Product details
Overview
R5F5671EHDFP#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, smart metering, and secure IoT edge nodes.
For engineers reviewing the R5F5671EHDFP#10 datasheet, R5F5671EHDFP#10 pinout, R5F5671EHDFP#10 application, or R5F5671EHDFP#10 equivalent, key selection criteria include its 145-pin TFLGA (0.65-mm pitch) package, IEC60730-compliant safety features (TSIP, MPU, self-diagnostic A/D), RTC with battery backup, and 12-bit dual-unit ADC supporting analog input disconnection detection.
Technical Context
The R5F5671EHDFP#10 implements the RXv3 CPU core with 113 instructions, including DSP and floating-point extensions, and supports little-endian or big-endian data arrangement. Its clock system integrates PLL, sub-clock oscillator (32.768 kHz), and dedicated IWDT oscillator (120 kHz), enabling independent domain clocking: ICLK up to 120 MHz for CPU/QSPIX, PCLKA up to 120 MHz for MTU/RSPI, and PCLKB up to 60 MHz for most peripherals including A/D converters.
It features three DMA controllers - DMACAb (8 channels), EXDMACa (2 channels), and DTCb (1 channel) - coordinated via Event Link Controller (ELC) for hardware-triggered transfers without CPU intervention. The CTSUa supports both self- and mutual-capacitance modes (up to 64 keys), while TSIP provides AES128/192/256, RSA, ECC, TRNG, and key protection for secure firmware updates and data encryption.
