Overview

R5F56517EGLJ#20 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 120 MHz (240 DMIPS), featuring 1.5 MB on-chip code flash, 640 KB SRAM (including 8 KB standby RAM), single-precision IEEE-754 FPU, Ethernet MAC, dual CAN channels, SD host/slave interfaces, and hardware AES-128/192/256 encryption - deployed in industrial HMI, networked gateway, and secure IoT edge node applications.

For engineers reviewing the R5F56517EGLJ#20 datasheet, R5F56517EGLJ#20 pinout, R5F56517EGLJ#20 application, or R5F56517EGLJ#20 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual-bank flash for safe firmware updates, integrated GLCDC + DRW2D for embedded graphics, and IEC60730-compliant safety features including CRC, IWDT, and register write protection.

Technical Context

The R5F56517EGLJ#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling ultra-compact code density and deterministic interrupt latency. It integrates dedicated clock domains: ICLK up to 120 MHz for CPU execution, PCLKA up to 120 MHz for high-speed peripherals (ETHERC, EDMAC, AES, GLCDC), and PCLKB up to 60 MHz for timers and ADCs.

Its memory subsystem includes dual-bank flash supporting background programming and bank-swapping during runtime, 32 KB data flash rated for 100,000 erase/write cycles, and 640 KB SRAM with no wait states at full speed. Peripheral coherency is managed via Event Link Controller (ELC), enabling direct inter-module triggering without CPU intervention - critical for real-time control and low-latency sensor-to-actuator paths.

FAQ

What is the maximum operating frequency and performance rating of the R5F56517EGLJ#20?

The R5F56517EGLJ#20 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS (Dhrystone MIPS) performance. Its RXv2 CPU core includes a single-precision IEEE-754 floating-point unit, 32-bit multiplier (1-cycle), and divider (2-cycle), enabling deterministic real-time computation for industrial control and signal processing tasks within the R5F56517EGLJ#20.

Does the R5F56517EGLJ#20 support secure firmware updates?

Yes, the R5F56517EGLJ#20 supports secure firmware updates via its dual-bank flash architecture and Trusted Memory (TM) function. The TM feature prevents unauthorized read-out of code stored in designated flash areas, while background programming (BGO) allows one bank to execute while the other is reprogrammed - ensuring zero-downtime updates in the R5F56517EGLJ#20.

What display interfaces does the R5F56517EGLJ#20 integrate?

The R5F56517EGLJ#20 integrates a full-featured Graphic-LCD Controller (GLCDC) supporting RGB parallel output up to 24-bit color, plus a dedicated 2D Drawing Engine (DRW2D) for hardware-accelerated bit blitting, rotation, and vector rendering. These peripherals eliminate the need for external graphics ICs and enable responsive UIs in industrial HMIs using the R5F56517EGLJ#20.

How many CAN channels does the R5F56517EGLJ#20 provide, and what standards do they meet?

The R5F56517EGLJ#20 provides two independent CAN modules, each compliant with ISO 11898-1 (Classical CAN) and supporting up to 32 mailboxes per channel. Both channels operate at bit rates up to 1 Mbps and include message filtering, FIFO buffering, and loopback self-test modes - essential for robust fieldbus integration in the R5F56517EGLJ#20.

Is the R5F56517EGLJ#20 qualified for industrial temperature operation?

Yes, the R5F56517EGLJ#20 is rated for industrial temperature operation from –40°C to +85°C (D-version). It includes a calibrated on-die temperature sensor (±1°C accuracy) and supports battery-backed RTC and standby RAM retention - ensuring reliable functionality across harsh environments typical of factory automation and outdoor infrastructure where the R5F56517EGLJ#20 is deployed.
