Overview
R5F5671EHDFB#10 from Renesas is a 32-bit RXv3 microcontroller operating at up to 120 MHz, featuring double-precision IEEE-754 FPU, 2 MB on-chip code flash with dual-bank support, 384 KB SRAM, and integrated CAN, USB 2.0 FS, SD host interface, QSPIX, and capacitive touch sensing - deployed in industrial HMI and smart metering systems requiring real-time control and secure firmware updates.
For engineers reviewing the R5F5671EHDFB#10 datasheet, R5F5671EHDFB#10 pinout, R5F5671EHDFB#10 application, or R5F5671EHDFB#10 equivalent, key selection criteria include its 144-pin LFQFP package (PLQP0144KA-B), 120 MHz CPU performance (707 CoreMark), TSIP-based AES256/SHA256 encryption, RTC with battery backup, and IEC60730-compliant self-diagnostic features for functional safety-critical designs.
Technical Context
The R5F5671EHDFB#10 implements the RXv3 CPU core with 16 general-purpose 32-bit registers, double-precision FPU (16×64-bit data registers), and collective register bank save across 16 banks. It supports little-endian or big-endian data arrangement and executes instructions in single-cycle latency at 120 MHz.
Its clock system integrates PLL, sub-clock oscillator (32.768 kHz), LOCO/HOCO (240 kHz / 16–20 MHz), and IWDT-dedicated 120 kHz oscillator. Peripheral clocks are independently configurable: ICLK up to 120 MHz (CPU, QSPIX), PCLKA up to 120 MHz (MTU3a, RSPI), PCLKB up to 60 MHz (most peripherals), and ADCLK up to 60 MHz (S12AD units).

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 |
|---|---|---|---|
| R5F5670EDFLB#10 | Same RX671 Group, 100-pin LFQFP (PLQP0100KB-B), 1 MB flash, 256 KB SRAM, no SDHI or QSPIX - smaller footprint, reduced peripheral count. | Limited to space-constrained nodes without local storage or serial flash boot; suitable for sensor concentrators without HMI. | Select when board area is critical and SD/QSPIX functionality is unnecessary; verify pin compatibility for GPIO-only reuse. |
| R5F566TEHDFB#10 | RX66T Group, same 144-pin LFQFP, 160 MHz CPU, 2 MB flash, but optimized for motor control (3× MTU3, 3× 16-bit ADC, no CTSU or SDHI). | Targeted at inverter drives and servo controllers; lacks capacitive touch, RTC battery backup, and secure boot features of R5F5671EHDFB#10. | Choose for high-performance motor control where TSIP, CTSU, and SDHI are not required; not drop-in due to peripheral register map differences. |
Compared with R5F5670EDFLB#10, the R5F5671EHDFB#10 adds SDHI, QSPIX, and CTSU for HMI/storage use cases; versus R5F566TEHDFB#10, it trades motor-specific timers and ADC channels for security, RTC, and human interface features - making it optimal for certified, connected, user-facing industrial devices.
