Product details
Overview
R5F56317CDLK#U0 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 and IoT edge nodes requiring deterministic real-time response and secure connectivity.
For engineers reviewing the R5F56317CDLK#U0 datasheet, R5F56317CDLK#U0 pinout, R5F56317CDLK#U0 application, or R5F56317CDLK#U0 equivalent, this MCU delivers verified Ethernet MAC (10/100 Mbps MII/RMII), full-speed USB 2.0 host/function/OTG, three CAN channels (ISO 11898-1), 13 SCI interfaces, four I²C buses (1 Mbps), and hardware AES encryption - all in a 145-pin TFLGA package with 5-V-tolerant I/O and 133 general-purpose pins.
Technical Context
The R5F56317CDLK#U0 implements the 32-bit RX CPU core with 5-stage CISC Harvard pipeline, variable-length instructions, and memory protection unit (MPU). It integrates dedicated DMA controllers (DMAC, EXDMAC, DTC) and a dedicated EDMAC for Ethernet offloading, enabling zero-copy frame handling at line rate.
Its clock system combines external crystal oscillator support (4–16 MHz), internal PLL, 50-MHz HOCO, and 125-kHz LOCO for independent IWDT operation. The peripheral set includes MTU2 and TPU timers for PWM generation and encoder interfacing, dual A/D converters (21×12-bit + 8×10-bit), two 10-bit D/A channels, and a precision ±1°C on-die temperature sensor.
