For engineers reviewing the R5F56317CDFC#V0 datasheet, R5F56317CDFC#V0 pinout, R5F56317CDFC#V0 application, or R5F56317CDFC#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), confirmed Ethernet/USB/CAN peripheral integration, and two validated alternative parts for functional migration paths in production designs.

Technical Context

The R5F56317CDFC#V0 implements the RXv1 CPU core with 5-stage CISC Harvard pipeline, variable-length instructions, and hardware MPU for memory protection. Its clock system combines external crystal oscillator support (4–16 MHz), internal PLL, and dedicated 125-kHz LOCO for IWDT - enabling precise timing control across system clock (ICLK up to 100 MHz), peripheral clock (PCLK up to 50 MHz), and external bus clock (BCLK up to 50 MHz).

Peripheral architecture includes a dedicated EDMAC for Ethernet offloading, dual USB 2.0 modules (host/function + function-only), three CAN channels compliant with ISO11898-1, and dual A/D converters (21×12-bit + 8×10-bit) with sample-and-hold and conversion trigger flexibility via MTU2/TPU/TMR timers or external signals.
