Product details
Overview
R5F566TAADFM#10 from Renesas is a 120-MHz 32-bit RXv3 microcontroller with double-precision IEEE-754 FPU, 2 MB on-chip code flash, 1 MB SRAM (512 KB + 512 KB expansion), and integrated Ethernet MAC, CAN, SDHI, QSPI, and GLCDC for industrial HMI and networked edge devices.
For engineers reviewing the R5F566TAADFM#10 datasheet, R5F566TAADFM#10 pinout, R5F566TAADFM#10 application, or R5F566TAADFM#10 equivalent, key selection criteria include dual-bank flash for safe firmware updates, 182 GPIOs with 5-V tolerance, RTC with battery backup, IEC60730 safety features, and support for real-time deterministic control via GPTW/MTU3 timers.
Technical Context
The R5F566TAADFM#10 implements the RXv3 CPU core with 698 CoreMark at 120 MHz, double-precision FPU, MPU, and collective register bank save for fast context switching in RTOS environments. It integrates DMACA (8-channel), EXDMAC (2-channel), and DTC (1-channel) for zero-CPU-overhead data movement across peripherals including ETHERC, SDHI, and S12AD.
Clock architecture includes dual PLLs, selectable internal oscillators (HOCO/LOCO), and independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz) enabling precise timing isolation for ADC, Ethernet, and graphics subsystems. The device supports IEC60730 Class B compliance via oscillation-stop detection, CRC acceleration, IWDT windowing, and A/D self-diagnostic functions.
