Renesas R5F5651EHDFM#10

Overview

R5F5651EHDFM#10 from Renesas is a 32-bit RXv2 microcontroller operating at up to 120 MHz, delivering 240 DMIPS with integrated single-precision IEEE-754 FPU, 2 MB on-chip code flash, 640 KB SRAM, and hardware AES-128/192/256 encryption. It integrates Ethernet MAC, dual CAN channels, SD host/slave interfaces, QSPI, GLCDC, DRW2D, and a 12-bit A/D converter with 21-channel input - deployed in industrial HMI, networked gateway controllers, and secure IoT edge nodes.

For engineers reviewing the R5F5651EHDFM#10 datasheet, R5F5651EHDFM#10 pinout, R5F5651EHDFM#10 application, or R5F5651EHDFM#10 equivalent, key selection considerations include its 176-pin LFBGA (PLQP0176KB-A) package, dual-bank flash for safe firmware updates, 120-MHz real-time deterministic execution, and IEC60730-compliant safety features including CRC, IWDT, and register write protection.

Technical Context

The R5F5651EHDFM#10 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 multiply-and-accumulate units plus a 32-bit multiplier (1-cycle) and divider (2-cycle).

Its clock system combines external crystal (8–24 MHz), internal PLL, and selectable on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent clock domains: ICLK (up to 120 MHz for CPU), PCLKA (120 MHz for ETHERC/EDMAC/GLCDC), PCLKB (60 MHz for most peripherals), and dedicated ADCLKs (60 MHz). The MPU enforces eight memory protection areas down to 16-byte granularity.

FAQ

What is the maximum operating frequency and CPU performance of the R5F5651EHDFM#10?

The R5F5651EHDFM#10 operates at a maximum frequency of 120 MHz using the RXv2 CPU core and delivers 240 DMIPS. Its single-precision IEEE-754 FPU, dual MAC units, and 5-stage pipeline enable deterministic real-time computation for industrial control loops and protocol stacks. This performance level is confirmed in Renesas document R01DS0276EJ0240 Rev.2.40, page 1.

Does the R5F5651EHDFM#10 support secure boot and cryptographic acceleration?

Yes, the R5F5651EHDFM#10 includes Trusted Secure IP (TSIP), hardware AES-128/192/256 engines, a CRC calculator supporting multiple polynomials, and Trusted Memory (TM) that restricts code flash access to CPU instruction fetch only. These features collectively enable secure boot, encrypted firmware updates, and TLS offload - all verified in the RX65N Group datasheet section "Encryption functions".

What package type and pin count does the R5F5651EHDFM#10 use?

The R5F5651EHDFM#10 uses the PLQP0176KB-A package: a 176-pin LFBGA with 24 × 24 mm body size and 0.5-mm pitch. It provides 136 general-purpose I/O pins, including 19 with 5-V tolerance, and supports the full peripheral set described for the RX65N Group's 176-pin variants per Table 1.2 in R01DS0276EJ0240.

Can the R5F5651EHDFM#10 drive a color LCD display without external components?

Yes, the R5F5651EHDFM#10 integrates a Graphic-LCD Controller (GLCDC) supporting 3-plane overlay and a 2D Drawing Engine (DRW2D) with bit blitting and vector rendering. It directly drives common RGB parallel LCD panels up to 480×272 resolution using its built-in timing generator and pixel clock - eliminating need for external display controllers or frame buffer RAM.

What safety certifications and features does the R5F5651EHDFM#10 support for industrial compliance?

The R5F5651EHDFM#10 includes hardware features required for IEC60730 Class B compliance: oscillation-stop detection, frequency measurement, CRC calculator (CRCA), independent watchdog timer (IWDT) with windowing, self-diagnostic A/D, and register write protection. These are explicitly documented in the "Useful functions for IEC60730 compliance" section of the RX65N datasheet (R01DS0276EJ0240, page 1).
