops, provided VBATT is connected. The RTC remains fully functional with calendar, alarm, and time-capture features active, enabling wake-up events without external components.
Which communication interfaces are supported by the R5F5651CDDFM#10 for industrial networking?
The R5F5651CDDFM#10 supports Ethernet MAC (10/100 Mbps MII/RMII), two ISO11898-1 CAN channels (32 mailboxes each), SD host/slave, QSPI, three RSPI, three I²C (RIIC), and thirteen SCI interfaces. This combination enables robust industrial networking - including Modbus TCP over Ethernet, CANopen diagnostics, SD-based firmware logging, and SPI-connected sensors - all concurrently managed via the ELC and multiple DMA controllers.
