Renesas R5F56604BDFN#30

Overview

R5F56604BDFN#30 from Renesas is a 32-bit RXv3 core microcontroller operating at up to 120 MHz, featuring 1 Mbyte on-chip code flash, 128 Kbytes SRAM, and 32 Kbytes data flash. It integrates CAN FD (ISO 11898-1:2015), 12-bit A/D (24 channels), dual 12-bit D/A converters, RTC with sub-clock support, and ELC-based event-driven peripheral coordination - deployed in industrial motor control systems requiring deterministic real-time response and functional safety compliance.

For engineers reviewing the R5F56604BDFN#30 datasheet, R5F56604BDFN#30 pinout, R5F56604BDFN#30 application, or R5F56604BDFN#30 equivalent, key selection criteria include its 144-pin LFQFP package with JTAG/FINE debug support, 2.7–5.5 V single-supply operation, IEC60730-ready self-test features (oscillation-stop detection, RAM test assist, CRC, IWDT), and hardware-accelerated trigonometric functions (TFU) for motion control algorithms.

Technical Context

The R5F56604BDFN#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 16-register bank save/restore for fast context switching in interrupt-heavy applications. Its clock system supports independent domain scaling: ICLK up to 120 MHz for CPU/core logic, PCLKA up to 120 MHz for MTU3a/RSPI/SCI10–11, PCLKB up to 60 MHz for TMR/CMT/CMTW/SCIk, and ADCLK up to 60 MHz for S12ADH - enabling precise timing isolation across analog, control, and communication subsystems.

Peripheral coordination is managed via the Event Link Controller (ELC), which routes 83 internal event signals (e.g., timer compare match, A/D conversion complete, CAN FD reception) directly to target modules without CPU intervention. This enables low-latency, power-efficient operation - such as triggering A/D sampling from MTU3a PWM edges or initiating CAN FD transmission upon external GPIO edge - while the CPU remains in software standby mode.
