It integrates CAN FD (ISO 11898-1:2015), 12-bit A/D (24 channels), dual 12-bit D/A, RTC with sub-clock support, and operates from 2.7–5.5 V in industrial temperature range (–40°C to +85°C) for motor control and industrial automation systems.

For engineers reviewing the R5F56604DGFN#30 datasheet, R5F56604DGFN#30 pinout, R5F56604DGFN#30 application, or R5F56604DGFN#30 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG/FINE debug interfaces, integrated FPU, ELC event-driven peripheral coordination, and IEC60730 safety features including MPU, CAC, CRCA, and register write protection.

Technical Context

The R5F56604DGFN#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching. Its clock system supports independent domain scaling: ICLK up to 120 MHz, PCLKA up to 120 MHz (for MTU3a/RSPI/SCI10–11), PCLKB up to 60 MHz (for TMR/CMT/CMTW/S12ADH), and ADCLK up to 60 MHz.

Peripheral integration centers on deterministic real-time operation: ELC enables interrupt-free inter-module triggering (e.g., MTU3a output capture → S12ADH conversion start), DMACAa provides 8-channel DMA with background operation, and the CAN FD module supports both standard and extended frames at data rates up to 5 Mbps. The device includes hardware safety mechanisms - MPU (8 regions, 16-byte granularity), Trusted Memory (TM) for code protection, and dedicated IWDT with windowed refresh and LOCO-derived 120-kHz clock.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604DGFN#30?

The R5F56604DGFN#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32-bit multiplier/divider, barrel shifter, and integrated FPU - all validated per the official Renesas R01DS0393EJ0100 datasheet Rev.1.00. The R5F56604DGFN#30 sustains this performance across its full industrial temperature range (–40°C to +85°C) with no wait states on code flash or SRAM.

Does the R5F56604DGFN#30 support CAN FD, and what protocol standard does it comply with?

Yes, the R5F56604DGFN#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats at data rates up to 5 Mbps. It includes dedicated message RAM, flexible bit timing configuration, and error handling consistent with the standard. This capability is confirmed in Table 1.1 and Section 1.1 of the R01DS0393EJ0100 datasheet, and the R5F56604DGFN#30 implements the full CAN FD feature set without requiring external transceivers.

What package type and pin count does the R5F56604DGFN#30 use?

The R5F56604DGFN#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with designation PLQP0144KA-B: 20 mm × 20 mm body, 0.5 mm lead pitch, and exposed thermal pad. This package supports all RX660 Group features including JTAG/FINE debug, sub-clock oscillator, and full 134 GPIO capability (130 I/O pins with JTAG + sub-clock enabled). The package is explicitly listed in Table 1.1 and Figure 1.1 of the R01DS0393EJ0100 datasheet.

How much on-chip memory does the R5F56604DGFN#30 include, and what are its access characteristics?

The R5F56604DGFN#30 includes 1 MB of code flash memory with zero-wait-state access at 120 MHz, 128 KB of SRAM with zero-wait-state access, and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. All memory blocks support background programming/erasing (BGO), enabling concurrent execution and non-disruptive firmware updates. These specifications are detailed in Sections 1.1 and Table 1.1 of the R01DS0393EJ0100 datasheet, and apply specifically to the R5F56604DGFN#30 variant.

What safety and reliability features does the R5F56604DGFN#30 provide for IEC60730 compliance?

The R5F56604DGFN#30 includes hardware-assisted IEC60730 Class B compliance features: memory protection unit (MPU), Trusted Memory (TM) for code protection, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOCA) for RAM testing, register write protection, and independent watchdog timer (IWDT) with windowed refresh. These are documented in Section 1.1 "Safety" of the R01DS0393EJ0100 datasheet and are implemented in silicon - not software libraries - ensuring deterministic runtime verification for the R5F56604DGFN#30.
