For engineers reviewing the R5F56604BGFM#10 datasheet, R5F56604BGFM#10 pinout, R5F56604BGFM#10 application, or R5F56604BGFM#10 equivalent, key selection criteria include its 144-pin LFQFP package, dual D/A output capability, sub-clock oscillator support for RTC, JTAG/FINE debug interfaces, and IEC60730-compliant safety features including MPU, CAC, and register write protection.

Technical Context

The R5F56604BGFM#10 implements the RXv3 CPU core with single-precision FPU compliant to IEEE 754, delivering 709 CoreMark at 120 MHz. Its clock system integrates main (8–24 MHz crystal), sub-clock (32.768 kHz), and high-speed on-chip oscillators (16/18/20 MHz HOCO), with PLL-based system clock scaling up to 120 MHz and independent peripheral clocks (PCLKA up to 120 MHz, PCLKB up to 60 MHz, ADCLK up to 60 MHz).

It features event-driven architecture via the Event Link Controller (ELC), enabling 83 internal event signals to trigger peripheral operations-including MTU3a PWM generation, A/D conversion starts, and RTC time capture-without CPU intervention, even in deep software standby mode where RTC continues running.

FAQ

What is the maximum operating frequency and flash access performance of the R5F56604BGFM#10?

The R5F56604BGFM#10 operates at up to 120 MHz with zero-wait-state access to both its 1 Mbyte on-chip code flash memory and 128 Kbytes of SRAM. This enables deterministic real-time execution of complex control algorithms and eliminates pipeline stalls during instruction fetch or data read/write operations, critical for motor control and industrial automation applications where timing predictability is essential. The R5F56604BGFM#10 achieves 709 CoreMark at this frequency.

Does the R5F56604BGFM#10 support real-time clock (RTC) functionality, and what are the requirements?

Yes, the R5F56604BGFM#10 supports RTC functionality with calendar and binary counting modes, alarm and periodic interrupts, and time capture on up to three pins. To enable RTC, a 32.768 kHz crystal must be connected to RTCXTAL/RTCEXTAL pins, and the sub-clock oscillator must be enabled. The device's 144-pin LFQFP package includes SOSC support, confirming RTC capability. Without the sub-clock oscillator, RTC cannot operate and must be disabled per the hardware manual.

What safety and functional safety features does the R5F56604BGFM#10 provide for IEC60730 compliance?

The R5F56604BGFM#10 integrates multiple hardware-based safety features required for IEC60730 Class B compliance, including a memory protection unit (MPU), clock frequency accuracy measurement circuit (CAC), oscillation-stop detection, register write protection, CRC calculator (CRCA), and data operation circuit (DOCA) for RAM testing. These features are implemented in silicon and do not rely on software-only checks, enabling robust self-diagnostic capability for appliances and industrial controls. The R5F56604BGFM#10 also supports Trusted Memory (TM) to protect firmware IP.

Can the R5F56604BGFM#10 generate complementary PWM waveforms with dead-time control for 3-phase inverter drives?

Yes, the R5F56604BGFM#10's MTU3a module supports complementary PWM output mode with automatic dead-time insertion, non-overlapping waveform generation, and synchronous reset. It provides up to 9 channels (8×16-bit + 1×32-bit), 28 pulse I/Os, and integrated Port Output Enable 3 (POE3a) for hardware-triggered shutdown on overcurrent. The R5F56604BGFM#10 uses these features to drive gate drivers in BLDC/PMSM inverters while maintaining safe shoot-through prevention without CPU intervention.

What debugging interfaces are supported by the R5F56604BGFM#10, and are they available in the 144-pin package?

The R5F56604BGFM#10 supports both JTAG (IEEE 1149.1) and FINE (single-wire) debugging interfaces. In the 144-pin LFQFP package (PLQP0144KA-B), JTAG is fully implemented with dedicated TMS, TDI, TDO, TCK, and TRST# pins, enabling full boundary-scan, real-time trace, and flash programming. FINE is also available on a separate pin, offering a low-pin-count alternative for production programming and debug. Both interfaces are confirmed active in this package variant per the RX660 Group datasheet.
