For engineers reviewing the R5F56604BGFN#10 datasheet, R5F56604BGFN#10 pinout, R5F56604BGFN#10 application, or R5F56604BGFN#10 equivalent, key selection criteria include its 144-pin LFQFP package with sub-clock oscillator and JTAG support, 120 MHz real-time performance (709 CoreMark), IEC60730 safety features, and dual 12-bit DACs usable as comparator references.

Technical Context

The R5F56604BGFN#10 implements the RXv3 CPU core with single-precision FPU compliant to IEEE 754, collective register bank save, and MPU for memory protection. It integrates an ELC enabling event-triggered peripheral operation without CPU intervention - critical for low-latency motor control and deterministic sensor acquisition.

Clock architecture includes 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 up to 60 MHz, ADCLK up to 60 MHz). The device supports deep software standby with RTC running and four low-power modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604BGFN#10?

The R5F56604BGFN#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 optimized pipeline, on-chip FPU, and zero-wait-state 120 MHz access to both code flash and SRAM - enabling deterministic execution of complex control algorithms in real time.

Does the R5F56604BGFN#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604BGFN#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. Its hardware implementation includes bit-rate switching, flexible data-length payloads, and error confinement - making it suitable for modern industrial networks requiring higher bandwidth than classical CAN.

What package type and pin count does the R5F56604BGFN#10 use?

The R5F56604BGFN#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. This package includes both JTAG and sub-clock oscillator support, distinguishing it from lower-pin-count or oscillator-limited variants in the RX660 family.

How many analog-to-digital and digital-to-analog converter channels does the R5F56604BGFN#10 provide?

The R5F56604BGFN#10 integrates one 12-bit S12ADH analog-to-digital converter with 24 input channels and two 12-bit R12DAb digital-to-analog converter channels. Both DAC outputs can serve as reference voltages for the four-channel analog comparator (CMPC), enabling precision threshold detection without external components.

Is the R5F56604BGFN#10 qualified for IEC60730 Class B compliance, and which hardware safety features does it include?

Yes, the R5F56604BGFN#10 includes dedicated hardware features for IEC60730 Class B compliance: memory protection unit (MPU), Trusted Memory (TM), clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, CRC calculator (CRCA), data operation circuit (DOCA), and register write protection. These are documented in the R01DS0393EJ0100 datasheet and supported by Renesas' functional safety documentation package.
