The 1 MB Flash gives room for a full application stack plus an OTA update staging area — useful when the product ships with field-upgradeable firmware. 128 KB SRAM is enough for moderate data buffering and RTOS task stacks without external memory. ## Connectivity and peripheral set for system integration The 65 GPIOs in the WLCSP package are sufficient for a sensor hub or a control panel with a small display. On-chip 12-bit ADCs (16 channels) and dual 12-bit DACs cover analog front-end needs without an external converter. ## Package and assembly considerations for the WLCSP variant The package is surface-mount only; no socket option exists.","metaTitle":"STM32L476MGY6TR STM32L4 MCU, ARM Cortex-M4, 80 MHz","metaDescription":"STM32L476MGY6TR 32-bit ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash, 128 KB RAM, 81-WLCSP, -40°C to 85°C.
