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 R5F56317DGFC#V0 datasheet, R5F56317DGFC#V0 pinout, R5F56317DGFC#V0 application, or R5F56317DGFC#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 design flexibility in industrial embedded systems.
Technical Context
The R5F56317DGFC#V0 implements the RX CPU core with 5-stage CISC Harvard pipeline, variable-length instructions, and memory protection unit (MPU) for safety-critical execution. It integrates dedicated DMA controllers-including EXDMAC for TFT LCD transfer and EDMAC for Ethernet offload-enabling concurrent high-bandwidth data movement without CPU intervention.
Its clock system combines external crystal oscillator support (4–16 MHz), internal 50 MHz HOCO and 125 kHz LOCO, and programmable PLL for independent ICLK (up to 100 MHz), PCLK (up to 50 MHz), and BCLK (up to 50 MHz) domains. The device includes hardware CRC calculator, AES-128/192/256 DEU, and IEC60730-compliant self-diagnostic features including A/D converter diagnostics and oscillation-stop detection.
