Renesas R5F56517EDFB#10

Overview

R5F56517EDFB#10 from Renesas is a 120-MHz 32-bit RXv2 core MCU with single-precision IEEE-754 FPU, 240 DMIPS performance, 2 MB on-chip code flash (dual-bank), 640 KB SRAM, and integrated Ethernet MAC, CAN, SD host/slave, QSPI, and GLCDC for industrial HMI and connected gateway applications.

For engineers reviewing the R5F56517EDFB#10 datasheet, R5F56517EDFB#10 pinout, R5F56517EDFB#10 application, or R5F56517EDFB#10 equivalent, this device supports IEC60730-compliant safety functions, real-time clock with battery backup, 12-bit dual A/D converters (29 total channels), AES-128/192/256 encryption, and TSIP secure IP - critical for certified industrial control and edge-node designs.

Technical Context

The R5F56517EDFB#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) supporting eight configurable regions. It executes at 120 MHz with zero-wait access to flash up to 50 MHz (or when ROM cache hits), one-wait up to 100 MHz, and two-wait above 100 MHz.

Its clock system integrates PLL, external crystal oscillator (8–24 MHz), and internal oscillators (LOCO at 120 kHz, HOCO at 16/18/20 MHz). Peripheral clocks are independently configurable: PCLKA (up to 120 MHz for ETHERC, GLCDC, DRW2D), PCLKB (up to 60 MHz for most timers and interfaces), and dedicated ADCLKs (PCLKC/PCLKD) for dual 12-bit A/D units.

FAQ

What is the maximum operating frequency and core architecture of the R5F56517EDFB#10?

The R5F56517EDFB#10 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core, delivering 240 DMIPS performance. Its CISC Harvard architecture features a 5-stage pipeline, variable-length instructions, and support for IEEE-754 single-precision floating-point operations - enabling deterministic real-time execution for industrial control algorithms.

Does the R5F56517EDFB#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F56517EDFB#10 includes multiple hardware features required for IEC60730 Class B certification: oscillation-stop detection, CRC calculator (CRCA), independent watchdog timer (IWDT) with window function, A/D converter self-diagnostic capability, and register write protection. These are implemented in silicon and documented in Renesas' functional safety manual for the RX65N Group.

What graphics capabilities does the R5F56517EDFB#10 provide for HMI development?

The R5F56517EDFB#10 integrates a Graphic-LCD Controller (GLCDC) supporting up to 3 overlay planes and a 2D Drawing Engine (DRW2D) with vector drawing, bit blitting, rotation, and texture mapping. It supports 32-/16-bpp graphics and CLUT formats, enabling smooth UI rendering without external graphics ICs - verified in Renesas' GR-SAKURA and DK-RA65N reference designs.

Can the R5F56517EDFB#10 execute firmware updates in the field without interrupting operation?

Yes, the R5F56517EDFB#10 supports seamless firmware updates via its dual-bank flash architecture. While one bank executes active code, the other can be reprogrammed in background (BGO), and startup bank selection is switched via register write - enabling zero-downtime updates confirmed in Renesas Application Note R01AN3813JJ0100.

What is the temperature range and package type for the R5F56517EDFB#10?

The R5F56517EDFB#10 is specified for industrial operation from –40°C to +85°C (D-version) and uses the PLQP0176KB-A package: a 176-pin LFBGA with 24 × 24 mm footprint and 0.5-mm pitch. This package provides 136 general-purpose I/O pins, including 19 with 5-V tolerance, and supports high-density PCB layouts for compact HMI and gateway modules.
