Overview

R5F56604HDFP#10 from Renesas is a 32-bit RXv3 microcontroller operating at up to 120 MHz, featuring 1 Mbyte on-chip code flash, 128 Kbytes SRAM, 32 Kbytes data flash, integrated CAN FD, 12-bit A/D and D/A converters, RTC with sub-clock oscillator support, and hardware FPU compliant with IEEE 754. It targets industrial motor control, building automation, and IEC 60730-compliant appliance systems requiring deterministic real-time response and functional safety features.

For engineers reviewing the R5F56604HDFP#10 datasheet, R5F56604HDFP#10 pinout, R5F56604HDFP#10 application, or R5F56604HDFP#10 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package with 130 general-purpose I/O pins (4 × 5-V tolerant), dual 12-bit DAC outputs usable as comparator references, ELC-driven event-triggered peripheral coordination, and support for deep software standby with RTC continuity - all validated in Rev.1.00 of R01DS0393EJ0100.

Technical Context

The R5F56604HDFP#10 implements the RXv3 CPU core with single-cycle instruction execution, 16 × 32-bit general-purpose registers, and hardware single-precision FPU. Its clock system integrates a PLL fed by an 8–24 MHz external crystal, internal HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator, enabling independent domain clocks: ICLK up to 120 MHz, PCLKA up to 120 MHz (for MTU3a, RSPI, SCI10/11), PCLKB up to 60 MHz (for TMRb, CMT, S12ADH), and ADCLK up to 60 MHz.

Peripheral coordination is managed via the Event Link Controller (ELC), supporting 83 internal event signals for CPU-free inter-module triggering - e.g., MTU3a PWM edge events initiating A/D conversion or REMCa pattern detection toggling GPIO pins. Safety-critical operation is reinforced by MPU (8 regions, 16-byte granularity), Trusted Memory (TM) protection for code flash, register write protection, CRC calculator (CRCA) with selectable polynomials, and dedicated clock accuracy monitoring (CAC) for all oscillators.
