Renesas R5F56604ADFP#30

Overview

R5F56604ADFP#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 remote control signal receiver - deployed in industrial HMI, motor control gateways, and IEC 60730-compliant appliance controllers.

For engineers reviewing the R5F56604ADFP#30 datasheet, R5F56604ADFP#30 pinout, R5F56604ADFP#30 application, or R5F56604ADFP#30 equivalent, key selection criteria include 144-pin LFQFP package compatibility, sub-clock oscillator inclusion for RTC operation, JTAG debugging support, and full CAN FD compliance per ISO 11898-1:2015.

Technical Context

The R5F56604ADFP#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 ELC (Event Link Controller) enabling interrupt-free inter-module triggering across MTU3a timers, S12ADH ADC, and CANFD - critical for deterministic real-time response in motor control loops.

Its clock system combines a 8–24 MHz external main oscillator (PLL-referenced), 32.768 kHz sub-clock for RTC, and dedicated 120 kHz IWDT oscillator. Power management includes four low-power modes with deep software standby retaining RTC operation - supported by dual voltage monitors (LVDA/LVDB) and POR circuitry meeting IEC 60730 Class B requirements.

FAQ

Does R5F56604ADFP#30 support CAN FD with ISO 11898-1:2015 compliance?

Yes, R5F56604ADFP#30 integrates a fully compliant CAN FD module supporting both standard and extended frames per ISO 11898-1:2015. It operates at up to 5 Mbps in the data phase and includes built-in bit-rate switching, error confinement, and message buffering - confirmed in the R01DS0393EJ0100 datasheet section 1.1 and Table 1.1. The R5F56604ADFP#30 requires external CAN transceiver for physical layer interfacing.

What is the exact package type and pin count for R5F56604ADFP#30?

R5F56604ADFP#30 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body size, 0.5 mm lead pitch, and exposed thermal pad. This matches the "144-pin LFQFP with JTAG interface and sub-clock oscillator" configuration described in Table 1.2 of the R01DS0393EJ0100 datasheet, providing 130 general-purpose I/O pins plus dedicated power, clock, and debug signals.

Is the RTC function available on R5F56604ADFP#30, and what conditions enable it?

Yes, the RTC is available on R5F56604ADFP#30, but only when the sub-clock oscillator (SOSC) is enabled and connected to a 32.768 kHz crystal - as specified in Note 1 on page 9 of R01DS0393EJ0100. The R5F56604ADFP#30 includes SOSC pins (XTAL/EXTAL), confirming RTC capability. If unused, registers must be initialized per Section 27.6.7 of the Hardware User's Manual to prevent unintended behavior.

How many independent 12-bit D/A converter channels does R5F56604ADFP#30 provide?

R5F56604ADFP#30 provides two independent 12-bit D/A converter channels (R12DAb), each with dedicated output pins (DA0 and DA1). Both channels support 0 V to AVCC0 output range and can serve as reference voltages for the 4-channel analog comparators (CMPC) - as confirmed in Table 1.2 and section "12-bit D/A converter (R12DAb)" on page 8 of R01DS0393EJ0100.

Does R5F56604ADFP#30 include hardware floating-point support, and what standard does it follow?

Yes, R5F56604ADFP#30 includes a single-precision (32-bit) hardware floating-point unit (FPU) compliant with the IEEE 754 standard. The FPU supports addition, subtraction, multiplication, division, square root, and conversions - enabling efficient computation of trigonometric, exponential, and control algorithms without software emulation overhead. This is documented in Table 1.1 (page 2) and section "FPU" of the R01DS0393EJ0100 datasheet.
