Renesas R5F56604CDFP#30

Overview

R5F56604CDFP#30 from Renesas is a 32-bit RXv3 microcontroller designed for industrial control and safety-critical embedded systems, operating at up to 120 MHz with 709 CoreMark performance, 1 Mbyte on-chip code flash, 128 Kbytes SRAM, and integrated CAN FD, 12-bit A/D and D/A converters, RTC, and hardware-based IEC60730 compliance features.

For engineers reviewing the R5F56604CDFP#30 datasheet, R5F56604CDFP#30 pinout, R5F56604CDFP#30 application, or R5F56604CDFP#30 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, dual D/A output capability, sub-clock oscillator support for RTC operation, JTAG/FINE debug interfaces, and full peripheral set including MTU3a timer, ELC, and trusted memory (TM) protection.

Technical Context

The R5F56604CDFP#30 implements the RXv3 CPU core with single-precision FPU compliant with IEEE 754, collective register bank save, and MPU for memory protection. Its clock system integrates main (8–24 MHz crystal), sub (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL for 120 MHz ICLK generation.

Peripheral architecture centers on event-driven operation via the Event Link Controller (ELC), enabling inter-module triggering without CPU intervention. It supports background programming/erasing of both code flash and 32 Kbytes data flash (100,000 write cycles), and includes hardware accelerators for CRC (CRCA), trigonometric functions (TFU), and data operation (DOCA) to offload deterministic real-time tasks.

FAQ

Does the R5F56604CDFP#30 support hardware-based IEC60730 Class B compliance?

Yes, the R5F56604CDFP#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stoppage detection, A/D converter self-diagnosis and disconnection detection, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with window function, RAM test assist via DOC, and CRCA for data integrity. These are documented in the R01DS0393EJ0100 datasheet sections 1.1 and 28.

What is the maximum ADC sampling rate achievable with the R5F56604CDFP#30's S12ADH module?

The R5F56604CDFP#30's S12ADH 12-bit ADC achieves a minimum conversion time of 0.9 µs per channel when ADCLK runs at 60 MHz, enabling up to approximately 1.11 MSPS aggregate throughput across all 24 channels in sequential scan mode. Actual sustained rate depends on channel count, sampling time settings, and trigger source latency - verified in Section 23.3.2 of R01DS0393EJ0100.

Can the R5F56604CDFP#30 operate without an external crystal oscillator?

Yes, the R5F56604CDFP#30 can operate using only on-chip oscillators: the 240 kHz LOCO or selectable HOCO (16/18/20 MHz) as system clock source, with PLL multiplication to reach 120 MHz. However, RTC functionality and CAN FD bit timing accuracy require the 32.768 kHz sub-clock crystal (XT1/XT2) and/or 8–24 MHz main crystal (XTAL/EXTAL) respectively - per Sections 12.1 and 18.1 of R01DS0393EJ0100.

Is the R5F56604CDFP#30 pin-compatible with other RX660 Group devices in the same package?

Yes, all RX660 Group MCUs in the 144-pin LFQFP (PLQP0144KA-B) package - including R5F56604CDFP#30, R5F56605CDFP#30, and R5F566T5ADFP#30 - share identical pinouts and electrical characteristics. Differences are limited to internal configuration (e.g., flash size, peripheral enablement) and do not affect PCB layout - confirmed in Table 1.2 and Figure 1.1 of R01DS0393EJ0100.

Does the R5F56604CDFP#30 support TrustZone or similar ARM-style secure enclave technology?

No, the R5F56604CDFP#30 does not implement ARM TrustZone. Instead, it provides Renesas' Trusted Memory (TM) function, which protects designated code flash regions from unauthorized read access while permitting CPU instruction fetch - combined with MPU-based memory isolation and register write protection for comprehensive firmware security. This approach meets IEC60730 requirements without TrustZone hardware.
