For engineers reviewing the R5F56609FDFP#10 datasheet, R5F56609FDFP#10 pinout, R5F56609FDFP#10 application, or R5F56609FDFP#10 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG + FINE debug support, sub-clock oscillator inclusion, full 24-channel S12ADH ADC, dual-channel R12DAb DAC, and CAN FD channel compliant with ISO 11898-1:2015.

Technical Context

The R5F56609FDFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching. It integrates an ELC for event-driven peripheral coordination without CPU intervention and supports little-endian or big-endian data arrangement.

Its clock system combines an 8–24 MHz main crystal oscillator, 32.768 kHz sub-clock, and selectable on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and frequency dividers for ICLK (up to 120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), PCLKD (60 MHz), FCLK (60 MHz), and BCLK (40 MHz). The MCU includes MPU-based memory protection and Trusted Memory (TM) for secure code execution.

FAQ

What is the maximum operating frequency and core architecture of the R5F56609FDFP#10?

The R5F56609FDFP#10 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core, achieving 709 CoreMark performance. It includes a single-precision IEEE 754 floating-point unit, 113 instructions, and support for little-endian or big-endian data arrangement. Its minimum instruction execution time is one system clock cycle, and it features a 32×32→64-bit multiplier and 32/32→32-bit divider.

Does the R5F56609FDFP#10 include a sub-clock oscillator and real-time clock (RTC)?

Yes, the R5F56609FDFP#10 includes both a sub-clock oscillator interface (SOSC/SOSCI/SOSCO pins) and a fully functional real-time clock (RTCC) module. The RTC supports binary counting and calendar modes, alarm/periodic/carry interrupts, time capture on up to three pins, and adjustment functions for leap year and error correction - all enabled by the included 32.768 kHz crystal connection.

How many analog-to-digital and digital-to-analog converter channels does the R5F56609FDFP#10 support?

The R5F56609FDFP#10 integrates a single 12-bit S12ADH analog-to-digital converter with 24 input channels and a conversion time as low as 0.9 µs at 60 MHz ADCLK. It also includes two 12-bit R12DAb digital-to-analog converter channels, each with output range 0 V to AVCC0, and both DAC outputs can serve as reference voltages for the four-channel CMPC analog comparators.

Is the R5F56609FDFP#10 pin-compatible with other RX660 Group MCUs in the same package?

Yes, the R5F56609FDFP#10 uses the PLQP0144KA-B 144-pin LFQFP package and shares identical pinout with other RX660 Group devices in that package variant - including R5F56608FDFP#10 and R5F566T9FDFP#10. All support JTAG and FINE debug interfaces, 24 ADC inputs, dual DAC outputs, CAN FD TX/RX, and the same power/oscillator/reset pin assignments.

What safety and reliability features does the R5F56609FDFP#10 provide for IEC60730 compliance?

The R5F56609FDFP#10 includes dedicated hardware for IEC60730 Class B compliance: oscillation-stoppage detection for main/sub clocks, A/D converter self-diagnosis and analog input disconnection detection, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with window function, RAM test assistance via DOC, CRCA for data integrity, and register write protection to prevent accidental overwrites - all documented in the R01DS0393EJ0100 datasheet.
