Core compute and memory budget
The R5F566TEBGFL#10 runs the RXv3 core at 160 MHz — the instruction pipeline and flash prefetch buffer are tuned so that most single-cycle instructions execute at that clock without wait states for cached code. The 512 KB on-chip flash and 64 KB SRAM leave room for a real-time OS kernel, a moderate application stack, and a communication buffer for CAN or Ethernet frames. A separate 32 KB EEPROM block handles parameter storage and calibration data without wearing the main flash — useful for field-updatable firmware where the EEPROM endurance (typically 1M cycles) outlasts the flash sector erase cycles.
Peripheral set and analog integration
The part integrates eight 12-bit ADC channels and two 12-bit DAC channels — enough for a three-phase motor current-sense plus a reference voltage output, all on a single 48-pin LQFP. The DMA controller can shuttle ADC results directly to RAM without CPU intervention, keeping the core free for control loops. Connectivity covers CANbus, I²C, SPI, SCI (UART), LINbus, and an EBI/EMI bus for external memory or FPGA glue logic. The MMC/SD interface supports data logging to an SD card without an external controller. Built-in LVD (low-voltage detect) and POR (power-on reset) eliminate the need for an external supervisor IC in most designs — the MCU holds the reset line until the supply rail is stable above the threshold.
Sourcing and lifecycle posture
The part is ROHS3 compliant.
