Renesas R5F56604HGFB#30

Overview

R5F56604HGFB#30 from Renesas is a 32-bit RXv3 microcontroller with 120 MHz maximum operating frequency, 1 MB on-chip code flash, 128 KB SRAM, and integrated CAN FD, 12-bit A/D and D/A converters, RTC, and hardware FPU. It operates from a single 2.7–5.5 V supply and supports IEC60730-compliant safety functions for industrial control and motor drive applications.

For engineers reviewing the R5F56604HGFB#30 datasheet, R5F56604HGFB#30 pinout, R5F56604HGFB#30 application, or R5F56604HGFB#30 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, sub-clock oscillator support enabling real-time clock operation, JTAG/FINE debug interfaces, and full peripheral set including MTU3a timers, ELC event linking, and dual-channel 12-bit D/A output usable as comparator reference.

Technical Context

The R5F56604HGFB#30 implements the RXv3 CPU core with IEEE 754-compliant single-precision FPU, 16 register banks for fast context switching, and MPU-based memory protection. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator - all configurable via dedicated registers.

Peripheral coordination is managed by the Event Link Controller (ELC), which enables 83 internal event signals to trigger module actions (e.g., A/D conversion start, timer reset) without CPU intervention - critical for deterministic low-latency response in motor control and safety-critical systems.

FAQ

What is the maximum operating frequency and core architecture of the R5F56604HGFB#30?

The R5F56604HGFB#30 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core. It delivers 709 CoreMark performance and includes a single-precision IEEE 754 floating-point unit (FPU), 16 register banks for fast context switching, and support for both little-endian and big-endian data formats. This architecture enables deterministic real-time execution for motor control and industrial automation tasks.

Does the R5F56604HGFB#30 support real-time clock (RTC) functionality, and what is required to enable it?

Yes, the R5F56604HGFB#30 supports RTC functionality, enabled by its integrated sub-clock oscillator circuit. To operate the RTC, a 32.768 kHz crystal must be connected to the RTCXTAL/RTCXTAL pins. The device's G-version rating (–40°C to +105°C) and deep software standby mode with RTC active make R5F56604HGFB#30 suitable for time-stamped logging and alarm-based wake-up in harsh environments.

What communication interfaces are integrated into the R5F56604HGFB#30, and which support high-speed operation?

The R5F56604HGFB#30 integrates CAN FD (up to 5 Mbps, ISO 11898-1:2015), 13 SCI channels (with LIN, SPI, and I²C emulation), 2 RIIC interfaces (400 kbps fast-mode), 1 RSPId (30 Mbps), and 1 REMCa remote control receiver. Among these, RSPId achieves the highest data rate, while CAN FD provides robust automotive-grade networking - both fully supported in the 144-pin PLQP0144KA-B package of R5F56604HGFB#30.

How does the R5F56604HGFB#30 support functional safety standards such as IEC60730?

The R5F56604HGFB#30 includes multiple hardware features for IEC60730 Class B compliance: oscillation-stop detection, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOCA) for RAM testing, register write protection, and self-diagnostic A/D converter functions. These are documented in the R01DS0393EJ0100 datasheet and enable certified safety firmware implementation without external components.

What is the package type and pin count of the R5F56604HGFB#30, and does it include JTAG debugging support?

The R5F56604HGFB#30 uses a 144-pin LFQFP package (PLQP0144KA-B, 20 × 20 mm, 0.5 mm pitch) and includes full JTAG debugging support alongside the FINE one-wire interface. This dual-debug capability allows comprehensive boundary-scan testing and real-time emulation - essential for development of complex motor control and safety-critical firmware on R5F56604HGFB#30.
