FAQ

What is the maximum operating frequency and core architecture of the R5F56604EDFB#10?

The R5F56604EDFB#10 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core, delivering 709 CoreMark performance. It includes a single-precision IEEE 754 floating-point unit, 16 register banks for fast context save/restore, and support for little-endian or big-endian data arrangement - making it suitable for computationally intensive real-time control tasks in the R5F56604EDFB#10-based systems.

Does the R5F56604EDFB#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604EDFB#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. This capability is confirmed in the official Renesas datasheet R01DS0393EJ0100 and enables high-bandwidth communication in industrial networks - a key differentiator for R5F56604EDFB#10 in protocol gateway and distributed control applications.

What package type and pin count does the R5F56604EDFB#10 use?

The R5F56604EDFB#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with type code PLQP0144KA-B, measuring 20 × 20 mm with 0.5 mm pitch. It provides 134 general-purpose I/O pins, including 4 that are 5-V tolerant - matching the physical and electrical interface specifications documented for the R5F56604EDFB#10 in Renesas' RX660 Group datasheet.

Is the real-time clock (RTCC) functional on the R5F56604EDFB#10, and what oscillator does it require?

Yes, the R5F56604EDFB#10 supports the real-time clock (RTCC) function, but only when the sub-clock oscillator (SOSC) is enabled - requiring external 32.768 kHz crystal connections to XT1/XT2 pins. The RTCC provides calendar/time counting, alarm, periodic, and carry interrupts, plus time-capture on up to three pins - all confirmed operational per R5F56604EDFB#10's configuration in the RX660 Group hardware manual.

What safety and reliability features are built into the R5F56604EDFB#10 for industrial use?

The R5F56604EDFB#10 includes multiple hardware-level safety features: memory protection unit (MPU), Trusted Memory (TM) for flash security, CRC calculator (CRCA), clock accuracy measurement circuit (CAC), data operation circuit (DOCA), register write protection, oscillation-stop detection, and A/D self-diagnostic functions - all aligned with IEC60730 Class B requirements. These are integral to the R5F56604EDFB#10's design for certified industrial control applications.
