It targets industrial networking gateways requiring deterministic real-time control and secure wired connectivity.
For engineers reviewing the R5F56317CDFB#V0 datasheet, R5F56317CDFB#V0 pinout, R5F56317CDFB#V0 application, or R5F56317CDFB#V0 equivalent, key selection criteria include Ethernet MAC support (MII/RMII), 100 MHz CPU performance (165 DMIPS), integrated DEU for AES-128/192/256, RTC with battery backup, and compliance with IEC60730 functional safety requirements.
Technical Context
The R5F56317CDFB#V0 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dedicated peripherals including an Ethernet controller (ETHERC) with 2 KB TX/RX FIFOs and EDMAC, USB 2.0 host/function/OTG module, three CAN channels (ISO 11898-1), and four I²C interfaces (one FM+).
Its clock system combines external crystal oscillator (4–16 MHz), internal PLL, 50-MHz HOCO, and 125-kHz LOCO for independent domain control (ICLK up to 100 MHz, PCLK up to 50 MHz). Power management includes four low-power modes, RTC operation down to 2.3 V on VBATT, and module stop functionality for dynamic power gating.
