Product details
Overview
R5F56316SDFC#V0 from Renesas is a 100 MHz 32-bit RX63N Group microcontroller with integrated Ethernet MAC, single-precision IEEE-754 FPU, 165 DMIPS performance, 1.5 MB on-chip flash memory, and 192 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 IoT edge nodes requiring deterministic real-time response and secure connectivity.
For engineers reviewing the R5F56316SDFC#V0 datasheet, R5F56316SDFC#V0 pinout, R5F56316SDFC#V0 application, or R5F56316SDFC#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), confirmed Ethernet/USB/CAN/SCI peripheral integration, and two validated alternative parts for functional migration paths in industrial embedded designs.
Technical Context
The R5F56316SDFC#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dedicated hardware accelerators including a 32-bit multiplier (1-cycle execution), divider (2-cycle), and AES engine supporting 128/192/256-bit keys in ECB/CBC modes.
Its clock system combines external crystal oscillator support (4–16 MHz), internal 50 MHz HOCO and 125 kHz LOCO, plus PLL-based frequency synthesis for independent ICLK (up to 100 MHz), PCLK (up to 50 MHz), and BCLK (up to 50 MHz) domains - enabling precise timing partitioning across CPU, peripherals, and external bus interfaces.
