For engineers reviewing the R5F56604ADFN#30 datasheet, R5F56604ADFN#30 pinout, R5F56604ADFN#30 application, or R5F56604ADFN#30 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, 2.7–5.5 V single-supply operation, deep software standby mode with RTC persistence, dual 12-bit DAC outputs usable as comparator references, and support for event-linked peripheral coordination without CPU intervention.

Technical Context

The R5F56604ADFN#30 implements the RXv3 CPU core with single-precision FPU compliant with IEEE 754, collective register bank save, and MPU-based memory protection. Its clock system integrates main (8–24 MHz crystal), sub-clock (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and frequency-division paths for ICLK (up to 120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), and ADCLK (60 MHz).

Peripheral coordination is managed via the Event Link Controller (ELC), enabling 83 internal event signals to trigger timer operations, A/D conversions, or GPIO state changes without interrupt overhead. The MCU supports background programming/erasing of both code flash and 32 Kbytes of data flash (rated for 100,000 cycles), and includes hardware-accelerated CRC (CRCA), trigonometric functions (TFU), and safety features including oscillation-stop detection, RAM test assist (DOC), and register write protection.

FAQ

What is the maximum operating frequency and core architecture of the R5F56604ADFN#30?

The R5F56604ADFN#30 operates at a maximum system clock frequency of 120 MHz using the 32-bit RXv3 CPU core. It includes a single-precision floating-point unit compliant with IEEE 754, delivers 709 CoreMark performance, and supports collective register bank save and memory protection unit (MPU) functionality. This architecture enables deterministic real-time execution in demanding industrial control applications.

Does the R5F56604ADFN#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56604ADFN#30 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frame formats. It enables data rates up to 5 Mbps in the flexible data-rate phase, with built-in message filtering, FIFO buffering, and error handling-making it suitable for modern industrial networked systems requiring higher bandwidth than classical CAN.

What are the analog capabilities of the R5F56604ADFN#30, particularly regarding ADC and DAC?

The R5F56604ADFN#30 features a 24-channel 12-bit S12ADH ADC with minimum 0.9 µs conversion time at 60 MHz ADCLK, plus self-diagnostic and analog input disconnection detection. It also includes two 12-bit R12DAb DAC channels with 0–AVCC0 output range, each usable as a programmable reference voltage for the four-channel CMPC analog comparators-enabling closed-loop sensor conditioning without external components.

How does the R5F56604ADFN#30 support functional safety standards like IEC60730?

The R5F56604ADFN#30 includes multiple hardware safety features for IEC60730 Class B compliance: oscillation-stoppage detection, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDTa) with windowing, RAM test assist (DOC), CRC calculator (CRCA), and register write protection. These reduce software certification burden and enable robust self-test capability in appliance and industrial control applications.

What package type and pin count does the R5F56604ADFN#30 use, and what are its thermal characteristics?

The R5F56604ADFN#30 uses a 144-pin LFQFP package (PLQP0144KA-B), measuring 20 × 20 mm with 0.5 mm pitch and an exposed thermal pad. It is rated for industrial temperature operation from –40°C to +85°C (D-version), with 5-V tolerant I/O pins and support for deep software standby mode where the RTC continues running-enabling ultra-low-power operation in battery-backed systems.
