Product details
Overview
R5F56517BGLK#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 (no wait states), single-precision IEEE-754 FPU, Ethernet MAC, dual CAN 2.0B channels, SD host/slave interfaces, 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 R5F56517BGLK#20 datasheet, R5F56517BGLK#20 pinout, R5F56517BGLK#20 application, or R5F56517BGLK#20 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), 120-MHz deterministic real-time performance, integrated GLCDC + DRW2D for embedded GUIs, dual-bank flash for safe OTA updates, and IEC60730-compliant safety features including CRC, IWDT, and register write protection.
Technical Context
The R5F56517BGLK#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual-bank flash supporting background programming and bank-swapping during execution - critical for fail-safe firmware updates in field-deployed equipment.
Its peripheral subsystem includes an Ethernet MAC with RMII/MII support, two independent CAN controllers (32 mailboxes each), and a full-featured SDIO stack (SDHI/SDSI/MMCIF) enabling direct interfacing with SD cards, Wi-Fi modules, and eMMC storage - all synchronized to dedicated PCLK domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz) for deterministic timing control.
