It packs 256 KB of Flash program memory, 64 KB of RAM, and 32 KB of on-chip EEPROM — the latter saving a board-level serial EEPROM in many designs. The peripheral set includes CAN, I²C, SPI, UART, LIN, SSI, and an external bus interface (EBI/EMI), making it a fit for industrial I/O modules, motor drives, and CAN-based sensor hubs. Operating temperature spans -40°C to 85°C, covering factory-floor and outdoor telecom enclosures without the extended-range premium. ## 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). For analog I/O, it integrates an 8-channel 12-bit ADC and a 2-channel 12-bit DAC — enough for current-sense feedback and analog setpoint generation in a motor-drive or power-converter application. The 33 I/O lines in the 48-LQFP package leave room for a parallel LCD or external SRAM via the EBI while still supporting serial peripherals. ## Active lifecycle — no LTB risk for new designs Renesas lists this part as Active (current production). There is no last-time-buy notice or NRND flag. 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.","metaTitle":"R5F566TABDFL#10 Renesas RX 32-bit MCU, 160 MHz, 256 KB Flash","metaDescription":"R5F566TABDFL#10 Renesas RXv3 32-bit MCU with 160 MHz core, 256 KB Flash, 64 KB RAM, 32 KB EEPROM.
