For engineers reviewing the R5F56604CDFB#10 datasheet, R5F56604CDFB#10 pinout, R5F56604CDFB#10 application, or R5F56604CDFB#10 equivalent, this page delivers verified specifications, package mapping to PLQP0144KA-B (144-pin LFQFP), functional pin roles, IEC60730-compliant safety features, and validated alternative MCUs for migration or second-sourcing.

Technical Context

The R5F56604CDFB#10 implements the RXv3 CPU core with single-precision FPU compliant with IEEE 754, supporting 709 CoreMark at 120 MHz and collective register bank save for fast context switching. It integrates an ELC (Event Link Controller) enabling interrupt-free inter-module triggering - critical for deterministic real-time response in motor control loops.

Its clock system combines a 8–24 MHz external main oscillator, 32.768 kHz sub-clock for RTC, and on-chip HOCO/LOCO oscillators, with independent PLL and dedicated IWDT clock. Power management includes four low-power modes, deep software standby with RTC active, and voltage monitoring across three LVD levels - all certified for IEC60730 Class B compliance.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604CDFB#10?

The R5F56604CDFB#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark under those conditions. This performance stems from the RXv3 CPU core's optimized pipeline, zero-wait-state 128 KB SRAM, and 1 MB code flash with no access wait states at full speed - enabling deterministic execution of real-time control algorithms without cache misses or flash stalls.

Does the R5F56604CDFB#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604CDFB#10 includes one CAN FD module compliant with ISO 11898-1:2015 for both standard and extended frames. It supports bit rates up to 5 Mbps in the data phase and includes built-in message filtering, FIFO buffering, and error counters - eliminating the need for external CAN FD controllers in industrial gateway and drive applications.

What package type and pin count does the R5F56604CDFB#10 use?

The R5F56604CDFB#10 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package measuring 20 × 20 mm with 0.5 mm pitch and an exposed thermal pad. This package supports 134 general-purpose I/O pins, including 4 with 5-V tolerance, and integrates dedicated terminals for main/sub-clock oscillators, CAN FD differential pairs, and MTU3a PWM outputs.

How does the R5F56604CDFB#10 meet IEC60730 Class B safety requirements?

The R5F56604CDFB#10 integrates multiple hardware safety mechanisms required for IEC60730 Class B: oscillation-stop detection, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOCA), memory protection unit (MPU), register write protection, and Trusted Memory (TM). These features are documented in the R01DS0393EJ0100 datasheet and enable certified self-test and fault containment without external components.

What are the key analog peripherals integrated into the R5F56604CDFB#10?

The R5F56604CDFB#10 integrates a 24-channel 12-bit S12ADH A/D converter with scan modes, group prioritization, and self-diagnostic disconnection detection; a 2-channel 12-bit R12DAb D/A converter usable as comparator reference; four analog comparators (CMPC); and an on-chip temperature sensor with ±1.0°C relative precision - all synchronized via the Event Link Controller for coordinated signal acquisition and conditioning.
