This puts the processing ceiling above most sensor-fusion and motor-control loops — the core can execute a 32-bit multiply-accumulate in a single cycle, which matters for field-oriented control (FOC) of a PMSM at 20 kHz PWM without cycle-stealing from the communication stack. On-chip memory is partitioned as 256 KB flash for program storage, 64 KB SRAM for data, and 32 KB dedicated EEPROM. The EEPROM block is separate from the flash array — it supports byte-wise erase/write without wear-leveling the main program space, useful for storing calibration coefficients or production counters that change infrequently. The pitch is standard for two-layer PCB fan-out — the inner rows of the QFP break out to vias under the body, but the outer rows route directly to the perimeter without a via-in-pad process. ## Peripheral set and connectivity — industrial fieldbus gateway profile The peripheral list includes DMA, LVD, POR, PWM, and WDT. The DMA controller can service the SCI (UART) and SPI peripherals without CPU intervention — a 115200 baud UART stream at 8N1 consumes about 0.9 % of the 160 MHz bandwidth when DMA-fed, leaving the core free for the control algorithm. Connectivity covers CANbus, I²C, LINbus, MMC/SD, SCI, SPI, SSI, and UART/USART. The CAN 2.0B controller supports 29-bit extended identifiers — the message filter bank can be programmed to accept only the relevant CAN IDs, reducing interrupt load on the core. Data converters: 8-channel 12-bit ADC and 2-channel 12-bit DAC. The ADC sample-and-hold time is configurable per channel — for a 10 kHz current-loop update, the conversion completes in under 1 µs at 12-bit resolution, leaving 99 % of the PWM cycle for the control math. ## Supply voltage and temperature grade — industrial enclosure tolerance This covers a 3.3 V regulated rail with 300 mV of dropout headroom, and also accepts an unregulated 5 V rail from a USB VBUS or a 5 V industrial supply — no external LDO is needed if the rail stays within the 5.5 V abs-max. Temperature grade is -40°C to 105°C ambient. The 105°C upper limit is the industrial extended range — a motor-drive enclosure that sees 85°C internal ambient on a hot day still has 20°C of margin before the silicon hits the rated ceiling. Lifecycle status is Active per Renesas. The part is ROHS3 compliant.","metaTitle":"R5F566TAFGFL#10 Renesas RX MCU, 160 MHz, 256 KB Flash","metaDescription":"R5F566TAFGFL#10 Renesas RXv3 32-bit MCU, 160 MHz, 256 KB flash, 64 KB RAM, 32 KB EEPROM, -40 to 105°C, 48-LQFP.
