Renesas R5F56604ADFB#30

Overview

R5F56604ADFB#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 R5F56604ADFB#30 datasheet, R5F56604ADFB#30 pinout, R5F56604ADFB#30 application, or R5F56604ADFB#30 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, dual D/A output capability, sub-clock oscillator support for RTC operation, JTAG+FINE debug interface, and full CAN FD compliance per ISO 11898-1:2015.

Technical Context

The R5F56604ADFB#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16 register banks for fast context switching. It integrates an event link controller (ELC) enabling interrupt-free inter-module triggering - critical for deterministic real-time response in motor control loops.

Its clock system combines a 8–24 MHz main crystal oscillator, 32.768 kHz sub-clock for RTC, and multiple on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PCLKA (up to 120 MHz), PCLKB (up to 60 MHz), and ADCLK (up to 60 MHz) domains - allowing precise peripheral timing isolation for mixed-signal applications.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F56604ADFB#30?

The R5F56604ADFB#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, 113 instructions, and collective register bank save functionality. This architecture enables deterministic real-time execution for motor control and safety-critical tasks in the R5F56604ADFB#30.

Does the R5F56604ADFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56604ADFB#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. Its CANFD peripheral includes message filtering, FIFO buffering, and error handling logic - enabling robust communication in automotive and industrial networks without external transceivers beyond physical layer drivers. This capability is fully implemented in the R5F56604ADFB#30.

What analog peripherals are integrated into the R5F56604ADFB#30?

The R5F56604ADFB#30 integrates a 24-channel 12-bit S12ADH ADC (0.9 µs min conversion time), two 12-bit R12DAb DAC channels (0–AVCC0 output), four CMPC analog comparators, and an on-die temperature sensor (±1.0°C). The DAC outputs can serve as comparator references, and the ADC includes self-diagnostic and analog input disconnection detection - all confirmed features of the R5F56604ADFB#30.

Is the real-time clock (RTC) functional in the R5F56604ADFB#30, and what clock source does it require?

Yes, the RTC in the R5F56604ADFB#30 is fully functional and requires the sub-clock oscillator (SOSC) connected to a 32.768 kHz crystal on RTCXTAL/RTCXTAL pins. The R5F56604ADFB#30 is specified with SOSC support in its 144-pin LFQFP configuration, enabling calendar mode, time capture, and alarm interrupts - unlike variants without SOSC. This RTC capability is a defined feature of the R5F56604ADFB#30.

What debugging interfaces does the R5F56604ADFB#30 support, and are they accessible in the 144-pin package?

The R5F56604ADFB#30 supports both JTAG and FINE (single-wire) debugging interfaces, and both are fully accessible in its 144-pin LFQFP (PLQP0144KA-B) package. JTAG pins (TMS, TDI, TDO, TCK) enable full boundary-scan, flash programming, and real-time trace, while FINE provides minimal-pin debugging - giving developers flexible in-circuit debug options for the R5F56604ADFB#30.
