For engineers reviewing the R5F56604AGFN#30 datasheet, R5F56604AGFN#30 pinout, R5F56604AGFN#30 application, or R5F56604AGFN#30 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, G-grade temperature range (–40°C to +105°C), sub-clock oscillator support for RTC operation, JTAG/FINE debug interfaces, and full peripheral complement including MTU3a (9-channel), 8-channel DMACA, and ELC event linking.

Technical Context

The R5F56604AGFN#30 implements the RXv3 CPU core with single-precision FPU compliant with IEEE 754, supporting 709 CoreMark at 120 MHz and collective register bank save for fast interrupt response. Its clock system integrates main (8–24 MHz crystal), sub (32.768 kHz), and on-chip oscillators (HOCO/LOCO), with independent PLL 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 module actions-including MTU3a PWM generation, S12ADH conversion starts, and IWDT refresh-without CPU intervention. The MCU includes hardware safety features: MPU (8 regions), Trusted Memory (TM) for code protection, CRC calculator (CRCA), CAC clock accuracy monitoring, and DOCA for 32-bit data operations.

FAQ

What is the maximum operating frequency and core architecture of the R5F56604AGFN#30?

The R5F56604AGFN#30 operates at up to 120 MHz using the 32-bit RXv3 CPU core with single-precision floating-point unit (FPU) compliant with IEEE 754. It achieves 709 CoreMark at full speed and supports collective register bank save for low-latency interrupt handling. Its memory subsystem delivers no-wait access to both 1-Mbyte code flash and 128-Kbyte SRAM at 120 MHz.

Does the R5F56604AGFN#30 support real-time clock (RTC) functionality, and what are the requirements?

Yes, the R5F56604AGFN#30 supports RTC via the RTCC module, but requires the sub-clock oscillator (SOSC) to be enabled using an external 32.768 kHz crystal connected to SOSCIN/SOSCOUT pins. The device includes calendar/time counting modes, alarm and periodic interrupts, and time-capture on up to three pins. Without SOSC, RTCC must be disabled per the hardware manual initialization procedure.

What communication interfaces does the R5F56604AGFN#30 include, and which support CAN FD?

The R5F56604AGFN#30 integrates one CAN FD channel compliant with ISO 11898-1:2015 (supporting both standard and extended frames), 13 SCI channels (with flexible modes including UART, SPI, I²C, and LIN), two RIIC interfaces (400 kbps Fast Mode), one RSPId (30 Mbps), and one REMCa for IR signal reception. CAN FD is implemented in the dedicated CANFD module and uses CTX0/CRX0 pins.

How many analog-to-digital and digital-to-analog converter channels does the R5F56604AGFN#30 provide?

The R5F56604AGFN#30 includes a single 12-bit S12ADH analog-to-digital converter with 24 input channels and a minimum conversion time of 0.9 µs at 60 MHz ADCLK. It also provides two 12-bit R12DAb digital-to-analog converter channels, each capable of outputting 0 V to AVCC0 and usable as reference voltages for the four-channel CMPC analog comparators.

What safety and reliability features are built into the R5F56604AGFN#30 for IEC 60730 compliance?

The R5F56604AGFN#30 includes multiple hardware features for IEC 60730 Class B compliance: memory protection unit (MPU), Trusted Memory (TM) for code protection, register write protection, CRC calculator (CRCA), clock frequency accuracy measurement circuit (CAC), data operation circuit (DOCA), oscillation-stop detection, and A/D self-diagnosis. These enable robust self-test routines without external components.
