For engineers reviewing the R5F56609ADFN#10 datasheet, R5F56609ADFN#10 pinout, R5F56609ADFN#10 application, or R5F56609ADFN#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 A/D converter, dual-channel R12DAb D/A output, and CAN FD compliance per ISO 11898-1:2015.

Technical Context

The R5F56609ADFN#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-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 external main oscillator, 32.768 kHz sub-clock, and selectable on-chip oscillators (LOCO/HOCO/IWDT), with independent PLL synthesis enabling up to 120 MHz ICLK and configurable PCLKA/PCLKB/PCLKD domains for peripheral timing isolation.

FAQ

What is the package type and pin count of the R5F56609ADFN#10?

The R5F56609ADFN#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with PLQP0144KA-B mechanical outline - 20 × 20 mm body, 0.5 mm pitch, and exposed thermal pad. This package supports full peripheral complement including all 24 A/D channels, dual D/A outputs, CAN FD, and JTAG/FINE debugging interfaces as specified in the R01DS0393EJ0100 datasheet.

Does the R5F56609ADFN#10 include a sub-clock oscillator and real-time clock (RTCC)?

Yes, the R5F56609ADFN#10 includes both a sub-clock oscillator (SOSC) and real-time clock controller (RTCC). The RTCXTAL/RTCEXTAL pins support connection of a 32.768 kHz crystal, enabling calendar/timekeeping functions, alarm interrupts, time capture, and deep software standby mode with RTC continuity - confirmed in Table 1.2 and Section 27 of the R01DS0393EJ0100 datasheet.

What is the maximum A/D conversion rate and resolution supported by the R5F56609ADFN#10?

The R5F56609ADFN#10 integrates the S12ADH 12-bit A/D converter with 24 input channels and a minimum conversion time of 0.9 µs per channel when ADCLK runs at 60 MHz. It supports scan modes (single, continuous, 3-group), digital comparison, self-diagnosis, and analog input disconnection detection - all verified in Section 23 of the R01DS0393EJ0100 datasheet.

Is CAN FD functionality available on the R5F56609ADFN#10, and which standard does it comply with?

Yes, the R5F56609ADFN#10 includes a CAN FD module (CANFD) compliant with ISO 11898-1:2015 for both standard and extended frames. It supports bit rates up to 5 Mbps in FD mode and provides dedicated message RAM, error counters, and loopback/self-test modes - explicitly stated in Table 1.1 and Section 34 of the R01DS0393EJ0100 datasheet.

What debugging interfaces are supported by the R5F56609ADFN#10?

The R5F56609ADFN#10 supports both JTAG (IEEE 1149.1) and FINE (single-wire) debugging interfaces. JTAG provides full boundary-scan, real-time trace, and on-chip programming; FINE enables minimal-pin debugging and programming in space-constrained layouts - detailed in Section 2.3 and Table 1.1 of the R01DS0393EJ0100 datasheet.
