For engineers reviewing the R5F56604CDFM#30 datasheet, R5F56604CDFM#30 pinout, R5F56604CDFM#30 application, or R5F56604CDFM#30 equivalent, key selection criteria include CAN FD compliance (ISO 11898-1:2015), 144-pin LFQFP package with sub-clock oscillator and JTAG interface, 2.7–5.5 V single-supply operation, IEC60730 safety support, and real-time clock functionality requiring external 32.768 kHz crystal.

Technical Context

The R5F56604CDFM#30 implements the RXv3 CPU core with single-precision FPU compliant to IEEE 754, supporting 709 CoreMark at 120 MHz and collective register bank save for fast context switching. It integrates an MPU for memory protection and Trusted Memory (TM) to secure firmware in code flash.

Its clock system combines main (8–24 MHz crystal), sub-clock (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and multi-domain clock gating (ICLK up to 120 MHz, PCLKA/B/D at up to 120/60/60 MHz). The ELC enables interrupt-free inter-module event linking - critical for deterministic timing in motor control and safety-critical functions.
