This MCU packs a broad peripheral selection: CANbus for industrial fieldbus, USB OTG for host/device connectivity, QSPI for fast external memory expansion, and SAI for audio serial interfaces. The exposed pad (if present on the variant) needs a thermal via stitch under the package for adequate heat dissipation when running the core at 80 MHz with multiple peripherals active. For dual-sourcing resilience, the STM32L151CBU6A (Cortex-M3, 32 MHz, 37 I/O) is a functional alternative but with a smaller peripheral set and lower core speed — not a pin-compatible drop-in.","metaTitle":"STM32L475RCT6 MCU, ARM Cortex-M4 80MHz, 256KB Flash, 64-LQFP","metaDescription":"STM32L475RCT6 32-bit MCU with ARM Cortex-M4 core at 80MHz, 256KB Flash, 128KB SRAM, rich connectivity including CAN and USB OTG.
