It targets industrial control, motor drive, and safety-compliant embedded systems requiring deterministic real-time performance and IEC60730 support.

For engineers reviewing the R5F56604BGFP#10 datasheet, R5F56604BGFP#10 pinout, R5F56604BGFP#10 application, or R5F56604BGFP#10 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, G-grade temperature range (–40°C to +105°C), sub-clock oscillator inclusion, JTAG/FINE debug interfaces, and full peripheral set including MTU3a timer, ELC, and dual-channel 12-bit D/A output usable as comparator reference.

Technical Context

The R5F56604BGFP#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. Its clock system integrates main (8–24 MHz crystal), sub (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and configurable peripheral clock domains (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).

Peripheral architecture centers on event-driven operation via the Event Link Controller (ELC), enabling inter-module triggering without CPU intervention. Safety features include MPU (8 regions), Trusted Memory (TM) protection for code flash, register write protection, CAC for clock accuracy monitoring, CRCA for CRC generation, and DOCA for 32-bit data operations - all supporting IEC60730 Class B compliance.

FAQ

What is the maximum operating frequency and core type of the R5F56604BGFP#10?

The R5F56604BGFP#10 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core. This core delivers 709 CoreMark performance and includes hardware support for single-precision floating-point arithmetic per IEEE 754, barrel shifting, and 32×32→64-bit multiplication. The R5F56604BGFP#10 achieves zero-wait-state execution from both code flash and SRAM at this speed, enabling deterministic real-time response in demanding control applications.

Does the R5F56604BGFP#10 support CAN FD, and what protocol compliance does it meet?

Yes, the R5F56604BGFP#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) identifier frames at data rates up to 5 Mbps. It includes dedicated message RAM, flexible filtering, and error handling consistent with automotive and industrial CAN FD requirements. The R5F56604BGFP#10's CAN FD implementation operates independently of CPU load via the ELC, allowing seamless integration into time-critical distributed control networks.

What analog peripherals are included in the R5F56604BGFP#10, and how are they configured?

The R5F56604BGFP#10 includes a 24-channel 12-bit S12ADH analog-to-digital converter with 0.9 µs minimum conversion time (at 60 MHz ADCLK), a dual-channel 12-bit R12DAb digital-to-analog converter, and a 4-channel CMPC analog comparator. The ADC supports group scanning with priority control, digital comparison, and self-diagnostic functions. Both DAC outputs can serve as reference voltages for the comparators. All analog blocks are clocked from dedicated peripheral domains (PCLKD) and support event-triggered operation via the ELC - a capability fully implemented in the R5F56604BGFP#10.

How does the R5F56604BGFP#10 support functional safety standards like IEC60730?

The R5F56604BGFP#10 provides hardware-level features essential for IEC60730 Class B compliance: memory protection unit (MPU), register write protection, clock accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOCA), oscillation-stop detection, and independent watchdog timer (IWDT) with windowing. It also includes ADC self-test, analog input disconnection detection, and RTC initialization safeguards. These capabilities are documented in the R5F56604BGFP#10 datasheet and supported by Renesas' safety manual, enabling certified safety firmware development without external components.

What package and temperature grade does the R5F56604BGFP#10 use, and is the sub-clock oscillator included?

The R5F56604BGFP#10 uses the 144-pin LFQFP PLQP0144KA-B package (20 × 20 mm, 0.5 mm pitch) and is rated for the G-grade industrial temperature range of –40°C to +105°C. It includes both JTAG and FINE debug interfaces, and - critically - integrates the sub-clock oscillator (SOSC) pins (XT1/XT2), enabling full RTC functionality. This configuration is confirmed in Table 1.2 of the R01DS0393EJ0100 datasheet and distinguishes the R5F56604BGFP#10 from variants lacking SOSC or JTAG.
