The 128 KB SRAM supports moderate frame buffers or data logging without external memory. ## WLCSP package — board-level planning That saves board area but demands a controlled reflow profile, a fine-pitch stencil, and typically underfill for mechanical reliability in environments with vibration or thermal cycling. ## Peripheral set for connectivity-heavy designs On-chip peripherals include CANbus, multiple I²C and SPI buses, a Quad-SPI interface, USB OTG, SAI (serial audio interface), and an LCD driver controller. Brown-out detect and a watchdog timer are built in, reducing external supervisor IC count.","metaTitle":"ST STM32L476JGY6UTR ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L476JGY6UTR 32-bit ARM Cortex-M4 MCU, 80 MHz core, 1 MB Flash, 128 KB SRAM, 72-WLCSP package.
