For engineers reviewing the R5F56604BDFN#10 datasheet, R5F56604BDFN#10 pinout, R5F56604BDFN#10 application, or R5F56604BDFN#10 equivalent, key selection criteria include CAN FD compliance (ISO 11898-1:2015), 144-pin LFQFP package with sub-clock oscillator and JTAG interface, 2.7–5.5 V supply range, IEC60730 safety support, and real-time clock operation in deep software standby mode.

Technical Context

The R5F56604BDFN#10 implements the RXv3 CPU core with single-precision FPU compliant to IEEE 754, supporting 709 CoreMark at 120 MHz and collective register bank save for fast context switching. 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 fine-grained peripheral clock domain control (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB/PCLKD up to 60 MHz).

It features hardware-assisted safety functions including MPU (8 regions, 16-byte granularity), Trusted Memory (TM) for code flash protection, CRC calculator (CRCA) with configurable polynomials, clock accuracy measurement (CAC), and register write protection - all aligned with IEC60730 Class B requirements. The ELC enables interrupt-free inter-module event linking, while DMACAa (8-channel) and DTCb (1-channel) support deterministic data movement without CPU intervention.

Does the R5F56604BDFN#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604BDFN#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. It includes dedicated message RAM, flexible filtering, and error handling logic - enabling robust communication in industrial networks and automotive subsystems using the R5F56604BDFN#10.

What package type and pin count does the R5F56604BDFN#10 use?

The R5F56604BDFN#10 is housed in a 144-pin Low-profile Quad Flat Package (LFQFP) with part code PLQP0144KA-B - measuring 20 × 20 mm with 0.5 mm pitch and an exposed thermal pad. This package includes JTAG and FINE debug interfaces, sub-clock oscillator pins (XT1/XT2), and supports 5-V tolerant I/O, confirming its mechanical and electrical identity as the R5F56604BDFN#10.

What safety certifications and hardware features does the R5F56604BDFN#10 provide for IEC60730 compliance?

The R5F56604BDFN#10 includes dedicated hardware for IEC60730 Class B compliance: memory protection unit (MPU), Trusted Memory (TM) for flash protection, clock accuracy measurement circuit (CAC), oscillation-stop detection, independent watchdog timer (IWDT) with window function, CRC calculator (CRCA), and register write protection. These features are documented in the R5F56604BDFN#10 datasheet and enable certified self-test and fault detection without software overhead.
