Overview
R5F56517EGLK#20 from Renesas is a 32-bit RXv2 microcontroller with 120 MHz max operating frequency, 240 DMIPS performance, on-chip FPU compliant with IEEE-754 single-precision, 2 MB code flash memory (dual-bank), and 640 KB SRAM - designed for industrial HMI, networked gateway, and secure embedded control applications requiring Ethernet MAC, CAN, SD host/slave, and GLCDC support.
For engineers reviewing the R5F56517EGLK#20 datasheet, R5F56517EGLK#20 pinout, R5F56517EGLK#20 application, or R5F56517EGLK#20 equivalent, this MCU delivers deterministic real-time execution, IEC60730-compliant safety features including CRC, IWDT, and register write protection, plus hardware-accelerated AES-128/192/256 and TSIP for secure boot and firmware updates.
Technical Context
The R5F56517EGLK#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual-clock domain operation: ICLK up to 120 MHz for CPU and PCLKA-synchronized peripherals (ETHERC, EDMAC, AES, GLCDC), and PCLKB up to 60 MHz for analog and timing modules including S12AD units and MTU3 timers.
Its peripheral set includes an integrated Ethernet MAC (10/100 Mbps, MII/RMII), two CAN channels (ISO 11898-1, 32 mailboxes each), three RSPI interfaces, quad SPI, three I²C buses (one supporting 1 Mbps fast-mode plus), SDHI/SDSI/MMCIF controllers, and a full-featured graphic-LCD controller (GLCDC) with 2D drawing engine (DRW2D) - all coordinated via the Event Link Controller (ELC) for zero-CPU-intervention signal chaining.
