Renesas R5F56604CGFB#30

Overview

R5F56604CGFB#30 from Renesas is a 32-bit RXv3 microcontroller with 120 MHz maximum operating frequency, 1 Mbyte on-chip code flash, 128 Kbytes SRAM, and integrated CAN FD, 12-bit A/D and D/A converters, RTC, and remote control signal receiver - deployed in industrial motor control, building automation gateways, and IEC 60730-compliant appliance controllers.

For engineers reviewing the R5F56604CGFB#30 datasheet, R5F56604CGFB#30 pinout, R5F56604CGFB#30 application, or R5F56604CGFB#30 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, G-grade temperature range (–40°C to +105°C), dual D/A output capability, sub-clock oscillator support for RTC operation, and full JTAG + FINE debugging interface.

Technical Context

The R5F56604CGFB#30 implements the RXv3 CPU core with single-precision FPU, 113 instructions including DSP and floating-point operations, and collective register bank save for fast context switching. It supports little- or big-endian data arrangement and executes instructions at one per system clock cycle up to 120 MHz.

Its clock system integrates main (8–24 MHz crystal), sub (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL-based domain clocks: ICLK (up to 120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), PCLKD (60 MHz), and BCLK (40 MHz) - enabling precise peripheral timing isolation and low-latency event-driven operation via ELC.

FAQ

What is the maximum operating frequency and core architecture of the R5F56604CGFB#30?

The R5F56604CGFB#30 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core with single-precision floating-point unit (FPU), achieving 709 CoreMark. Its architecture supports collective register bank save, memory protection unit (MPU), and IEEE 754-compliant arithmetic - making R5F56604CGFB#30 suitable for deterministic real-time control tasks in industrial environments.

Does the R5F56604CGFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56604CGFB#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with data phase speeds up to 5 Mbps. This enables high-bandwidth communication in automotive and industrial networks - a key differentiator of R5F56604CGFB#30 within the RX660 family.

What are the analog capabilities of the R5F56604CGFB#30, and how are they used in safety-critical systems?

The R5F56604CGFB#30 features a 24-channel 12-bit A/D converter (S12ADH), two 12-bit D/A outputs (R12DAb), and four analog comparators (CMPC). These support self-diagnostic A/D, analog input disconnection detection, and DAC-as-reference functionality - all leveraged in IEC 60730 Class B implementations to validate sensor integrity and actuator response, directly enhancing R5F56604CGFB#30's safety certification readiness.

What package type and thermal grade does the R5F56604CGFB#30 use, and why is this important for industrial deployment?

The R5F56604CGFB#30 uses a 144-pin LFQFP (PLQP0144KA-B) package with 20 × 20 mm footprint and 0.5 mm pitch, rated for the G-grade temperature range of –40°C to +105°C. This wide operating range and robust QFP form factor ensure reliability in enclosed, high-ambient-temperature industrial enclosures - a critical requirement distinguishing R5F56604CGFB#30 from commercial-grade alternatives.

How does the Event Link Controller (ELC) in the R5F56604CGFB#30 improve system efficiency and reduce CPU load?

The ELC in R5F56604CGFB#30 enables direct hardware-level linking of 83 internal event sources - such as timer overflow or A/D completion - to peripheral actions like DMA trigger or GPIO toggle, eliminating interrupt servicing overhead. This allows R5F56604CGFB#30 to maintain ultra-low latency in motor control or sensor acquisition while freeing the CPU for higher-layer tasks.
