For engineers reviewing the R5F56604DDFN#30 datasheet, R5F56604DDFN#30 pinout, R5F56604DDFN#30 application, or R5F56604DDFN#30 equivalent, key selection criteria include verified 120-MHz operation with no wait states, 144-pin LFQFP (PLQP0144KA-B) package compatibility, integrated CAN FD compliance per ISO 11898-1:2015, dual 12-bit DAC outputs usable as comparator references, and full ELC event-linking capability for low-CPU-overhead peripheral coordination.

Technical Context

The R5F56604DDFN#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, 16 register banks for fast context switching, and MPU-based memory protection across eight configurable regions. It integrates a dedicated 120-kHz IWDT oscillator and supports deep software standby with RTC retention.

Its clock system combines an 8–24 MHz external main oscillator, 32.768 kHz sub-clock for RTC, and selectable on-chip oscillators (LOCO/HOCO), with independent frequency division for ICLK (up to 120 MHz), PCLKA (up to 120 MHz), PCLKB (up to 60 MHz), and ADCLK (up to 60 MHz). The MTU3a timer unit delivers complementary PWM with programmable dead time for 3-phase inverter control.

FAQ

What is the maximum operating frequency and flash access performance of the R5F56604DDFN#30?

The R5F56604DDFN#30 operates at a maximum frequency of 120 MHz with zero wait states for both code flash and SRAM access. Its 512 KB on-chip code flash supports full-speed execution at this rate, enabling deterministic real-time response critical for motor control and industrial automation. This eliminates instruction fetch bottlenecks seen in lower-tier MCUs, and the R5F56604DDFN#30 achieves 709 CoreMark at 120 MHz - validating sustained computational throughput.

Does the R5F56604DDFN#30 support CAN FD, and what standard compliance does it meet?

Yes, the R5F56604DDFN#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frame formats with bit rates up to 5 Mbps in FD mode. It requires an external CAN transceiver for physical layer interfacing. The R5F56604DDFN#30's CAN FD implementation includes hardware message filtering, TX/RX FIFOs, and error counters - making it suitable for high-bandwidth industrial networking where legacy CAN 2.0B is insufficient.

How many analog-to-digital and digital-to-analog converter channels does the R5F56604DDFN#30 include?

The R5F56604DDFN#30 includes one 12-bit S12ADH analog-to-digital converter with 24 input channels and two 12-bit R12DAb digital-to-analog converter channels. Each DAC output can be routed as a reference voltage to any of the four analog comparators (CMPC), enabling flexible threshold-based monitoring. The R5F56604DDFN#30's ADC achieves 0.9 µs conversion time at 60 MHz ADCLK, supporting high-speed sampling in closed-loop control systems.

What low-power modes are available on the R5F56604DDFN#30, and which retain RTC functionality?

The R5F56604DDFN#30 supports four low-power modes: Sleep, All-Module Clock Stop, Software Standby, and Deep Software Standby. Only Deep Software Standby retains RTC operation - powered by the 32.768 kHz sub-clock oscillator - allowing time-stamped wake-up events while drawing sub-µA current. The R5F56604DDFN#30 requires the XTAL/EXTAL pins populated and the sub-clock oscillator enabled to use this mode, as confirmed in the hardware manual section 27.6.7.

Is the R5F56604DDFN#30 pin-compatible with other RX660 Group MCUs in the same package?

Yes, the R5F56604DDFN#30 is pin-compatible with other 144-pin LFQFP RX660 Group variants (e.g., R5F56605DDFN#30, R5F56603DDFN#30) sharing the PLQP0144KA-B package. All share identical pin assignments for power, reset, clocks, JTAG/FINE, and peripheral I/O. Differences lie in internal configuration (e.g., sub-clock oscillator presence, flash size), not pin function - enabling drop-in replacement where firmware and BOM constraints align with the selected variant's feature set.
