Renesas R5F56604HDFP#30

Overview

R5F56604HDFP#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 (24 ch), 12-bit D/A (2 ch), RTC, and remote control signal receiver - deployed in industrial motor control, building automation gateways, and IEC 60730-compliant appliance controllers.

For engineers reviewing the R5F56604HDFP#30 datasheet, R5F56604HDFP#30 pinout, R5F56604HDFP#30 application, or R5F56604HDFP#30 equivalent, key selection criteria include its 144-pin LFQFP package with JTAG/FINE debug support, sub-clock oscillator inclusion enabling RTC operation, full 2-channel D/A output usable as comparator reference, and CAN FD compliance per ISO 11898-1:2015 for automotive-grade communication.

Technical Context

The R5F56604HDFP#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching. Its clock system integrates main (8–24 MHz crystal), sub (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and fine-grained peripheral clock domain control (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).

Peripheral coordination is managed via the Event Link Controller (ELC), supporting 83 internal event signals for interrupt-free inter-module triggering - e.g., MTU3a PWM edge events initiating A/D conversion or RTC alarm events waking from deep software standby. Safety features include MPU (8 regions), Trusted Memory (TM) for code protection, CRC calculator (CRCA) with selectable polynomials, and hardware-accelerated self-test functions for A/D, RAM, and clock accuracy monitoring.

FAQ

Does the R5F56604HDFP#30 support RTC functionality, and what hardware is required?

Yes, the R5F56604HDFP#30 supports full RTC functionality including calendar, alarm, and time-capture modes. This requires connection of a 32.768 kHz crystal to the XT1/XT2 pins. The device includes a sub-clock oscillator circuit, and RTC operation is disabled if XT1/XT2 are unconnected or if the sub-clock oscillator is omitted in the variant - confirmed by R01DS0393EJ0100 Rev.1.00 Section 1.1 and Table 1.2.

What is the maximum A/D conversion rate achievable with the R5F56604HDFP#30's S12ADH module?

The R5F56604HDFP#30's S12ADH module achieves a minimum conversion time of 0.9 µs per channel when ADCLK runs at 60 MHz, enabling up to ~1.11 MSPS per channel. With 24 input channels and group scan mode, sustained throughput depends on sampling time configuration and trigger source - all verified in R01DS0393EJ0100 Rev.1.00 Section 1.1, Table 1.1.

Is the R5F56604HDFP#30 pin-compatible with other RX660 Group MCUs in the same 144-pin LFQFP package?

Yes, the R5F56604HDFP#30 shares identical pinout and electrical characteristics with other RX660 Group 144-pin LFQFP variants (e.g., R5F56605HDFP#30, R5F566T5HDFP#30) per Renesas' package compatibility documentation. Differences are limited to internal feature enablement (e.g., sub-clock oscillator, flash size) - no PCB layout change is needed for substitution within the same package family.

How does the R5F56604HDFP#30 implement functional safety per IEC 60730?

The R5F56604HDFP#30 integrates hardware safety mechanisms including oscillation-stop detection, A/D disconnection test, clock accuracy measurement (CAC), RAM test assist (DOC), CRC calculator (CRCA), and register write protection - all documented in R01DS0393EJ0100 Rev.1.00 Section 1.1 and Section 27. These features collectively support Class B compliance without external safety monitors.

Can the R5F56604HDFP#30's D/A outputs be used simultaneously as reference voltages for the analog comparators?

Yes, both R12DAb channels (DA0 and DA1) can be configured as reference voltage sources for the four CMPC comparators - explicitly stated in R01DS0393EJ0100 Rev.1.00 Section 1.1, Note 2, and Table 1.1. This enables flexible threshold-setting for overvoltage, undervoltage, or window-comparison protection schemes without external DACs.
