Product details
Overview
R5F56317SGFC#V0 from Renesas is a 100 MHz 32-bit RX63N Group microcontroller with integrated Ethernet MAC, single-precision IEEE-754 FPU, 165 DMIPS performance, 768 KB on-chip flash memory, and 128 KB SRAM. It operates from a 2.7–3.6 V supply, supports -40 to +85°C industrial temperature range, and targets networked industrial control, building automation gateways, and embedded HMI systems requiring deterministic real-time response and secure connectivity.
For engineers reviewing the R5F56317SGFC#V0 datasheet, R5F56317SGFC#V0 pinout, R5F56317SGFC#V0 application, or R5F56317SGFC#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), confirmed Ethernet/USB/CAN interface support, and validated alternative part selection guidance for migration and second-sourcing decisions.
Technical Context
The R5F56317SGFC#V0 implements the 32-bit RX CPU core with 5-stage CISC Harvard pipeline, supporting variable-length instructions and ultra-compact code density. It integrates a dedicated Ethernet MAC (10/100 Mbps, MII/RMII), full-speed USB 2.0 host/function/OTG controller, and three CAN modules compliant with ISO11898-1 - all enabled in the RX63N Group but omitted in RX631 variants.
Its memory subsystem includes no-wait-state 100 MHz flash (768 KB), 128 KB SRAM, and 32 KB reprogrammable data flash (100,000 erase/write cycles). Clocking uses external crystal or internal PLL (4–16 MHz input), with independent ICLK (up to 100 MHz), PCLK (up to 50 MHz), and BCLK (up to 50 MHz) domains for precise peripheral timing control.
