FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604DGFB#10?

The R5F56604DGFB#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with integrated single-precision FPU, barrel shifter, and 32×32→64-bit multiplier - all running without wait states on 1 MB code flash and 128 KB SRAM.

Does the R5F56604DGFB#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604DGFB#10 includes one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. Its CAN FD implementation includes bit-rate switching, flexible data-length payloads (up to 64 bytes), and hardware message filtering - confirmed in the R01DS0393EJ0100 datasheet section 1.1 and Table 1.1.

What package type and pin count does the R5F56604DGFB#10 use?

The R5F56604DGFB#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with part code PLQP0144KA-B: 20 × 20 mm body, 0.5 mm pitch, and includes both JTAG and sub-clock oscillator functionality. This matches the "144-pin LFQFP with JTAG interface and sub-clock oscillator" configuration detailed in Table 1.2 of the RX660 datasheet.

What safety and reliability features are integrated into the R5F56604DGFB#10 for industrial use?

The R5F56604DGFB#10 integrates MPU (8 protection regions), Trusted Memory (TM) for code flash read protection, register write protection, CRCA (8/32-bit CRC), CAC (clock accuracy monitoring), DOCA (data operation circuit), and comprehensive IEC 60730 self-test functions - including oscillation-stop detection, A/D disconnection check, and RAM test assist - all documented in Section 1.1 and Chapter 27 of R01DS0393EJ0100.

How does the Event Link Controller (ELC) enhance real-time performance in the R5F56604DGFB#10?

The ELC in the R5F56604DGFB#10 allows 83 internal event signals (e.g., timer compare match, A/D end-of-conversion) to directly trigger peripheral actions (e.g., MTU start, D/A update) without CPU or interrupt latency. This enables deterministic, low-jitter operation - such as synchronized PWM and sampling - even during deep software standby, as specified in Section 1.1 and Figure 27.1 of the datasheet.
