Product details
Overview
R5F56604HDFB#10 from Renesas is a 32-bit RXv3 microcontroller with 120 MHz maximum operating frequency, 1 Mbyte on-chip code flash, 128 Kbytes SRAM, and integrated CAN FD, 12-bit A/D and D/A converters, RTC, and remote control signal receiver - deployed in industrial HMI, motor control gateways, and smart sensor nodes requiring deterministic real-time response and IEC 60730 compliance.
For engineers reviewing the R5F56604HDFB#10 datasheet, R5F56604HDFB#10 pinout, R5F56604HDFB#10 application, or R5F56604HDFB#10 equivalent, this page delivers verified specifications, package mapping to PLQP0144KA-B (144-pin LFQFP), validated pin functions, real-world use cases, and two confirmed alternative MCUs with documented functional and packaging differences.
Technical Context
The R5F56604HDFB#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching. It integrates an ELC (Event Link Controller) enabling interrupt-free inter-module triggering - critical for low-latency motor control and sensor fusion.
Its clock system combines an 8–24 MHz external main oscillator, 32.768 kHz sub-clock for RTC, and selectable on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PCLKA (up to 120 MHz), PCLKB (up to 60 MHz), and ADCLK (up to 60 MHz) domains - allowing mixed-speed peripheral operation without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F56605HDFB#10 | Same RX660 Group, identical 144-pin LFQFP package and 1 Mbyte flash, but includes JTAG interface (R5F56604HDFB#10 has FINE-only debugging). | Required when boundary-scan testing or complex trace-based debugging is needed during production test or development. | Select R5F56605HDFB#10 if JTAG is mandatory; otherwise R5F56604HDFB#10 offers lower debug pin count and reduced layout complexity. |
| R5F56602HDFB#10 | Same package and core, but 512 Kbyte code flash and no CAN FD module - retains all other peripherals including ELC, MTU3a, and RTC. | Suitable for cost-sensitive applications where CAN FD is unused and firmware size fits within 512 Kbyte, such as standalone sensor controllers. | Choose R5F56602HDFB#10 only when CAN FD is unnecessary and flash headroom is sufficient - avoids over-specifying silicon. |
Compared with R5F56605HDFB#10, the R5F56604HDFB#10 trades JTAG for reduced debug pin count and simplified routing; compared with R5F56602HDFB#10, it adds CAN FD and 512 Kbyte flash headroom - making it optimal for fieldbus-connected industrial edge devices requiring future-proof protocol support.
