Renesas R5F56604EDFB#30

Overview

R5F56604EDFB#30 from Renesas is a 32-bit RXv3 core MCU 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 for event-driven peripheral coordination - deployed in industrial motor control systems requiring deterministic real-time response and functional safety compliance.

For engineers reviewing the R5F56604EDFB#30 datasheet, R5F56604EDFB#30 pinout, R5F56604EDFB#30 application, or R5F56604EDFB#30 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG/FINE debug interface, 2.7–5.5 V single-supply operation, IEC60730-ready self-test features, and full peripheral set including MTU3a (9-channel PWM), RSPId (30 Mbps SPI), and RIICa (400 kbps I²C).

Technical Context

The R5F56604EDFB#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 16-register bank save for fast context switching. Its clock system combines an 8–24 MHz external main oscillator, 32.768 kHz sub-clock, and selectable on-chip HOCO/LOCO sources feeding a PLL to achieve 120 MHz ICLK while supporting independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz, ADCLK up to 60 MHz).

Peripheral coordination is managed via the Event Link Controller (ELC), which enables 83 internal event signals to trigger module actions (e.g., MTU3a capture, S12ADH conversion, or R12DAb output update) without CPU intervention - critical for low-latency deterministic operation in motor drive and power conversion applications where interrupt latency must be minimized.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604EDFB#30?

The R5F56604EDFB#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark under those conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, barrel shifter, and integrated FPU - all validated per Renesas R01DS0393EJ0100 Rev.1.00, Section 1.1. The R5F56604EDFB#30 sustains this speed with zero wait states on both 1 Mbyte code flash and 128 Kbytes SRAM.

Does the R5F56604EDFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56604EDFB#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It operates at data rates up to 5 Mbps in FD mode and includes bit-rate switching, flexible data-length payloads (up to 64 bytes), and error confinement - confirmed in Section 1.1, Table 1.1 and Section 22 of the R01DS0393EJ0100 datasheet. The R5F56604EDFB#30 uses this for real-time diagnostics and firmware updates in industrial networks.

What debug interfaces are available on the R5F56604EDFB#30?

The R5F56604EDFB#30 supports both JTAG (IEEE 1149.1) and FINE (Renesas' one-wire debug interface) for on-chip debugging and programming. JTAG enables full boundary-scan, real-time tracing, and multi-core debug; FINE provides minimal-pin debugging ideal for space-constrained layouts. Both are documented in Section 1.1 and Figure 1.2 of R01DS0393EJ0100. The R5F56604EDFB#30 requires no external debug probe for basic FINE use, reducing development tooling cost.

How many A/D and D/A converter channels does the R5F56604EDFB#30 include?

The R5F56604EDFB#30 includes one 12-bit S12ADH analog-to-digital converter with 24 input channels and two independent 12-bit R12DAb digital-to-analog converters. Each R12DAb channel outputs 0 V to AVCC0 and can serve as a reference voltage for the four-channel CMPC analog comparator - verified in Sections 1.1 (Table 1.1), 19 (S12ADH), and 20 (R12DAb) of R01DS0393EJ0100. This configuration supports closed-loop analog signal conditioning in the R5F56604EDFB#30.

What low-power modes and RTC capabilities does the R5F56604EDFB#30 offer?

The R5F56604EDFB#30 supports four low-power modes - sleep, all-module clock stop, software standby, and deep software standby - with RTC continuing to run in deep software standby using the 32.768 kHz sub-clock oscillator. RTC features include binary/BCD time counting, alarm/periodic interrupts, time capture on external events, and leap-year adjustment. These functions require the sub-clock oscillator (XTAL/EXTAL pins), as specified in Sections 1.1 and 26 of R01DS0393EJ0100. The R5F56604EDFB#30 leverages this for time-critical wake-up and energy-efficient operation.
