The exposed pad is the primary heat path; leaving it floating or poorly soldered will push junction temperature above the 85°C industrial ceiling in a sealed enclosure. ## Lifecycle and sourcing posture The base product number STM32L4Q5 covers a range of Flash and RAM density options in the same 48-UFQFN footprint, so a pin-compatible drop-in with different memory sizing is possible within the family without a board spin.","metaTitle":"STM32L4Q5CGU6 ARM Cortex-M4 MCU, 120 MHz, 1 MB Flash","metaDescription":"STM32L4Q5CGU6 32-bit MCU with ARM Cortex-M4 core at 120 MHz, 1 MB Flash, 320 KB SRAM, industrial temp range.
