160 MHz RXv3 MCU with on-chip EEPROM — fit for industrial control and CAN-based nodes
The Renesas R5F566TABDFL#10 is a 32-bit microcontroller from the RX family, built around the RXv3 core running at 160 MHz.
256 KB Flash, 64 KB RAM, 32 KB EEPROM — memory budget for code and data
The 256 KB Flash (256K x 8) and 64 KB RAM handle control firmware and data buffering. The 32 KB EEPROM stores calibration constants and fault logs without an external I²C EEPROM.
Connectivity and analog — CAN, SPI, I²C, 8-channel 12-bit ADC, 2-channel 12-bit DAC
The R5F566TABDFL#10 carries CAN, I²C, SPI, UART, LIN, SSI, and an external memory interface (EBI/EMI).
Renesas lists this part as Active (current production). For production BOMs that need dual sourcing, the pin-compatible R5F566TAFGFL#10 extends the temperature range to 105°C — useful if the final assembly ends up in a hotter environment than the 85°C rating of this variant. The R5F566TEBGFL#10 is another 160 MHz RXv3 sibling with the same 48-LQFP footprint but different memory partitioning; verify the Flash/RAM split against your firmware size before substituting.
