For engineers reviewing the R5F56609CDFP#10 datasheet, R5F56609CDFP#10 pinout, R5F56609CDFP#10 application, or R5F56609CDFP#10 equivalent, this page delivers verified specifications, package mapping to PLQP0144KA-B (144-pin LFQFP), functional pin roles, IEC 60730 self-test features, CAN FD protocol conformance per ISO 11898-1:2015, and validated alternative MCUs for migration paths.

Technical Context

The R5F56609CDFP#10 implements the RXv3 CPU core with single-precision FPU compliant with IEEE 754, supporting 113 instructions including DSP and floating-point operations. It integrates an event link controller (ELC) enabling interrupt-free inter-module triggering - critical for low-latency motor control loops and real-time sensor fusion.

Its clock system combines a 8–24 MHz main crystal oscillator, 32.768 kHz sub-clock for RTC, and on-chip HOCO/LOCO oscillators with PLL multiplication to achieve 120 MHz ICLK. Peripheral clocks are independently configurable: PCLKA up to 120 MHz (MTU3a, RSPI), PCLKB up to 60 MHz (TMRb, CMT), and ADCLK up to 60 MHz for the S12ADH A/D converter.
